J B Weld TwunTube

熱に強いエポキシパテはコレしか無い、他にも強度ならネジ切りできる物もあるけど、火器類に使うと溶ける、アルストの火口のオリフィス作りや、シングルバーナーのアルミと真鍮燃料ホースの違金属の接着に使った。300度かな、400度になると燃えて白くスカスカになりポロっと取れます。失敗したのを取り除く時はバーナーで燃やすのが早い。 以下、蛇足でレビュー 外付けの給湯器が凍結で配管が割れ水(お湯)が漏れたので、大家さんに修理を依頼したら、修理代の半分の金額を持ってくれと言われ10万も取られた、半分で10万？なら20万？新しいのと交換出来るのでは？と思ったが。業者が一人で来て修理、大家さんは近くに居なく自分もバイトで居ない平日昼間に立ち会いもなく、夕方帰宅した時は使える様になっていた。交換では無く修理。 どんな修理か本体のネジ止めを外して中を確認すると、1cmほど割れた熱交換機の銅パイプを何かで埋めただけ。その前の古い修理歴もあった。コレだけで高額な修理代？ その後すぐ引越しで就職の忙しい時期、クレームも付ける暇なく、年数たち偶然このJBウェルドを知り、あー、あの時は何か特殊な資材かと思っていたが正体はコレかと判り、JBウェルドを使う度にあの時の事を思い出し、コレで10万浮いたと自分を納得させってw、そんな事は無いですが、使う度にトラウマになってます。良い仕事をしてくれますね。

チューブから絞り出す時はかなり力が必要です。 むらにならない様に灰色になるまでしっかり混ぜないと固まりません。 臭いはちょっときつめですが、かなり固く固まります！

2回目の、購入です結構よかったです。

今までいろんなエポキシ接着剤を試したけど最強かも？硬化後に完全に固くなりヤスリがけできるのが良いと思います。

接着力はいいんだけど、チュウブが漏れているのかネバネバするし、なかなか中身が出てこないで苦労する。冬で気温が低いせいか判らないが。前回は日本語バージョンを購入したんだけど、ネバネバは同じだった。日本製でよいのがあるのではないかと思う。次はもういいです。

金属板の劣化個所及び瀬戸物の小さな欠け個所に使ってみましたが、双方しっかり固着して、やすり掛けもでき、表面をつるつるにできました。やっすりで削った感じでは固さは十分と思われ、２液の混ぜ合わせ、塗布も簡単に行えました。色がグレーですので、さすがに瀬戸物につけると目立ちますが、小さな欠けで気にならないレベルで有れば使用可能と思われます。捨てるにはもったいないものの補修には最適と思います。

２種類の混合型でかなり強固に接合できます。 それこそ硬化後の不要箇所の削除等の整形に苦労するほどです。 接合時にある程度整形しておくことをおすすめします。 耐熱性が高いというのも他の同種にはあまり見られない良い特徴の一つだと思います。 今回使用したかったパターンは２つで、１つはやや力がかかる比較的面の広いパーツの補修で熱がかかる箇所に近いのですが、硬化後はびくともしません。 熱でやや変色があるくらいです。 ２つ目は少し細いのですが衝撃が伝わるパーツで同じ細さに整形していました。 硬化後の頑丈さは申し分なかくそれなりの回数には耐えてくれましたが、やはり衝撃が伝わるからか接合箇所から折れてしまいました。 これらのことから私が使用したい環境では、盛り付けが可能で静圧や熱に強い反面、細い＆衝撃が伝わるようなパーツには適さない、とわかりました。 とは言え、強力なことに変わりなく、特にパーツの形状で溶接困難な箇所の接合や補修に効果を発揮すると思います。

2回ほど買いました。熱にもある程度強いですね。

I bought this JB Weld Original Cold-Weld epoxy specifically to repair two leaking bathroom taps that were dripping constantly from the base and joints. The taps are old chrome ones and I didn’t want to replace the whole thing yet, so I decided to give JB Weld a try. Application was straightforward. I cleaned the area thoroughly, dried it completely (used a hairdryer), mixed the two parts of the epoxy, and applied it generously around the leaking joints and base. It has a good working time before it starts to thicken, which gave me time to position it properly. I let it cure for the full 24 hours as recommended before turning the water back on. The result? Completely stopped the leaks. No more dripping, even under normal hot/cold water use and daily pressure. It bonds incredibly well to the metal and has stayed rock solid. I was worried about it holding up in a constantly wet bathroom environment, but weeks later it still looks and performs like new. Pros: Extremely strong once cured (steel-reinforced really makes a difference) Waterproof and heat-resistant enough for bathroom use Easy to mix and apply Great value – one pack does multiple small repairs Cons: None in my case. It does have a bit of a smell while mixing, but that disappears quickly. If you have leaking taps, pipe joints, or any metal repair in a wet area, this stuff is brilliant. Highly recommend – it’s saved me from calling a plumber twice now!

