FOSTER Cryogenic Coating is a two-part, black, elastomeric coating designed for use in cryogenic applications as a vapor stop sealant. It is suitable for application to polyurethane foam, polyisocyanurate (PIR) foam, cellular glass, fibrous glass and aerogel insulations in conjunction with aluminum, steel, wood and masonry construction materials.

Cryogenic Coating has excellent resistance to moisture, water vapor and other gases. It is an excellent vapor stop material for use on cryogenic pipe lines and cryogenic equipment.

Cryogenic Coating is also suitable for bonding and sealing lap joints in plywood and metal and for lagging glass cloth to itself and other surfaces. It can function both as a vapor barrier and adhesive where at least one substrate is permeable to allow for solvent evaporation.
