Product Description
3M Scotch-Weld Structural Adhesive EC-3587 B/A Gray is a gray, two-part polyurethane structural adhesive available in B-1/4 and B-1 work-life classes. It cures at room temperature or with heat to a tough, impact-resistant material that bonds many prepared metal and plastic substrates. The non-sag mixture also functions as a void filler or fairing compound and can be sanded after cure. Class B-1/4 provides 5 to 20 minutes of work life, while Class B-1 provides 40 to 150 minutes at 23 deg C for different part sizes and placement windows.
Key features
- Structural Bonding And Fairing: One material can bond, fill gaps, and form a sandable fairing surface.
- Selectable Work Life Classes: B-1/4 and B-1 versions provide different application windows.
- Tough Non Sag Urethane: The mixed adhesive holds its shape and cures to an impact-resistant material.
Applications
Structural bonding of prepared metals and plastics, void filling, gap filling, and sandable fairing work.
