Tough, flexible bonds can be achieved through 3M™ Scotch-Weld™ Urethane Adhesive 640, a two-part urethane adhesive. This urethane adhesive features non-sag and shear thinning properties for precise handling. Its long work-life (40-60 minutes) allows time for adjustments during the application process. In addition, 3M™ Scotch-Weld™ Urethane Adhesive 640 is formulated to have low viscosity for easy dispensing. This adhesive has a 1:1 mix ratio and reaches handling strength in approximately 8 hours, providing good adhesion to many substrates, especially wood and many properly abraded and cleaned plastics. 3M™ Scotch-Weld™ EPX™ Plus II applicator and mix nozzles are required for dispensing (not included).
3M™ Scotch-Weld™ Urethane Adhesive 640 can be used across many industries and have a wide variety of application possibilities, such as:
Polyurethanes are a class of polymers generally noted for their flexibility when cured. Two-part polyurethane adhesives comprise two components designed to be mixed, like an epoxy adhesive. The isocyanate, generally the accelerator or hardener side, reacts with the polyol or resin side when mixed, curing more quickly than one-part, moisture cure polyurethane systems, and with no depth of cure issues.
Urethane adhesives will work on most common materials such as wood, metals, rubbers, cured epoxy, leather, tile and glass, many plastics, concrete and more. The versatility of urethane adhesives comes from its chemical components; different formulations result in different stiffness, cure speed, hardness and other properties. These 2 component polyurethane structural adhesives can cure to be relatively rigid or more flexible to meet a wide range of requirements. Urethane adhesives will maintain bond strength integrity through variable environmental factors such as temperature, moisture and chemical exposure.
