Best Practices for 3M 3750
-
Application
3M™ Scotch-Weld™ Hot Melt Adhesives 3750 Clear and Light Tan are designed for applications using the 3M™ Scotch-Weld™ Hot Melt Adhesive Applicator (1/2" x 10") AE II.
Apply adhesive to one surface. Make bond as soon as possible. Bond strength is maximized when open time is reduced.
After the bond is made, there is immediate handling strength and no clamping is necessary.
