Foster® MONOLAR® II MASTIC based on chlorosulfonated polyethylene rubber (formerly known as Hypalon®) is a tough, flexible, fire-resistive, elastomeric finish for protection of thermal insulation. It is also used as a vapor retarder finish for fittings. It is excellent for outdoor use where good color retention, chemical resistance and durability are required. MONOLAR® II MASTIC provides outstanding weather barrier and vapor retarder protection for most board stock thermal insulations except polystyrene. It normally bonds well to aluminum foil facings, but a test application is recommended to confirm adhesion. MONOLAR® II MASTIC is produced under the classification and follow up service of Underwriter's Laboratories, Inc. MONOLAR® II MASTIC meets NFPA 90A and 90B 25/50 requirements.
