Product Description
WACKER GM: Neutral Low Modulus Silicone Sealant
WACKER GM is a one-part, neutral-curing, low modulus silicone sealant designed for glazing and metal bonding applications. It cures at room temperature upon exposure to atmospheric moisture, forming a durable and flexible silicone rubber.
Product Overview
This sealant offers excellent adhesion without requiring a primer on most non-porous substrates, including glass, metals, and plastics. It is formulated to be non-sag and can be applied in a wide temperature range (+5°C to +40°C). The cured sealant remains flexible under extreme temperatures (-40°C to +120°C) and exhibits strong resistance to weathering and corrosion.
