Non-asphaltic coatings, non-asphaltic roofing materials, and methods of making the same
Non-asphaltic coatings for roofing materials, roofing materials made therefrom and methods of preparing such coatings and roofing materials utilize a combination of a crude tall oil-based continuous phase material, a resinous hardening agent, and a polymer.
1. A non-asphaltic roofing shingle comprising a substrate having a coating which comprises a crude tall oil-based continuous phase material, a resinous hardening agent, a polymer, and a filler,
wherein the softening point of the coating ranges from 175-320° F., and
wherein the penetration of the coating ranges from 5-100 dmm measured at 77° F.
2. The non-asphaltic roofing shingle according to claim 1 , wherein the substrate comprises a fiberglass mat, a polyester mat, a scrim, a coated scrim, or a combination thereof.
3. The non-asphaltic roofing shingle according to claim 1 , wherein the non-asphaltic roofing shingle is a single layer shingle or a laminated shingle having two or more layers.
4. The non-asphaltic roofing shingle according to claim 1 , wherein a thickness of the coating on the substrate ranges from 5-100 mils.
5. The non-asphaltic roofing shingle according to claim 1 , wherein the non-asphaltic roofing shingle comprises one or more layers of the coating.
6. The non-asphaltic roofing shingle according to claim 1 , wherein the non-asphaltic roofing shingle further comprises granules.
