Foster® MONOLAR® mastic 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 retarder for low-temperature insulation on tanks, pipework, ductwork, vessels and fittings. MONOLAR® mastic provides outstanding weather barrier protection, showing good color retention, excellent chemical resistance and durability. MONOLAR® mastic trowels easily and smoothly without drag or excessive stringing. It features higher volume solids than some other vapor retarder mastics, reducing the number of gallons that need to be applied. MONOLAR® mastic is produced under the classification and follow-up service of Underwriter’s Laboratories, Inc.
