FOSTER MONOLAR Ⅱ MASTIC (F60-38/39)
FOSTER MONOLAR Ⅱ Mastic based on DuPont Hypalon* is a tough, flexible, fire-resistive elastomeric finish for protection of thermal insulation. It is also used as a vapor barrier 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 barrier 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 meet NFPA 90A and 90B 25/50 requirements and contains no asbestos, lead, mercury, or mercury compounds.
