JB Weld Plastic Bonder vs Infinity Bond MMA 500
JB Weld Plastic Bonder and Infinity Bond MMA 500 are both two-part adhesive systems used for bonding plastics. The former is a urethane adhesive system, while the latter is a methacrylate adhesive system.
JB Weld Plastic Bonder is a quick-setting adhesive with a simple 1:1 mixing ratio that sets in 15 minutes. It provides strong, lasting repairs and can even bond many metals and concrete. It is an epoxy putty that was originally used in truck repair. While JB Weld Plastic Bonder is strong, it is not ideal for low surface energy plastics such as Polyethylene (PE).
Infinity Bond MMA 500, on the other hand, is a unique adhesive that can bond difficult plastics like Polyethylene (PE) and Polypropylene (PP) better than almost anything else on the market. It is a 1:1 two-part adhesive that requires a cartridge gun and static mixer for dispensing. Like most MMA adhesives, little to no surface prep is required before applying the adhesive. It has a 4-5 minute open time and will create a permanent bond with chemical adhesion, even to challenging plastics.
In a strength test conducted by Adhesive Systems Inc., polypropylene (PP), polyvinyl chloride (PVC), and aluminum samples were tested. The results showed that Infinity Bond MMA 500 performed better overall as a plastic bonding adhesive than JB Weld Plastic Bonder. While the PVC samples yielded similar results for both adhesives, the PP to PP and aluminum to PP samples showed considerably better results for MMA 500.
Another test conducted by Popular Mechanics involved gluing a 1/2-inch PVC pipe bonded end-to-end with JB Weld Plastic Weld. The sample was unbreakable by hand pressure but snapped off easily with a pair of locking pliers. This indicates that the bond was strong enough to withstand indoor applications, such as supporting a small sign.

JB Weld stronger than steel?
JB Weld is a well-known brand of epoxy adhesive that has been around since 1969. Epoxy adhesives are known for their strength and versatility, and JB Weld is no exception. The company's original product was a simple epoxy putty used in truck repair, but they now offer a range of products for various applications, including DIY projects, auto repairs, construction, and crafting.
So, is JB Weld stronger than steel? JB Weld's website makes a bold claim that their epoxy products are "tougher than steel" once they have set. They attribute this strength to the cross-woven pattern of the epoxy, which provides extra strength, much like rebar does to reinforce cement structures.
Independent testing of JB Weld's strength has shown that it can withstand significant force. In one test, a sample bonded with JB Weld only broke after being struck with a ball peen hammer, which is quite impressive. Another test involving a PVC pipe bonded with JB Weld showed that it could not be broken with hand pressure but snapped easily with a pair of locking pliers.
While JB Weld is undoubtedly strong, it is difficult to make a direct comparison to steel as they are different materials with different properties. Steel is a metal alloy known for its high tensile strength, while JB Weld is an adhesive with strong bonding capabilities. However, based on the available evidence, it can be said that JB Weld can create bonds that are incredibly strong and can withstand significant force.
Overall, JB Weld is a highly effective adhesive with exceptional strength. While it may not be accurate to say that it is "stronger than steel," it certainly provides a long-lasting and robust bond that can rival many other adhesives on the market. For projects requiring strong and durable bonds, JB Weld is an excellent choice.
