Foster® 95-44 ELASTOLAR® Sealant
FOSTER ELASTOLAR ® SEALANT
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 aluminum jacketing to prevent the entrance of moisture.
ELASTOLAR ® Sealant is a fast drying vapor barrier sealant that can be top coated with most solvent-thinned, 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.
ELASTOLAR ® Sealant meets NFPA 90A and 90B 25/50 requirements.
WATER VAPOR PERMEANCE: ASTM F-1249: 0.014 perm (0.0092 metric perm) at 0.094 in. (2.38 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.
ELASTOLAR ® Sealant contains no asbestos, lead, mercury, or mercury compounds.
ELASTOLAR ® Sealant may meet requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants for some applications where the use falls under the `Other' category. Refer to LEED guides for more information. VOC: 384 g/l, less water (336 g/l, less water cartridge grade)
Store and apply between 40°F and 100°F (4°C and 38°C). Always test plastic materials for compatibility when using a solvent base product. When used in exposed locations without top-coating, this product may darken or discolor due to surface dirt pick-up. This will not affect its performance. Make certain this product is completely dry and the area is free from solvent odor if food is involved. Select Foster 30-45N for joint sealing polystyrene foam insulations.
