3M Scotch-Weld™ DP8010 Structural Adhesive
Categories:	Polymer; Adhesive
Material Notes:	3M™ Scotch-Weld™ Structural Plastic Adhesive DP-8010 is a two-part acrylic-based adhesive (10:1 ratio by volume) that can bond many low surface energy plastics, including many grades of Polypropylene, Polyethylene, and TPO’s with out special surface preparation. It can replace screws, rivet, plastic welding, and two-step processes which include chemical etchants, priming or surface treatments in many applications. Information provided by 3M
