Abstract
A laminar structure is disclosed that comprises a tacky mastic at least partially in contact with a ultra-violet (UV) light and moisture barrier. The structure can be employed for protecting a wide range of substrates such as wood, metal, concrete, cement, among other substrates. The structure can be cut or shaped into a virtually unlimited array of configurations. A release layer can be applied onto at least a portion of one or more sides of the structure. The release layer can be removed from the structure prior to applying the structure onto the substrate to be protected. Once applied the structure can protect the substrate from moisture, UV, microbial and animal attack.
Claims11
A laminated article comprising at least one mastic layer, at least on ultra-violet light resistant film or layer at least partially in contact with and adhered to one side of said at least one mastic layer and a second film or layer at least partially in contact with a second side of said at least one mastic layer wherein said at least one mastic layer comprises a combination comprising about 5 to about 30 weight percent of at least one member selected from the group consisting of butyl rubber, butyl styrene and polyisobutylene rubber and about 15 to about 35 weight percent of at least one member selected from the group consisting of polybutene and polyalphaolefin and about 40 to about 80 weight percent of at least one filler selected from the group consisting of aluminum stearate, calcium carbonate, clay, carbon ash, silicon dioxide, and titanium dioxide and about 1 to about 15 weight percent of at least one aliphatic hydrocarbon resin, and said at least one ultra-violet light resistant film or layer comprises a low density polyethylene having a dielectric strength of greater than 235 V/Mil when measured in accordance with ASTM D-149 and does not flow when measured in accordance with ASTM D217-88.
An article comprising at least one mastic layer, at least one ultra-violet light resistant film or layer at least partially in contact with and adhered to a first side of said at least one mastic layer and a second film or layer at least partially in contact with a second side of at least one mastic layer wherein said at least one mastic layer comprises a combination comprising polyisobutylene rubber, polybutene, butyl-styrene rubber, at least one filler selected from the group consisting of calcium carbonate, clay and silicon dioxide, and at least one aliphatic hydrocarbon resin, and wherein said at least one ultra-violet light resistant film or layer comprises a low density polyethylene having a dielectric strength greater than 235 V/mil in accordance with ASTM D-149.