Una delle colle bicomponenti più resistenti che abbia mai usato. Attenzione che però rimane abbastanza liquida, quindi per incollaggi veritcali serve vincolare il pezzo

to repair a fountain cement fiber statue my son accidentally fell into and knocked over and broke. One arm had broken into four pieces. Thankfully, it wasn't the arm that held the water outlet, so it was repairable. I've used JB Weld putties for years and when I found this, I knew it was exactly what I needed so I bought two boxes of it. I only needed one box for this repair though. I applied the epoxy to each piece, one at a time and let each piece cure for a week at a time before adding each subsequent piece. It took forever, but I had to do it on the weekends in-between working. Each piece was held in place by straps until they were set. After all the pieces were epoxied and cured, I sanded it, re-stained it and finished with a sealant. That was 3 years ago and she still looks as good as the day I put her back in service! I've posted pictures of the broken pieces, epoxied pieces and the finished statue and fountain. The last picture was taken today. I cleaned the fountain today, so that's why it's not running, but as you can see, the statue is still in one piece and you can't even see where the repair was done on it. The white spots are where the stain has worn off in the last 3 years. If you need to repair anything heavy, buy this. Best stuff on the planet for repairs and worth every penny spent on it.

El material se ha de mezclar bien, un tubo tiene la resina y el otro el endurecedor. Para que pegue bien las superficies han de estar bien limpias y dejar reposar mínimo 24h si se le quiere dar un uso intensivo a la pieza. Una vez secado tiene un aspecto de plástico gris. El equivalente en KG/cm2 es de 278,4156. Tenedlo en cuenta por si necesitáis una unión más potente.

