KingSeal SN200®
One component neutral cure high modulus elastomeric silicone weatherproof sealant with mould resistance
Overview
KingSeal SN200 is a one-part neutral cure, high modulus, non-sag, elastomeric joint sealant which can be used internally and externally. KingSeal SN200 cures on exposure to atmosphere to form a firm but flexible rubber. KingSeal SN200 does not need primer when applied on non porous surfaces including solid concrete, aluminum or glass. Based on full cure, KingSeal SN200 can be used under submerged conditions.
