DOWSIL™ 983 Structural Glazing Sealant Base and Curing Agent
Designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum1, although DOWSIL™ Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.
Uses: - Structural and sealing applications for factory glazing and glass curtain wall production
Benefits: - Approved for structural and weatherseal applications
- Meets ASTM C719 Class 25 (G, A, O)
- Meets ASTM C1184 Structural Glazing Specification
- Low VOC formula (less than 18 g/L when mixed properly)