WHEN TO USE EPOXY CEMENT When you need a strong rigid workable (e.g. sandable and/or paintable surface) adhesive, particularly for use on metal or hard plastic, epoxy is usually the best choice. Most epoxies dry with little running or shrinkage, and so are good for filling gaps. The major drawback to epoxies is that they consist of two parts (resin and hardener) which must be mixed in small batches, and then applied with your own applicator (e.g., a toothpick or popsicle stick). Some are packaged in a dual-syringe--but that is not an adequate solution, because the components must still be manually mixed in order harden to maximum strength. WHEN TO USE JB-WELD JB-Weld is a very strong epoxy cement. JB-Weld is the cement/glue of choice when joining metal parts or filling holes in metals. Otherwise, ordinary epoxy cement or other types of cements/glues are usually better choices. Some other reviewers have complained that the descriptive name "weld" is inappropriate---to some extent that's true. JB Weld can do some jobs welding can't. Conversely some simple welding jobs like joining two thin metal rods at right angles are difficult with JB Weld. HOW TO USE JB-WELD General Principles: Although JB WELD makes an excellent filler---and can even be used to cast small parts, it is not remotely as strong as real metal used this way. Whenever possible, use JB WELD as an adhesive---a very thin layer of JB WELD holding two pieces of metal together. Always reinforce with metal pieces when possible. For example, rather than building up a massive flange with JB Weld, you might be able to use scrap peice of metal to form most of the flange, held in place with JB Weld. The greater the relative surface area of contact, the strong the bond will be. Surface Preparation: As with any adhesive, the surface must be clean and rough. Clean with a solvent (according to another reviewer, acetone is the best solvent for this purpose, but rubbing alcohol will work), roughen the surface, then clean with the solvent again. Use a clean cloth for each application of solvent. I generally use a small grinding wheel in a Dremel tool to roughen the surfaces. You can also scratch the surface with a knife, or use coarse sandpaper, or both depending on the material. The solvent cleaning is for removing the LAST TRACES of oil from CLEAN surfaces. If the parts are oily, even multiple cleanings with solvent may not be enough---you may redeposit oil from your cleaning cloth or as the solvent evaporates on the surface. So, if you can detect any oil on any portion of the part, or if you have any doubt, clean it with a degreaser first. If you do not have a commercial degreaser handy, a paste of laundry detergent and a stiff brush may do the trick. Only when you are certain that there are no traces of oil is it time for the solvent cleaning(s). Joining Broken Parts: If you are joining broken parts, with a clean but irregular matching surfaces, limit the roughening to scratching with a wire brush or etching with an acid (but be sure to wash off all traces of the acid). Apply a THIN uniform layer of JB WELD, lightly clamp together hard enough to squeeze out any excess. Sometimes a thick rubber band is perfect. Often you can arrange pieces so that the weight of the top piece will hold the joint together until the JB Weld cures. Sometimes you can place a weight (such as a brick) on top to apply gentle pressure. Do not remove the clamp or pressure until the JB Weld has cured completely. After an hour or two, after the glue has set but is still soft, you can cut off any excess with a knife or razor---but if you don't need to cut the excess off, don't. Often you can build-up the surfaces around a break for added strength. Sometimes blue painters tape can be used to help hold pieces together while the glue sets, and/or to make a temporary stand to hold the pieces in the best orientation. ScotchBlue Painter's Tape for Multi-Surfaces 2090-.75A, 3/4 Inches by 60 Yards, 1 Roll Joining Dissimilar Parts: Minimize any gaps if possible, e.g., by sanding if possible so that the contact as perfect as possible. If you will be filling substantial gaps, sometimes it is helpful to cover openings with blue painters tape to prevent the JB Weld from flowing away and leaving gaps. Joining Long Thin Parts (rods or sheets): Try to overlap if possible, or reinforce them with a similar overlapping peice of metal glued in place with JB Weld. To join a 1/8" steel rod, to another 1/8" steel rod, forming a "T" (a common and easy welding job, almost impossible with just JB-Weld), cut two 1"-long "L's" from a heavy-paper clip, (or make L's from similar wire), and embed those with JB-Weld on opposite sides of the joint. You can further strenthen the joint by wrapping fine steel wire around the rods holding the "L"s in place---before covering it all with JB-Weld. Be sure to thoroughly clean the rods and wires first (see below). For small parts, or when wire wouldn't work well, unwaxed dental floss is remarkably strong, and can do an excellent job of reinforcing joints (when embeded in JB Weld). Ideally, apply the JB Weld, then wind the floss tightly into the soft JB Weld. Filling Holes: Don't forget to prepare the surfaces as described above---even if you can only roughen the surfaces with an ice pick or awl. JB Weld shrinks very little as it cures so fill the hole completely. If it is possible to sand the surface when the JB Weld has hardened, then overfill the hole slightly. Since JB Weld flows a little until it sets, the surface should be horizontal. If not horizontal, you can apply the JB Weld and then cover the hole with blue painters tape until the JB Weld sets. Depending on the job, it is often a better strategy to fill the gap as much as possible with a piece (or pieces) of metal embedded in JB Weld that a single mass of pure JB Weld. Reinforcing a leaking pipe: Work JB Weld into a piece of fiberglass cloth or with a spatula, apply, and then add more JB Weld to any thin spots and to feather out the edges. You may have to apply several layers of the JB Weld-saturated fiberglass cloth. Sometimes wire cloth (window screening) can be used. Holes in car body panels etc: If you can cover at least one side of the hole with a piece of sheet metal (held in place by JB Weld) that is a good strategy---the combination of pop-rivets and JB Weld often works especially well, even if you ultimately sand the heads of the pop rivets away. TEKTON 6555 Rivet Gun with 40-pc. Rivets Mixing: Follow the instructions. A paper plate can be a good mixing surface; popsicle sticks are the best mixing tools. Beware that you must use the same amount of resin and hardener, and they MUST be VERY thoroughly mixed. Mix until you are certain that it is completely and thoroughly mixed, and then continue mixing for twice that time. Seriously!!! Curing: Follow the instructions, but wait longer than recommended: the longer you wait the stronger the bond. A a day or two at 70 or 80 degrees is a reasonable MINIMUM. Note that epoxies do