Product Introduction
3M™ Scotch-Weld™ Urethane Adhesive EC-3535 B/A is a fast-acting, two-part urethane adhesive that forms tough, high-impact structural bonds. It cures at room temperature or with heat, providing strong adhesion on metals, plastics, composites, and painted substrates. The adhesive becomes non-sag about 30 seconds after mixing for easy handling, with a 3-5 minute work life for precise application. It offers a flexible and durable alternative to mechanical fasteners.
3M™ EC-3535 B/A Features
- Two-component, urethane adhesive cures at room temperature for convenient, easy use
- High impact resistance helps improve service life and reduce potential damage
- Excellent adhesion to many primed or painted metal and plastic substrates minimizes prep
- Designed to develop sag resistance approximately 30 seconds after mixing to keep processes moving
- 3-5 minute work life and 8-hour cure time provide fast results
3M™ EC-3535 B/A Applications
- Structural bonding of metals, plastics, and composites
- Adhesion to primed or painted metal and plastic substrates
- High-impact applications requiring flexibility and toughness
- Aerospace and industrial bonding processes requiring sag resistance
- Situations requiring fast handling strength and room temperature curing
