Fiberlock IAQ 8500 is a dual-purpose, high performance coating designed for use in duct work. Fiberlock IAQ 8500 is designed to penetrate and reinforce duct liner or duct board insulation materials. Fiberlock IAQ 8500 can also be used to seal unlined duct work prior to component removal, preventing microbial particulate from becoming airborne.

Fiberlock IAQ 8500 is a non-flammable, water-based formulation that forms a flexible membrane in duct liner insulation materials. Fiberlock IAQ 8500 is high in viscosity to provide maximum binding ability on insulation materials. Fiberlock IAQ 8500 is manufactured from premium 100% acrylic resins to allow for optimal durability and flexibility, necessary for air duct environments. IAQ 8500 yields a black finish, and is also available in white (IAQ 8000).
