3M Scotch-Weld Urethane Adhesive EC-3532 B/A is a two-component polyurethane adhesive that cures at room temperature or with heat to form tough, impact-resistant structural bonds. It provides excellent adhesion to many primed or painted metal and plastic substrates and becomes non-sag approximately 30 seconds after mixing. 3M Scotch-Weld Structural Adhesive Primer EC-3901 is suggested on metal surfaces for maximum resistance to water, humidity and salt spray.
Features
- Mix ratio base : accelerator = 100 : 109 by weight, 1:1 by volume
- Work life 5–15 minutes (100 g at 24 °C); full cure in 24 hours
- Non-sag approx. 30 seconds after mixing; brown when cured
- Tough, impact-resistant structural bonds
Applications
- Bonding primed or painted metals
- Bonding plastics
Notes
- The EC grade is labelled, packaged, tested and certified for aircraft and aerospace applications; 3532 B/A is identical in chemical composition (3M Aerospace catalogue).
- Surfaces must be dry and free of rust, oil, grease and wax; abrade and solvent-wipe before bonding.
