Product Description
The main components of single component epoxy adhesive include epoxy resin base material, curing agent, diluent, and accelerator. It can be used directly without mixing. This adhesive offers convenience, excellent performance, fast curing speed, and wide adhesion. It features high adhesion strength, a simple process, small curing shrinkage, good fatigue resistance, and contains no volatile solvents, making it low harm to the environment.
Model 3621 is a grey, solvent-free, one-component epoxy structural adhesive. This product has good toughness and impact strength. When fully cured by heat, it provides excellent bonding properties, electrical properties, moisture resistance, and mechanical properties. It has high bonding strength to most substrates including glass, metal, and ceramics. It meets performance requirements under high temperatures and is widely used in automotive electronics, pressure sensors, wire harnesses, and motor magnetic sheet bonding.
