Main features

Tough Impact Resistant Assembly
Rapid Non Sag Placement
Primed Multi Material Bonding

Product Description

3M Scotch-Weld Urethane Adhesive EC-3532 B/A is a two-part polyurethane adhesive that cures at room temperature or with heat to form tough, impact-resistant bonds. It adheres to many primed or painted metals and selected plastics, while the mixed material becomes non-sag in approximately 30 seconds for controlled placement on vertical or irregular joints. Equal-volume mixing and a 5 to 15 minute work life at 24 deg C support practical alignment before fixturing. After cure, prepared aluminum overlap shear reaches 2200 psi at 24 deg C and 2500 psi at -40 deg C.

Key features

Tough Impact Resistant Bonding: The cured polyurethane supports assemblies exposed to shock and service movement.
Rapid Non Sag Control: The mixed adhesive resists sagging in approximately 30 seconds.
Primed Metal And Plastic Adhesion: The urethane bonds many compatible primed or painted substrates.

Applications

Bonding primed or painted metals, selected plastics, and industrial or aerospace assemblies requiring tough, impact-resistant joints.
