IAQ 8000 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 8000 can also be used to seal unlined duct work prior to component removal, preventing fibreglass and inanimate particulate from becoming airborne. IAQ 8000 dries to form a durable, flexible, moisture-resistant protective coating with a semi-gloss finish that minimises dirt build-up 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.
