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.
- Good unprimed adhesion to uncoated glass and aluminum
- Single component formulation, minimizing waste and downtime by eliminating base purging and static mixer maintenance
- Consistently non-slump, permitting automated glazing
- Excellent shelf life stability
- Easy tooling
