DOWSIL™ 983 Structural Glazing Sealant Base 55 Gallon Drum

Call for Pricing and Availability

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 aluminum, although DOWSIL™ Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.
