HVAC Sealant, 5 gal, Pail, Black, Liquid

IAQ 8500 sealant is a high performance coating for use in duct work. This high-build coating is designed to bridge and reinforce duct liner or duct board insulation materials. IAQ 8500 can also be used to seal unlined duct work prior to component removal, preventing fiberglass and inanimate particulate from becoming airborne. IAQ 8500 dries to form a durable, flexible, moisture-resistant protective coating with a semi-gloss finish that minimizes dirt buildup on the coating surface. The high viscosity provides maximum bridging ability on insulation materials and reduces sagging and dripping when applied to the vertical and top surfaces of unlined duct. Successfully tested to ASTM standard C-411 “Hot surface performance of a coating on glass fiber blanket insulation”. ASTM E-84 Class A fire rating. Meets requirements of NFPA 90A/90B standard. Additionally, IAQ 8500 was tested in accordance with the procedures outlined in ASTM G 21 and recieved a No. 0 rating (No fungal growth, 0% growth on the specimens).

• High viscosity for maximum bridging ability
• Reduces sagging and dripping
