Product Introduction
SILTRUST TSE3331 is a two-component, heat curable silicone rubber
for electic and elecronic poting. It cures with heat to form
elastic, fame retardant rubberand adheres to various types of
materials without the need for primers, such as metals, plastics,
glass and ceramics.
Advanced Properties
Convenient 1:1 mix ratio by weight
Excellent thermal conductivity
Low viscosity allows for excellent flowability
Excellent adhesive properties: primerless adhesion to many types of
substratesFlame retardant: UL94V-0 recognized (File No: E56745)
Resistance to temperature extremes
Non-corrosive to most metals
Application Scenarios
- High-voltage component potting: e.g., power modules and
transformers, leveraging its dielectric strength (26 kV/mm) and UL
94 V-0 rating
- PCB moisture-proof coating: Low viscosity ensures complete
coverage against humidity
- Automotive electronics: Withstands -50~200°C for engine
compartment components
- Consumer electronics sealing: Biocompatibility suits seals for
wearables
