Foster® 30-36AF Sealfas® AF Coating (Fungus Resistant)
FOSTER SEALFAS ® COATING AF (Fungus Resistant)
FOSTER SEALFAS Coating 30-36AF is a specially formulated white, tough, washable, abrasion-resistant indoor coating for use over thermal insulation in areas where high humidity and elevated temperatures are a problem. It is designed to resist mold, fungus and mildew growth on its surface and protect the insulation system. It is also used as a lagging and a lap adhesive for canvas and glass lagging cloth where additional fungal resistance of the adhesive is required. It has excellent brushing characteristics, which will result in better coverage and more uniformly coated surfaces. It presents a neat white finish, and will not yellow or become discolored with age. The surface can be washed free of grease, oil, soot, and other dirt accumulation.
SEALFAS Coating 30-36AF provides a protective finish for insulation on air conditioning ducts and cold water piping when applied with canvas, glass cloth or 10x10 glass mesh embedded between two coats. For unfaced insulation or for exterior applications when relative humidity exceeds 75% for continuous periods a fungus resistant vapor barrier such as Foster 30-80AF or 60-95 is suggested.
SEALFAS Coating 30-36AF offers the same proven qualities of standard Foster Sealfas Coating 30-36 with the added benefit of excellent fungus resistance. It meet the performance requirements of MIL-A-3316C, Class 1, Grade A.
SEALFAS Coating 30-36AF meets NFPA 90A and 90B 25/50 requirements and is compatible with polystyrene and polyurethane foam insulations.
SEALFAS Coating 30-36AF meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 17 g/l, less water and exempt solvents.
SEALFAS Coating 30-36AF contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. Always test foil and paper facings for acceptable adhesion before using.
