Description

DOWSIL™ 983 is designed for specialised 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 anodised aluminium, although DOWSIL Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.

Produced in compliance with the internationally recognised PAS 2060 verified carbon neutrality standard, Dow Carbon-Neutral Silicones for Building Façades can support green-building design initiatives, enhance façade sustainability, and improve green-building ratings across the construction industry.
