Dow Corning 983 Two Part Structural Silicone
Mixed DOWSIL 983 Structural Glazing Sealant is a two-part silicone formulation. As supplied, the base is a smooth, white paste and the curing agent is a dark grey paste. Once catalysed, the material cures to a high-modulus, flexible silicone rubber that is suitable for use in structural and weather-seal applications.
DOWSIL 983 Structural Glazing Sealant features excellent adhesion to most common construction materials, a physical property profile that is more than sufficient for structural adhesive and weather-seal applications, a non- corrosive by-product, and excellent weather-ability, durability and recovery after repeated extension and compression up to 25%.
DOWSIL 983 Structural Glazing Sealant is compatible with reflective glass, laminated glass and most insulating glass. It can be used in deep narrow joints to obtain a full cure.
