Abstract
This invention, in embodiments, relates to a roofing material comprising (a) a substrate having a top surface and a back surface, (b) a plurality of self-healing particles embedded into the substrate, and (c) a coating applied onto the substrate having the plurality of self-healing particles embedded therein, to provide a coated substrate. The plurality of self-healing particles can be embedded into the top surface and/or the back surface of the substrate. The roofing material can further include a plurality of roofing granules applied to a top surface of the coating of the coated substrate. This invention, in embodiments, further relates to a method of preparing such a roofing material.
Claims8
A roofing material comprising:
- (a) a substrate having a top surface and a back surface, the substrate being uncoated and comprising one of a fiberglass mat, a polyester mat, a scrim, or a combination thereof;
- (b) a plurality of self-healing particles embedded into the top surface of the uncoated substrate, such that the plurality of self-healing particles directly contact the top surface of the uncoated substrate, wherein each self-healing particle of the plurality of self-healing particles comprises an external shell and a film-forming material within the external shell, such that one or more self-healing particles of the plurality of self-healing particles is configured to rupture upon impact to the substrate, to thereby dispense the film-forming material to help repair any damage to the roofing material;
- and
- (c) a single coating applied onto the top surface of the substrate having the plurality of self-healing particles embedded therein, to provide a coated substrate, wherein the coating comprises one of an asphaltic coating, a non-asphaltic coating, a polymer-modified asphaltic coating, or a combination thereof,
- wherein the top surface of the substrate has an average surface coverage amount of the plurality of self-healing particles of between 70% and 100%.
