S996

S996 Silicone Sealant

S996 silicone sealant is a neutral one-component moisture-curing sealant with high modulus and both sealing and elastic bonding properties. It is suitable for elastic sealing of butt joints and lap joints of various materials, as well as for bonding light board and small accessories. The curing speed of S996 is affected by ambient temperature and humidity. It hardens faster at high temperature and high humidity, and cures slower obviously at low temperature.

Advantage

√ Neutral curing, no corrosion for base materials (except copper).
√ Free of toxic solvents, environment-friendly and safe.
√ Low shrinkage and beautiful rubber molding.
√ Excellent weather resistance, UV resistance, withstanding harsh natural weather conditions.
