IAQ 8500 is trusted for use in duct work, to bridge and reinforce duct liner or duct board insulation materials, and to seal unlined duct work prior to component removal, preventing fiberglass and inanimate particulate from becoming airborne. IAQ 8500 forms a durable, flexible, moisture-resistant protective coating with a semi-gloss finish that minimizes dust 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 rated, meets requirements of NFPA 90A/90B standard.
Features:
- High viscosity for maximum bridging ability
- Reduces sagging and dripping
- Meets NFPA 90A/90B
- Resurfaces and encapsulates fiberglass lined duct work
- Resists mold growth*
*Resists mold growth on the dry coating surface only
