Laminar structure
View Patent ↗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.
1. A die cut structure for protecting wooden articles comprising at least one tacky mastic layer, and at least a portion of the mastic layer adhered to at least one UV and moisture resistant barrier film or layer wherein the barrier fun or layer is electrically non-conductive and the mastic layer is adhered to the wooden article.
2. The die cut structure of claim 1 wherein the mastic layer comprises at least one elastomer, the barrier film or layer comprises polyethylene and further comprising at least one removable release film or layer in contact with the mastic layer.
3. The structure of claim 1 wherein the mastic layer comprises butyl rubber, polybutene and at least one filler.
4. The structure of claim 3 wherein filler comprises at least one member from the group consisting of calcium carbonate, clay, aluminum stearate, silicon dioxide and titanium dioxide.
5. The structure of claim 1 wherein UV barrier film or layer comprises opaque low density polyethylene.
6. The structure of claim 2 wherein said release layer comprises high density polyethylene.
7. The structure of claim 1 wherein said structure has a dielectric strength of greater than 235 V/Mil.
8. The structure of claim 1 wherein said structure has a tensile adhesive strength of at least 17 psi.
9. The structure of claim 1 wherein said mastic layer comprises about 75 to about 90 wt. % of at least one additive.
10. The structure of claim 9 wherein said additive comprises at least one member selected from the group consisting of butyl rubber, butyl-stryrene rubber and polyisobutylene rubber.
11. An extruded and die-cut article comprising at least one mastic layer, at least on UV 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 butyl rubber, butyl styrene, polybutene, aliphatic hydrocarbon resin and calcium carbonate and said at least one UV resistant film comprises low density polyethylene having a dielectric strength of greater than 235 V/Mil when measured in accordance with ASTM D-149.
12. The article of claim 11 wherein said article is adhered to a substrate comprising wire rope.
13. An article comprising at least one mastic layer and at least one moisture resistant film or layer at least partially in contact with and adhered to one side of said at least one mastic layer wherein said at least one mastic layer comprises a combination comprising butyl rubber, polybutene, butyl-styrene rubber and calcium carbonate, and said at least one moisture resistant film comprises low density polyethylene and said mastic layer contacts a substrate comprising at least one member selected from the group consisting of metal and wood.
14. The article of claim 11 wherein the second film or layer is removable.
