DOWSIL™ 983 Structural Glazing Sealant

Overview

DOWSIL™ 983 Structural Glazing Sealant is designed for factory glazing and curtain wall production. It is suitable for use where dual structural and weatherseal applications are desired, with up to ± 25% movement capability in a well-designed weatherseal. Once cured, this structural sealant forms a durable, flexible and watertight bond. It has excellent unprimed adhesion to most glass, chromated and anodized aluminum and many painted aluminum surfaces. DOWSIL™ Primer-C may be required for fast and consistent adhesion to polyester powder coat and fluorocarbon coatings and other high performance coated substrates approved for architectural structural glazing applications.
