1. Product Overview

TSE388 is a one-component, oxime-cure, flowable silicone adhesive sealant that cures at room temperature via moisture in the air. It has a pourable consistency and provides excellent primerless adhesion to metals, plastics, ceramics, glass, and other substrates. The product offers neutral cure characteristics, minimizing the risk of corrosion, and demonstrates excellent resistance to high and low temperatures (–55°C to 200°C), weathering, ozone, chemicals, and electrical stress. Its single-component formulation makes it easy to use in industrial and electronic applications.


2. Applications

  • Waterproof sealing and potting for electrical and communication equipment

  • Airtight seals for meters to prevent water and dust ingress

  • Sealing and potting for equipment requiring thermal resistance

  • Coating for electronic components, integrated circuits, and semiconductors

  • General adhesion for metals, glass, plastics, wood, etc.
