3M 2-component adhesive sealant applicator 400A-2K is a simple-to-use system designed to smoothly dispense an optimally mixed and accelerated polyurethane adhesive sealant. This pneumatic applicator is used with 550FC and AC63 sausage packs. While the curing of traditional polyurethanes relies on time and moisture, curing from the inside out, the 2-component, accelerated system of the 3M 2-component adhesive sealant applicator 400A-2K cures from the inside out in order to reach handling strength faster. Neither ambient moisture nor temperature is a factor and no exothermic reaction takes place. In the 3M industrial adhesives and tapes division, they apply the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, their technologies help customers like you deliver competitive products to the market faster and more efficiently.
