Shingle product
A shingle release film product and a roofing shingle product containing such film are described. The shingle release film product comprises a polymer film, a bonding material coating, and a release coating. The release coating comprises a silicone. The bonding material coating comprises an olefin polymer. The film product may be present on a roofing shingle product. The bonding material coating of the film product present on a shingle product is configured to adhere to an adjacent shingle.
1. A roofing shingle product comprising:
a shingle having a first side and a second side;
a shingle adhesive located on the first side of the shingle; and
a polymer film product having a first side and a second side, a release coating applied to the first side of the polymer film product and a bonding material coating applied to the second side of the polymer film product, the first side of the polymer film product covering the shingle adhesive such that the release coating contacts the shingle adhesive, the bonding material coating comprising an olefin polymer and being configured to adhere to an adjacent shingle.
2. A roofing shingle product as defined in claim 1 , wherein the shingle comprises at least one petroleum based polymer.
3. A roofing shingle product as defined in claim 2 , wherein the shingle comprises styrene-butadiene (SBR), acrylonitrile-butadiene (NBR), chloroprene rubber (CR), butadiene rubber (BR), isoprene rubber (IR), butyl rubber (IIR), ethylene-propylene rubber (EPR), ethylene-propylene diene monomer (EPDM), polyisobutylene (PIB), chlorinated polyethylene (CPE), natural rubber or mixtures thereof.
4. A roofing shingle product as defined in claim 1 , wherein the shingle further comprises a reinforcing fiber.
5. A roofing shingle product as defined in claim 4 , wherein the reinforcing fiber comprises glass fibers.
6. A roofing shingle product as defined in claim 1 , wherein the olefin polymer contained in the bonding material coating comprises an acid modified polyolefin, the bonding material coating further containing a cross-linking agent.
7. A roofing shingle product as defined in claim 6 , wherein the acid modified polyolefin comprises a carboxylic acid or a carboxylic acid anhydride modified polyethylene, polypropylene, or polybutylene polymer.
8. A roofing shingle product as defined in claim 7 , wherein the carboxylic acid or carboxylic acid anhydride modified polyethylene, polypropylene, or polybutylene is formed from a dicarboxylic acid or a dicarboxylic acid anhydride.
9. A roofing shingle product as defined in claim 7 , wherein the carboxylic acid or carboxylic acid anhydride modified polyethylene, polypropylene, or polybutylene comprises a carboxylic acid anhydride.
10. A roofing shingle product as defined in claim 9 , wherein the carboxylic acid anhydride comprises an anhydride of maleic acid.
11. A roofing shingle product as defined in claim 6 , wherein the cross-linking agent contained in the coating comprises an oxazoline polymer.
12. A roofing shingle product as defined in claim 6 , wherein the cross-linking agent comprises an oxazoline modified acrylic polymer.
13. A roofing shingle product as defined in claim 1 , wherein the shingle adhesive comprises a rubber combined with an asphalt.
14. A roofing shingle product as defined in claim 1 , wherein the release coating on the polymer film product comprises a silicone.
15. A roofing shingle product as defined in claim 1 , wherein the polymer film product comprises a polyester film.
16. A roofing shingle product as defined in claim 15 , wherein the polymer film comprises a biaxially stretched polyester film that has a thickness of from about 0.1 mils to about 15 mils.
17. A roofing shingle product as defined in claim 1 , wherein the bonding material coating has a thickness of from about 1 nm to about 100 nm.
18. A roofing shingle product as defined in claim 1 , wherein the roofing shingle product includes a stack of at least two shingles wherein the second side of the polymer film product contacts the second side of an adjacent shingle.
19. A film product for covering a shingle adhesive on a shingle comprising:
a polymer film product having a first side and a second side, a release coating applied to the first side of the polymer film product, the release coating containing a silicone, the polymer film product further including a bonding material coating applied to the second side of the polymer film product, the bonding material coating comprising an acid modified polyolefin and a cross-linking agent.
