Abstract

Enhanced tear strength asphalt roofing composites, e.g., roofing shingles which can meet the current ASTM D-3462 standard for tear strength, include an adhesion modifier treated, preferably a polysiloxane treated, glass fiber mat.

Claims (7)

1. A glass fiber mat for use in making a roofing composite of asphalt-coated hand sheets and asphalt shingles, said mat comprising, by weight, about 68% to about 90% of fibers; about 10% to about 32% by weight of an organic resin binder; and having applied to the surface of said glass mat about 0.001% to about 20% by weight of an adhesion modifier which is non-reactive with said surface of the glass mat but which induces fiber pull-out during tear of the composite and thereby provides improved composite tear strength wherein said asphalt-coated hand sheets and asphalt shingles thereof meet or exceeds Tear Test D-1922 (ASTM D-3462, Jul. 10, 1997 Ed), and wherein said adhesion modifier is a polysiloxane.

2. A glass fiber mat according to claim 1 wherein the amount of adhesion modifier is about 0.01% to about 10%.

3. A glass fiber mat according to claim 1 wherein said polysiloxane is a polyalkyl siloxane, a polyaryl siloxane, a polyalkylaryl siloxane or a polyether siloxane, or derivative thereof.

4. A glass fiber mat according to claim 3 wherein said polysiloxane is a polydimethyl siloxane or derivative thereof.

5. A glass fiber mat according to claim 3 wherein said polysiloxane has a molecular weight>600.

6. A glass fiber mat according to claim 1 wherein said organic resin binder includes a urea-formaldehyde resin.

7. A glass fiber mat of claim 1 wherein said glass fibers have a length of about 3 mm to about 130 mm, and a diameter of about 5 micrometers to about 25 micrometers.
