Product Description
Momentive TSE3971 is a one-component, fast cure, non-corrosive silicone adhesive sealant that cures on exposure to atmospheric moisture to form an elastic silicone rubber. TSE3971 has a pourable consistency and excellent corrosion-free adhesion to metals, including copper, plastics, ceramics, glass, etc without the use of primers.
Key features of Momentive TSE3971
♦ Non-corrosive to metals: meets MIL-A-46146B corrosion test
♦ Fast cure
♦ Low odor; releases an alcohol vapor during cure
♦ Primerless adhesion to many substrates
♦ Pourable consistency: higher viscosity than TSE397 (50Pa·s)
♦ Excellent high and low temperature resistance: from -55°C to 200°C
♦ Excellent weatherability, ozone, and chemical resistance
♦ Excellent electrical insulation properties
♦ Simple and easy-to-use one-component system
Applications of Momentive TSE3971
♦ Insulating seal for electrical and electronic parts
♦ Coating for hybrid ICs
♦ Waterproof sealant for electrical, electronic and communication equipment
