Filed:

Aug 5, 1983

Appl. No.:

6/520843

Inventors:

Charles A. Pagen - Hurst TX
George Stepien - Montclair NJ
Paul A. Morris - Bedford TX

Assignee:

Genstar Building Materials Company - Irving TX

International Classification:

B32B 900

US Classification:

428141

Abstract:

An improved inorganic fiber based roofing shingle for use in both high and low temperature environments is prepared by pre-coating an inorganic fibrous substrate with a polymer/bitumen composition prior to the application of a conventional asphalt or bitumen top coat, wherein the polymer content of the bitumen/polymer pre-coat composition ranges from about 3 to 99% by weight.

US Classification:

Abstract:

An all-weather inorganic fiber mat based roofing shingle is prepared using a novel bituminous coating formulation comprising a partially air blown asphalt combined with a styrenic elastomer and mineral stabilizer, which formulation more particularly comprises about 3 to 80% elastomeric polymer composition, 10 to 87% bituminous composition and 10 to 87% mineral stabilizer. In another embodiment, improved low and high temperature pliability and strength properties are also attained by blending recycled rubber or reclaimed rubber into the basic formulation which thereby comprises about 1 to 74% elastomeric polymer composition, 10 to 83% bituminous composition, 15 to 88% mineral stabilizer and about 1 to 74% recycled or reclaimed rubber.
