Energy Star Dirtguard IR Gloss

Energy Star Dirtguard IR Gloss is a highly modified 100% acrylic gloss coating that is low in V.O.C, and incorporates Astec Dirtguard and proprietary cross-linking technology.


A Water-Based, Infrared Heat Reflective, 100% Acrylic
Gloss Coating For Primed Metal & Asbestos Roofing.


As a result of ongoing research and development into dirt pick-up resistance for exterior coatings, Astec developed a new technology now registered to Astec as Dirtguard. As a result, the products remain clean far longer than conventional coatings, a necessary requirement for maximum retention of their Solar Reflectivity.

Coatings based on Astec Dirtguard technology incorporate the latest in surface curing and nano particle technology. The surface of the film cross links around nano particles to provide an extremely tight surface pack ensuring dirt will not become lodged within the cured film.

The product was originally designed to tolerate the demanding environments in Asian cities and provides excellent long-term resistance to dirt pick-up and mould.
