Dowsil 995 Structural Silicone Sealant

Product Details

DOWSIL 995 Silicone Structural Sealant is a one-component neutral-curing silicone sealant designed specifically for structural bonding applications of glass and metal in factory or field situations.

The rate of surface cure and cure-in- depth of most one-component RTV silicone sealants is affected by the temperature and humidity of the environment. However, an environment of high temperatures in combination with high humidity may slow the surface cure rate of DOWSIL 995 Silicone Structural Sealant.

A one-component, self-priming, shelf-stable, neutral-cure, elastomeric adhesive specifically formulated for silicone structural glazing and exhibits excellent unprimed adhesion to most building substrates. This product has superior unprimed adhesion for structural glazing applications for hurricane or impact rated windows and doors. It has a movement capability of +/- 50%.

High ultimate tensile strength sealant ideally suited for structural bonding and protective glazing applications
