Silicone Potting

One component adhesives

Our room-temperature vulcanized materials require no mixing or oven equipment to process. Instead, they draw moisture from ambient air to cure simply and cost-effectively. After cure, these materials form strong, but flexible bonds with proven performance in the most demanding applications.

dow Sealant

Dowsil’s Sealants

Flexible yet resilient, Dowsil’s silicone encapsulants cure with minimal shrinkage and involve no solvents or cure by-products, helping to maximize processing efficiency and minimize costs. After cure, they form strong but low-stress environmental seals that can be reworked and repaired easily. Specialty grades deliver excellent optical clarity, thermal conductivity, flame retardance or reliable performance from –45°C to 200°C.
