Foster® 60-95 / 60-96 MONOLAR® COATING
FOSTER ® MONOLAR ® COATING
FOSTER MONOLAR Coating is a tough flexible fire-resistive elastomeric finish for protection of outdoor thermal insulation. It contains chlorosulfonated polyethylene rubber (formerly known as Hypalon ® *). It is an excellent vapor barrier for low temperature insulation on tanks, pipework, vessels, ductwork, and fittings.
MONOLAR Coating provides outstanding weather barrier protection, showing good color retention, excellent chemical resistance, and durability. It has excellent resistance to UV and sunlight.
MONOLAR Coating provides outstanding weather barrier and vapor barrier protection for sprayed polyurethane foam in outdoor locations. It is a one-component, high film strength product, usually applied in two coats with standard airless spray equipment. It sprays easily and cleanly with a minimum of cobwebbing.
MONOLAR Coating is an ideal finish for flexible cellular insulation tubing and sheets. Apply by brush in two coats.
MONOLAR Coating is produced under the classification and follow-up service of Underwriter's Laboratories, Inc.
MONOLAR Coating meets NFPA 90A and 90B 25/50 requirements.
MONOLAR Coating contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC). For best results, select ElastolarTM 95-44 for insulation joint sealing under Monolar coating. Always test plastic materials for compatibility when using a solvent base product. Outdoor horizontal surfaces must always drain completely. A pitch of at least 1/2" per foot (4 cm/m) is recommended. Make certain this product is completely dry and the area free from solvent odor if food is involved. Select Monolar Mastic 60-90 (white) or 60-91 (gray) for trowel or glove application. * Chlorosulfonated polyethylene rubber is also known as Hypalon, a trademark of Dupont Performance Elastomers, and is no longer produced by Dupont.
