3M™ Scotch-Weld™ Metal Primer is a primer designed for applications using 3M™ Scotch-Weld™ Structural Adhesives. This film and liquid adhesive primer is able to improve metal and glass adhesion. Additional features of this primer include improved corrosion protection and resistance to environmental exposure for metal.3M Scotch-Weld Metal Primer is a one-component, metal and glass primer designed for use with 3M Scotch-Weld Film and Liquid Structural Adhesives. Formulated to improve metal and glass adhesion, this film and liquid adhesive primer simplifies production scheduling by protecting the cleaned surfaces until the bonding operations can be completed. This product also offers resistance to environmental exposure and also provides improved corrosion protection to metal. 3M Scotch-Weld Metal Primer 3901 features low viscosity for ease of application and ensures complete wetting of the film adhesive to adhered surfaces, providing an ideal application surface. For those applications using 3M Scotch-Weld Structural Adhesives, 3M Scotch-Weld Metal Primer ensures that surfaces remain relatively free of oxidation until the bonding application is completed. Protection from and resistance to corrosion and environmental exposure is key to successful, long-lasting adhesion.
