Fiberlock IAQ 7500 is a quick drying water-based adhesive coating/encapsulant for use on duct liner insulation surfaces. Fiberlock IAQ 7500 dries to form a durable, flexible, moisture-resistant protective coating on the duct liner insulation material. Its semi-gloss finish minimizes dirt buildup on the coating surface which provides nutrients that feed mold colonies.

Fiberlock IAQ 7500 also contains an EPA registered fungicide to resist mold growth on the cured film surface. Fiberlock IAQ 7500 can be used in residential, commercial, or industrial facilities requiring maximum moisture and mold resistance. Fiberlock IAQ 7500 is acceptable for use over faced or unfaced fiberglass duct liner insulation, and unfaced fiberglass duct board insulation. IAQ 7500 yields a clear finish, and is also available in white (IAQ 7000)
