3M Scotch-Weld™ DP8005 Translucent Structural Adhesive
Categories:	Polymer; Adhesive
Material Notes:	3M™ Scotch-Weld™ Structural Plastic Adhesive DP-8005 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 without special surface preparation. It can replace screws, rivets, plastic, welding, and two-step processes which include chemical etchants, priming or surface treatments in many applications. Information provided by 3M
