Foster 90-61 Cryolar 1K Vapor Stop Sealant

FOSTER Cryolar 1K Vapor Stop is a ready to use, one component, vapor stop sealant for use in cryogenic applications. It is specially formulated with select synthetic rubbers to form an elastomeric, vapor barrier film capable of spanning the temperature ranges found in cryogenic applications including LNG, ethylene and ammonia production It is suitable for application to PUR and PIR foam, cellular glass and other rigid insulations in conjunction with aluminum, steel and masonry construction materials.

Cryolar 1K Vapor Stop has excellent resistance to moisture and water vapor, forming a vapor tight seal from the cryogenic pipe surface to the ambient outer insulation surface.

Cryolar 1K Vapor Stop is designed for vapor stop applications on insulated cryogenic pipelines and equipment. It can also be used on very low temperature applications to seal seams where a water vapor tight insulation system is required.

Cryolar 1K Vapor Stop contains no lead, asbestos, mercury, or mercury compounds.
