Foster® 40-20™ Fungicidal Protective Coating
Foster ® 40-20 TM Fungicidal Protective Coating (40-20)is a polyacrylate copolymer emulsion specifically formulated for long-term fungicidal activity, with no loss of activity on aging. It is formulated to effectively prevent the spread of molds and odor-causing bacteria on its surface. It provides a tough, elastic, decorative finish that allows for movement without splitting and creating lodging places for bacteria.
Foster 40-20 provides a cost effective decorative finish resistant to many industrial chemicals, together with long-lasting protection. It can be used on walls, ceilings, pipes, interior and exterior surfaces of HVAC duct systems, and wherever effective controls are essential.
Foster 40-20guards against the re-growth and spread of odor-causing bacteria and molds on the surface of the coated HVAC system or its treated components only. As a result, the building occupants may enjoy a work space free of the odor problems often associated with contaminated HVAC duct systems.
Foster 40-20 meets requirements for LEED ® EQ Credit 4.2, low- emitting materials: paints and coatings. VOC: 42 g/l, less water and exempt solvents.
Protect from freezing. Do not apply near food stuffs in unventilated areas. Always ensure adequate ventilation. Do not store or apply over 100ºF (38ºC) or below 40ºF (4.4ºC). Water-based products may corrode carbon steel spray equipment. Corrosion resistant pumps and fittings are suggested.
DO NOT DILUTE.
