Foster® Cryolar™ 1K Vapor Stop Sealant 90-61 is a ready-to-use, one-component vapor stop sealant specifically designed for use in cryogenic applications. It is formulated with select synthetic rubbers to create an elastomeric vapor barrier film capable of spanning the temperature ranges encountered in cryogenic processes, including LNG, ethylene, and ammonia production. This sealant is suitable for application to various insulation materials like PUR and PIR foam, cellular glass, and other rigid insulations. It can be used in conjunction with aluminum, steel, and masonry construction materials.
