Detailed Photos
SV 8890 Silicone Insulating Glass sealant is intended for use as a secondary sealant in a dual-sealed insulating glass unit. A primary seal, typical being a polyisobutylene mastic, is required to prevent moisture vapor from transmitting into the airspace of the insulating glass unit.
