IAQ 7500 Clear HVAC Sealant - PL
Increase airflow while minimizing dust buildup in HVAC systems with IAQ 7500 HVAC sealant. The clear product provide durable, flexible and moisture resistant penetrating coatings for duct insulation in residential, commercial or industrial facilities. IAQ 7500 resists mold growth* on the coating surface and can be used as a post-cleaning lock-down of inanimate residual particulates, such as fiberglass, dust and dirt.
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 and meets requirements of NFPA 90A/90B standard.
*Resistant to mold growth on the dry coating surface only
- Meets NFPA 90A/90B
- Penetrating coating for lined ductwork
- Lockdown for inanimate particulate contamination
Carefully clean up with a wet mop or HEPA vacuum. Clean and remove all dust and loose particulate from duct-work, being careful not to damage insulation. Follow duct manufacturer’s instructions for proper cleaning.
Apply IAQ 7500 with brush, roller or airless spray equipment.
- Brush: Synthetic, nylon or polyester bristle
- Roller: Synthetic Fiber 3/8” nap or longer
- Spray Settings: Pressure: 2200-3000 P.S.I. Tips: .017 to .023 tips
Prior to application, mix thoroughly to achieve a uniform consistency. Apply IAQ 7500 to all surfaces 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. IAQ 7500 can be applied using HVAC robotic spray applicators (contact Fiberlock for more information).
- Smooth Surfaces: 100-200 sq. ft./gal.
- Porous Surfaces: Depends on porosity
- @ 70°F 50% R.H
- To Touch – 1 hour
- To Recoat – 8-16 hours
Clean tools and drippings with warm soapy water before IAQ 7500 dries. Dispose of all waste according to all existing local, state and federal regulations.
Store in a dry place at temperatures between 40°F (4.5°C) and 90°F. (32°C). Stir thoroughly. Do not mix with any other coatings, solvents or colors in oil. The IAQ 7500 coating is resistant to mold only on the surface of the coating. No mold resistance claim is made other than to the coating itself. The use of this product does not protect users or others against food-borne or disease-causing bacteria, viruses, germs or other disease-causing organisms. Do not apply when air or surface temperature is below 50°F, or when drying conditions are poor or when surfaces are above a 15% moisture level content. Use adequate ventilation during application. When applying with a sprayer, wear a NIOSH approved respirator with any R, P, N or HE filter. For interior use only. Check with local building code enforcement authority for any additional requirements.
