Material Notes:

3M™ Scotch-Weld™ Urethane Adhesives are two-part, non-sag urethane adhesives. They feature tough, flexible bonds with good adhesion to a wide variety of substrates especially wood and many properly abraded and cleaned plastics. Good adhesion can also be obtained on etched aluminum as well as primed aluminum, steel glass. For maximum bond durability under moisture conditions, priming of glass and metal substrates is required.Information provided by 3M
