Description
FOSTER Elastoral Sealant 95-44 310ml USA
FOSTER® ELASTOLAR® Sealant is a fire-resistive, flexible, butyl elastomer-based, vapor barrier sealant. It is designed for sealing joints in insulation (except polystyrene foam), metal and masonry wherever maintenance of a water-tight and air-tight seal is required. It can be used as a joint sealant in low-velocity duct air-conditioning systems. It is ideal for sealing the laps of metal jacketing to prevent the entrance of moisture. ELASTOLAR® Sealant is a fast-drying, vapor barrier sealant that can be top coated with most solvent-based, flexible, light-colored coatings without danger of bleed-through. It is weather resistant and may be used outdoors without top coating. ELASTOLAR® Sealant is the preferred product for flashing projections and terminations where a complete moisture and vapor seal is required. WATER VAPOR PERMEANCE (TYPICAL AVERAGE): ASTM F1249: 0.02 perm (0.013 metric perm) at 0.080 in. (2.0 mm) dry film thickness. Tested at 100°F (38°C) and 90% RH The water vapor transmission through 1 in. of impermeable insulation in 12 x 18 in. blocks with 1/8 in. joints of ELASTOLAR® sealant is too small to measure. |
