Tin-acrylate-containing polymers as algicidal agents in building materials

Granular materials having a tin-acrylate polymer coating are described which are algae-resistant. A method of inhibiting the growth of algae on roofing granules and other particulate materials attached to substrates by the use of tin-acrylate-containing polymers either as a topical treatment or as a...

Beschreibung
Zusammenfassung:	Granular materials having a tin-acrylate polymer coating are described which are algae-resistant. A method of inhibiting the growth of algae on roofing granules and other particulate materials attached to substrates by the use of tin-acrylate-containing polymers either as a topical treatment or as a polymeric binder is also presented. The methods presented are an advancement in the art in that in addition to algae-resistance, the polymers also confer other desirable properties to the granules onto which they are coated, such as increased adhesion to asphalt shingles.
