TSE3940 and TSE3941 are one-component, fast-curing, flame-retardant silicone adhesive/sealants that cure upon exposure to atmospheric moisture, forming soft elastic silicone rubbers. They are non-corrosive to metals, retain elastomeric properties across a wide temperature range (-55°C to 200°C), and are ideal for electrical and electronic applications. TSE3940 is gray and UL94 V-0 rated, while TSE3941 is white and UL94 V-1 rated. Both provide outstanding adhesion, electrical insulation, thermal resistance, and environmental durability.
Electrical and electronic sealing and bonding
Protection against mechanical and thermal shock
Moisture protection for electrical components
Applications requiring flame retardancy and primerless adhesion
