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:
(a) providing a substrate comprising a blend of low molecular weight and high molecular weight polyethylene resins;
(b) applying a primer to the substrate to provide a primed substrate;
(c) applying a base coat to the primed substrate, wherein the base coat comprises a first fluropolymer component and a plurality of particulate solids; and
(d) applying a top coat to the base coat, wherein the top coat comprises a clear acrylic coating and a second fluropolymer component.
2. The method of claim 1 , wherein the base coat further comprises a clear acrylic coating.
3. The method of claim 1 , wherein the first fluoropolymer component is fluorinated ethylene vinyl ether.
4. The method of claim 1 , wherein the fluoropolymer component is fluorinated ethylene vinyl ether.
5. A method for manufacturing a shingle suitable for roofing application, the method comprising: (a) providing a substrate comprising a blend of low molecular weight and high molecular weight polyethylene resins; (b) applying a primer to the substrate to provide a primed substrate; (c) applying a base coat to the primed substrate, wherein the base coat comprises a first fluoropolymer component; and (d) applying a top coat to the base coat, wherein the top coat comprises a clear acrylic coating and a second fluoropolymer component.
6. A shingle useable for roofing applications, wherein the shingle is produced by a process comprising: (a) providing a substrate comprising a blend of low molecular weight and high molecular weight polyethylene resins; (b) applying a primer to the substrate to provide a primed substrate; (c) applying a base coat to the primed substrate, wherein the base coat comprises a first fluoropolymer component; and (d) applying a top coat to the base coat, wherein the top coat comprises a clear acrylic coating and a second fluoropolymer component.
