FOSTER FOAMSEAL Sealant is a gray vapor barrier sealant designed for use with rigid thermal insultaiton including polystyrene foam. It remains flexible and tough in joints and will not shrink or crack during repeated cycles of high and low temperatures. FOAMSEAL Sealant seals the joints of cellular glass and other insulations against the entrance of moisture. When used as a bedding compound on iron or steel surfaces and as a joint sealant, 30-45 provides additional protection to the blocks of insulation. Damage to the insulation due to migration of moisture is minimized. FOAMSEAL Sealant is water and weather resistant and is often used as a sealant and flashing compound where structural parts must penetrate an insulation surface. FOAMSEAL Sealant meets the requirements of Military Specification MIL-B-19564. FOAMSEAL Sealant contains no asbestos, lead, mercury, or mercury compounds.
