Synthetic roofing shingles
Disclosed is a coated synthetic shingle that exhibits increased resistance to ultra-violet radiation. The shingle is useable for roofing applications and includes a substrate having a substrate surface and a base coat that is applied to the substrate surface. The base coat preferably includes a first fluoropolymer component. The shingle can also include a top coat that is applied to the base coat. The top coat preferably includes a clear acrylic coating. A method for manufacturing the shingle is also disclosed.
1. A method for manufacturing a coated synthetic shingle, the method comprising:
applying a primer to the substrate to provide a primed substrate;
spraying a base coat onto the primed substrate, wherein the base coat includes a colored acrylic coating and a first fluoropolymer component; and
applying a top coat to the base coat, wherein the top coat includes a clear acrylic coating and a second fluoropolymer component.
2. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface, wherein the substrate is constructed from a blend of low molecular weight and high molecular weight polyethylene resins; and
a viscous base coat applied to the substrate surface, wherein the base coat includes a first fluoropolymer component.
3. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface, wherein the substrate includes a fire-retardant filler; and
a base coat applied to the substrate surface, wherein the base coat includes a first fluoropolymer component.
4. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface; and
a base coat applied to the substrate surface, wherein the base coat includes a first fluoropolymer component and particulate solids.
5. The shingle of claim 4 , wherein the particulate solids are micronized polypropylene having an average sphere size of 50–500 microns.
6. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface;
a base coat applied to the substrate surface, wherein the base coat includes a first fluoropolymer component; and
a top coat applied to the base coat, wherein the top coat includes a clear acrylic coating and particulate solids.
7. The shingle of claim 6 , wherein the particulate solids are micronized polypropylene having an average sphere size of 50–500 microns.
8. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface, wherein the substrate is fabricated from a blend of high and low molecular weight polyethylene;
a base coat applied to the substrate surface, wherein the base coat includes a colored acrylic coating; and
a top coat applied to the base coat, wherein the top coat includes a clear acrylic coating, a second fluoropolymer component and a plurality of particulate solids.
9. A shingle useable for roofing applications, the shingle comprising:
a substrate having a substrate surface;
a base coat applied to the substrate surface, wherein the base coat includes a colored acrylic coating; and
a top coat applied to the base coat, wherein the top coat includes a clear acrylic coating, a second fluoropolymer component and a plurality of particulate solids, wherein the plurality of particulate solids are micronized polypropylene having an average sphere size of about 300 microns.
