Foster® Fibrous Adhesive 81-27™ is an incombustible adhesive formulated with sodium silicate. It is primarily designed for bonding calcium silicate and expanded perlite thermal insulation to both itself and non-porous surfaces. This adhesive provides exceptional adhesion, and ideal working characteristics, and ultimately forms a hard, incombustible film with a brittle texture.

Foster® Drion® Contact Cement 85-75 is a fast-setting, water-resistant adhesive for sealing the laps of vapor barrier jackets and is also used for bonding materials to a variety of surfaces in applications where immediate adhesion and high initial adhesive strength are required.