not "dry"--there are no solvents to evaporate, instead a chemical reaction hardens the cement (a plastic resin). Chemical reactions are proportional to temperature (the rule of thumb is that for each 10 degrees, the reaction speed doubles). Using the rule of thumb, if it takes 1 day to cure at 80 degrees, then it takes 16 days to cure at 40 degrees, and that's only to minimally cured. Okay, I know that waiting this long is not practical in many circumstances---you can probably get away with curing for 4 hours at 90 degrees (but don't go much higher than 90 degrees), and "take it easy" for a couple of days. WHEN TO USE OTHER EPOXIES For materials other than metal, particularly for rigid plastics, other epoxies are usually better than JB Weld. Some epoxies are clear, or white, or specialized for particular purposes. For example CLEARBOND H-3S Clear Strong Epoxy Adhesive Syringe - .85oz WHEN TO USE QUICK-EPOXIES Ordinary (slow) epoxies (whether JB Weld or other epoxies) dry harder than quick epoxies and are generally the best choice. Maximum strength is the whole point of epoxies--if you don't need maximum strength---you probably do not need epoxy. Use quick epoxies when 1) the hardening speed is essential, 2) when the item cannot be supported in the required orientation while the epoxy sets (at least several hours), or 3) when you have to absolutely minimize flowage. Super-glue is often a good alternative in such situations. WHEN TO USE OTHER CEMENTS OR GLUES While epoxies are ideal for a few specific uses (primarily when you need a rigid cement for metal or rigid plastic)--there are many situations when other types of glue are better choices. Epoxies are generally NOT recommended for flexible surfaces, such as leather, wood, or flexible plastic, and generally do not adhere well to glass, etc. While epoxies may work with porous surfaces (paper, wood, ceramics, etc.), other adhesives are usually better. White Glue: For most light-duty indoor household applications which do not have to be waterproof, ordinary household white glue is safe, cleanup is very easy, and in most cases repairs are redo-able if you make a mistake. White glue shrinks a great deal as it dries, and so is not good for filling holes or large gaps. For example: Elmer's All Multipurpose White Glue, 7 5/8 oz. (E379) Glue Stick: Think of glue sticks as thick white household glue in stick form. Glue sticks are great with paper, but have few other applications. Avery Glue Stic, 0.26 oz, Pack of 6, (98095) Wood Glue: Carpenters's wood glue is essentially water-proof (when dry) white household glue. It penetrates and strengthens the wood better than any other type of glue. It is safe, and cleanup is easy. If the joint breaks again (because the wood is weak), it can be re-glued. For example: Elmer's E701 Carpenter's Wood Glue 8-Ounce Goop: Goop will bond virtually any material, including leather, plastics, glass, and metal. The bond is clear, VERY strong, waterproof, and hard but flexible. Since Goop is clear, if a little extra oozes out, it is barely noticeable. I've used Goop to repair ceramic plant pots, water hoses, and shoes; to seal holes in air-mattresses, to close small holes in window screens, as plumbers paste in assembling plumbing parts, to I also use it to seal rust spots on my dishwasher rack--the Goop it also makes a "cushioned" surface that will prevent scratches to dishes. Goop is particular good for repairing damaged electrical cords. Amazing Goop All-Purpose Household Goop, 3.7-Ounce Tube #130012 Silicon Glue: Silicon glue is best for glass, and when you want a truly flexible connection (for example, to absorb vibrations). It is a good alternative for Goop for general household use on glass, plastic, and metal when you do not need the maximum possible strength. It is safer than Goop, and cleanup is easier. Like Goop, silicon glue takes days to reach reasonable strength, weeks to reach maximum strength. For example: GE Silicone II Household Glue, 2.8 oz Fabric Glue: Beacon Fabri-Tac Permanent Adhesive, 4-Ounce works amazingly well on fabrics, saturating the surfaces enough to provide a very strong bond, but without soaking through. Depending on the application, fabric glue can be better than sewing. It remains very flexible, e.g., it would probably be great on leather or heavy vinyl (e.g., women's handbags, shoes, luggage, etc.) Super-Glue (Krazy Glue): Super-glue is very strong, rigid, and fast. In many ways it is similar to 2-minute epoxy---except that no mixing is required. Although very hard, super-glue is brittle, and so, is not recommended for flexible objects. Super-glue is hazardous in that it can easily glue fingers (etc.) together. Previously, I used super-glue frequently on objects (e.g., jewelry) when a clear bond was required---however, Goop is better for such applications, safer, and more conveneient. Opened super-glue keeps poorly, even in tighly sealed glass containers---so I recommended packages of multiple very small tubes. BAZIC Super Glue, 3 grams 0.10 ounces, 6 Per Pack Liquid Nails/Construction Adhesive: When you need to permanently join a large amount of surface, of almost any kind, Construction Adhesive is usually ideal. If you need to join 2 2x4s to make a 4x4 Construction Adhesive is better than nails. Most construction adhesives are slightly flexible, and so can even be used on leather (i.e., to repair a loose shoe sole), etc. Construction adhesive may leave a stain on porous surfaces, and may stain-through thin surfaces. For small projects, Goop is usually a better choice. Caulking Compound: You can think of caulking compound as white household glue with alot of inert filler--to use when you need to fill holes. As an adhesive, it is the weakest on this list, but is strong enough for many purposes when spread over a large surface, such as the back of a ceramic tile. A few years ago, I made a brick column to support a mailbox. Traditionally, I should have used mortar--which would have been very time consuming. I could have used construction adhesive (albeit any excess that squeezed out would have been ugly)--but caulking compound was quick, cheap, looks good, and was more than adequate for the job. Hot Glues: In short, if you really need the glue to set quickly, particularly if you've got alot of gluing to do -- consider hot glues. As several commenters have pointed out, there is a whole world of hot glues (which come in the form of glue sticks which are used in glue guns), many of which work better, or are more convenient, than comparable cold glues. In general, the most important attribute of hot glues is that the glue sets very quickly --- in some cases -- within seconds.. Since most hot glues set quickly, it is tempting to apply them too thickly. Even with hot glue, for maximum strength, you should use the smallest amount that does the job, and apply moderate pressure until the glue sets. Unfortunately, I have only limited experience with hot glues, and cannot supply specific suggestions for specific purposes.
