Product Information

Fiberlock IAQ 7500 is a quick-drying, water-based adhesive coating/encapsulant for use on duct liner insulation surfaces.


It dries to form a durable, flexible, moisture-resistant protective coating on the duct liner insulation material.


Fiberlock IAQ 7500's semi-gloss finish minimizes dirt buildup on the coating surface which provides nutrients that feed mold colonies. It also contains an EPA-registered fungicide to resist mold growth on the cured film surface.


IAQ 7500 can be used in residential, commercial, or industrial facilities requiring maximum moisture and mold resistance. It is acceptable for use over faced or unfaced fiberglass duct liner insulation, and unfaced fiberglass duct board insulation.


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.



Apply Fiberlock IAQ 7000 to all surfaces of duct liner insulation by brush or airless spray. Application rate will vary depending on porosity of the insulation. Apply one coat by airless spray or two coats by brush.


Porous surfaces may require additional coats. Ensure that surfaces are completely sealed. Circulate fresh air through the HVAC system to help dry the coating. Exhaust air outside the building.
