Dow Corning 995 Structural Silicone Sealant is a one-part, neutral-cure adhesive that is designed for use with most common building substrates such as glass, reflective glass, anodized aluminum, granite and paints, including most fluoropolymer-based paints.

“Dow Corning 995 sealant is particularly well-formulated for structural glazing applications and new impact-resistant protective glazing systems,” says Mike Blaszkowski, Dow Corning construction market manager. For example, it is used to protect the 2,559 windows of the CNA Financial Plaza Building in Chicago from the harsh impacts created from sudden atmospheric wind loads.

According to the supplier, Dow Corning 995 is the only approved sealant for the 3M Ultraflex System, and it meets the impact/hurricane structural glazing standards required for new construction in Dade County, Fla. and bomb blast requirements for new structural glazing systems. The product combines high tensile adhesion strength (150 psi) with superior tear strength (49 psi) and unprimed adhesion to most common building substrates such as glass, reflective glass, anodized aluminum, granite and paints, including most fluoropolymer-based paints.
