SCS1200 Construction sealant is a proven, high-strength, acetoxy-cure silicone designed for glazing applications.

100% silicone with exceptional strength and a fast cure time, it is ideal for butt joint, structural, and general glazing.

SCS1200 is proven in protective glazing applications and in adding stiffening elements to glass and building panels - securing glass to the frame without a primer, forming a seal that will not crack, shrink or separate.

It can be used without a primer on most nonporus construction materials, substrates and finishes, including glass, glass coatings, polycarbonate, vinyl, plastics, ceramic frits, fluoropolymer and powder coated paints, conversion coatings, and anodized aluminum.

SCS1200 Construction sealant is backed by world-class technical support and our extended limited material warranty.
