DOWSIL™ 3-7509 Silicone Sealant Black is intended for use as a secondary sealant in a dual-sealed insulating glass unit (see Figure 1). A primary seal, typically polyisobutylene, is required to prevent moisture vapor from transmitting into the airspace of the insulating glass unit. Dow Corning 3-7509 Silicone Sealant can bond the individual components, forming a weather-resistant unit capable of being certified to a CBA rating by an independent test laboratory in accordance with industry standards.
