J-B Weld PlasticWeld Plastic Repair Epoxy - 2 oz

Easy to use, great strength

I have some cycle mirrors that broke on the stalk. Have used super glue and gorilla glue which had to keep regluing every month. Bought this and so far it has proven really good. All still holding together and firm. No signs of the glue deteriorating. Left the glued mirror to set for a few days. It's quite sticky, even after 24 hours. As there is a lot of vibration going through the mirror, I wanted to ensure the glue was properly cured before using. Shame I hadn't discovered it a year or so ago. I've hardly used any of it. Glad I bought it.

This epoxy based adhesive is just the thing for repairing those little mishaps thet can sometimes come about with thin plastics and bodywork found on most modern (and older) Japanese motorcycles such as cracked panels and broken tabs on fairings and side panels. It cures to form a solid and dependable repair on most applications but the claim of setting within 5 minutes has to be taken with a pinch of salt, as does the 1 hour full cure time. It has to be taken into account that environmental conditions affect the curing times of any Epoxy resin based adhesive and that colder conditions mean the curing times are slowed considerably and that curing times indoors and in warmer weather will be accelerated. The dispensing tubes are perfect for giving just the right amount of adhesive and hardener to get a good mixture and the cap ensures there is no waste or spillage providing you re-fit it promptly after use. I did find that, once mixed, the adhesive was quite runny and overflowed the joint but it's easy to wipe any excess off while it's still runny. It also took longer than the 5 minutes claimed (Closer to 10 minutes) to set during which time, you have to hold the joint together or support it to stop it coming apart, But this does mean you have some time to re-position parts before it sets fully if you have to. But for these details it would have scored a full 5 stars, but to do that, It has to do what it's claimed to do and unfortunately, there isnt a four and a half star option.

All good I recommend

Repaired my plastic ABS motorcycle mudguard also the corner of my laptop after dropping it. Its very strong, once glued I could bend the mudguard by the broken piece without it coming apart. when fully dry after 24hrs it can be filed or sanded. The mixing tubes are great and do not block at all. Try and "key up" the surface to be glued with fine sandpaper. At £6.75 its really good value.

Not great

Lots said that it takes an hour to cure. Said that on the box, 5 mins working time. Fantastic glue, bike fairing is fixed

This stuff is hopeless and I really don’t know how it attracts any good reviews. It fails spectacularly with plastic. Tried to repair a wheelie bin lid, no chance. Recently the dog’s ball thrower, fail. It stays runny far too long, it’s meant to develop strength after 5 minutes. Once set it hasn’t developed any strength anyway. Never sets to a reasonable hardness. Back to Araldite for me which has always worked. Only tried jb weld as it’s so well marketed and over hyped. More fool me. Update. Tried Araldite and superglue and both failed. But at least araldite says on the packet it’s not suitable for polyurethane and polycarbonate which I guess is what the thrower is made of. You might expect something advertised as plastic weld could glue all the common plastics.

habe damit schon einiges geklebt und restauiert wie z.B. das Kunstoffinnenleben eines 2005er Furbys

Joa was soll man sagen. Der Kleber härtet einfach nicht aus. Nach einem Tag ist er zwar fest, aber immernoch weich. und nach einer Woche ist er oberflächlich hart aber darunter immernoch nicht hart. Es wurde exakt auf ein 1:1 Verhältnis geachtet und gut durchgemischt. Würde ich nie wieder kaufen. Geldverschwendung.
