3M™ 7100062120 550 Adhesive Sealant, 45 mL Sausage Pack Container, Clear, Polyurethane Base

3M™ polyurethane adhesive sealant accelerator AC63 is a liquid additive that, when combined as a part of a two component adhesive system, accelerates the curing of the adhesive. It is capable of drastically reducing the handling time of adhesives used in highly productive construction settings. 3M™empowers its customers by designing the solutions that bring optimal performance to their everyday applications. We designed 3M™ polyurethane adhesive sealant accelerator AC63 for large applications where adhesive strength and cure time are factors. When this adhesive accelerator is combined with an adhesive in a two part adhesive system, it is capable of reaching full strength in a fraction of the time it takes conventional, one part polyurethane adhesives. Consistent, guaranteed cure rates can be achieved in less than an hour, while a tack free state can be achieved within 15 (+/-5) min. With a curing process unlike that of the one part polyurethane adhesives on the market, our two part accelerated polyurethane mixture of 3M™ polyurethane adhesive sealant accelerator AC63 and 3M™ polyurethane adhesive sealant 550 is capable of curing due to a chemical process as well as a moisture based process. This process actually cures the adhesive from the inside out, resulting in a more consistent cure that reaches full strength in a fraction of the time. No exothermic reaction takes place, no priming is required (for most applications) and the adhesive mixture does not stain.
