Foster® 30-36 AF
Foster® 30-36 AF is a high-performance protective coating specifically designed for insulated HVAC duct systems. After insulation is installed and covered with canvas or reinforcing fabric, Foster® 30-36 AF is applied as the final sealing coat to create an airtight and moisture-resistant finish. Its primary function is to prevent warm humid air from penetrating the insulation. This significantly reduces condensation (duct sweating), protects the insulation from moisture damage, improves energy efficiency, and extends the life of the HVAC system. In addition to its sealing properties, the coating contains antifungal protection that helps resist mould and fungal growth, making it ideal for hospitals, commercial buildings, clean rooms, pharmaceutical facilities, and other environments where indoor air quality is important. Applications: Chilled water HVAC duct systems Air-conditioning duct insulation Air Handling Units (AHUs) Commercial buildings Hospitals and healthcare facilities Pharmaceutical plants Food processing facilities Industrial HVAC systems Clean rooms Cold-air ventilation systems
