Foster® 90-66 is a two-component elastomeric adhesive and surface coating product specifically designed for use in cryogenic applications. It is suitable for application to aluminum, steel, wood and wall construction materials as well as polyurethane foam, foamglass and fiberglass insulations.

Foster® 90-66 has excellent resistance to moisture, water vapour and other gases. It also has good resistance to most oils, mild solvents, inorganic acids, inorganic bases and salt solutions.

Foster® 90-66 is suitable for bonding and sealing lap joints in plywood and metal, and for adhering fiber glass cloth to itself and other surfaces. It can function both as a vapour barrier and adhesive in very low temperature (cryogenic) applications where a vapour tight insulation system is required.

Foster® 90-66 contains no asbestos, mercury, or mercury compounds.
