1. Product Overview

TSE322 is a one-component, heat-curable silicone adhesive designed for electrical and electronic applications. It cures quickly under heat to form a tough silicone elastomer with excellent adhesion to a variety of substrates. Available in light blue (TSE322) and black (TSE322-B), it provides primerless adhesion, is non-corrosive to metals, and exhibits high thermal stability from -55°C to 200°C.


2. Applications

  • Sealing and bonding between plastics, metals, and ceramics in electronic parts

  • Adhesive for semiconductor modules, automotive electronics, and home appliance assemblies

  • Heat-cured silicone elastomer bonding
