High-performance, one-component, neutral-cure silicone sealant with excellent adhesion to glass, aluminum, anodized metals, and common construction substrates.
Low modulus formulation provides superior joint movement capability (±50% joint movement per ASTM C719) and reduces stress on bonded substrates.
Non-staining, acetoxy-free cure chemistry eliminates risk of corrosion on sensitive metals and prevents discoloration of stone, marble, or coated surfaces.
Excellent weather resistance, UV stability, and long-term durability under extreme temperature and humidity conditions.
Meets stringent industry standards including ASTM C920 Type S, Grade NS, Class 50, and ISO 11600 F50HM.
Structural glazing systems for commercial façades and curtain walls.
Perimeter sealing of insulating glass units (IGUs) in windows and skylights.
Weatherproofing of aluminum composite panels (ACP), metal cladding, and architectural precast concrete joints.
Sealing of high-rise building expansion and control joints requiring long-term elastic performance.
Interior and exterior architectural glazing where non-corrosive, high-clarity, and low-volatile organic compound (VOC) performance is required.

Q1: What substrates is DOWSIL SE 760 SG compatible with?
A: DOWSIL SE 760 SG adheres well to common construction and architectural substrates including glass, anodized aluminum, painted metal, ceramic tile, and many coated or primed surfaces. Surface cleanliness and proper preparation—such as removal of dust, oil, and release agents—are critical for optimal adhesion.
Q2: Is DOWSIL SE 760 SG suitable for structural glazing applications?
A: No—DOWSIL SE 760 SG is a high-performance silicone sealant designed for general-purpose sealing and weatherproofing, not for load-bearing structural glazing. For structural applications, Dow offers dedicated structural silicone sealants such as DOWSIL SE 910 or SE 917, which meet ASTM C1184 and other relevant performance standards.
Q3: How does temperature affect the cure speed of DOWSIL SE 760 SG?
A: Cure speed increases with higher ambient temperature and relative humidity. At typical conditions (23°C and 50% RH), surface tack-free time is generally achieved within 30–60 minutes, and full cure progresses over several days. Lower temperatures or dry environments will extend cure times significantly.
Q4: Can DOWSIL SE 760 SG be painted after curing?
A: Most conventional paints—including acrylics, alkyds, and epoxies—are not recommended over cured DOWSIL SE 760 SG due to potential adhesion failure or surface incompatibility. If painting is required, compatibility testing under actual application conditions is strongly advised prior to full-scale use.
