Foster® 90-66 Cryogenic Coating
FOSTER CRYOGENIC COATING
FOSTER Cryogenic Coating is a two part black elastomeric coating designed for use in cryogenic and specific chemical resistance applications. It is suitable for application to polyurethane foam, polyisocyanurate (PIR) foam, cellular glass and fibrous glass insulations in conjunction with aluminum, steel, wood and masonry construction materials.
Cryogenic Coating has excellent resistance to moisture, water vapor and other gases. It also has good resistance to most oils, mild solvents, inorganic acids, inorganic bases and salt solutions.
Cryogenic Coating is 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 in very low temperature applications where a water vapor tight insulation system is required. It is an excellent vapor stop coating material.
Cryogenic Coating contains no lead, asbestos, mercury, or mercury compounds.
Store and apply between 40°F (4°C) and 100°F (38°C). Always test plastic materials for compatibility when using a solvent base product. Make certain this product is completely dry and the area free from solvent odor if food is involved. Not suggested for application between two impermeable surfaces, or as an exposed finished coating for extended periods of time. TM TradeMark of HB Fuller Construc tion Products Inc.

BONDING TIME RANGE:
POT LIFE (FSTM 91A):
(Varies with temperature) 6-9 hours @77°F (25°C)
DRYING TIME 73°F (23°C) 50% RH:
Temperatures below 70°F (21°C) and adhesive applications prolonging dry time will require longer cure times. Through: 48 hours Full Cure: 2 weeks
