Sentinel’s 24-7 ZERO HVAC coatings are specialized coatings designed to be applied within HVAC systems, on HVAC insulation and primed or galvanized metal. Sentinel 24-7 ZERO HVAC coatings are thick, flexible and will bridge and reinforce duct liner and duct board insulation material. They will seal HVAC surfaces from odors caused by fire, smoke, mold and mildew. Like the rest of our ZERO family, 24-7 ZERO HVAC contain no Volatile Organic Compounds (VOCs), are free of Hazardous Air Pollutants (HAPs), and offer virtually no odor. Both White and Black 247- ZERO HVAC products contain an approved EPA registered fungistatic agent that serves to inhibit the growth of fungus such as mold and mildew on the surface of the coating. HVAC systems treated with 24-7 ZERO HVAC coatings will have increased air flow while minimizing dirt build up.

Product Application Limitations
24-7 ZERO HVAC should be applied at temperatures above 50°F and with a relative humidity level that is below protection, it is vitally important that all surfaces be completely coated with 24-7 ZERO HVAC. For airless applications, use a .021 – .025 tip, a minimum 2500 P.S.I. and maintain a fan size of approximately 12 inches. When using a roller use a 3/8” nap roller and when brushing, use strokes 90° to each other.
