ABSTRACT:
A rigid, glass fiber airduct for conveying an airstream has an interior surface, adapted to be in contact with the airstream, which is coated with a polymeric coating comprising an organic or inorganic biocide. The polymeric coating has a dry solids content between 10 and 20 grams per square foot of duct board surface and retains its abrasion strength and puncture resistance whereby the interior surface of the airduct can be cleaned by conventional industrial or commercial cleaning procedures while in service without exposing glass fibers to the airstream.
