Method for Surface Coating for Improved Weatherability of Building Products
The present invention relates to a weatherable building product comprising a wood component. The wood component has at least a portion which is coated with a coating composition comprising a blend of saturated polymers, synthetic resins, plasticizers, and/or filler materials. The wood component comprises solid wood or fiber-based materials.
1 . A method for making a weatherable building product comprising:
coating at least a portion of a wood component with a surface coating composition comprising one or more saturated polymers, one or more synthetic resins, and one or more plasticizers.
2 . The method according to claim 1 wherein the surface coating composition further comprises one or more filler materials.
3 . The method of claim 1 wherein the one or more saturated polymers are homopolymers of propenes, butenes, isobutenes, styrenes, ethenes, isoprenes and propenes.
4 . The method of claim 1 wherein the one or more saturated polymers are heteropolymers of propenes, butenes, isobutenes, styrenes, ethenes, isoprenes and propenes.
5 . The method of claim 1 wherein the one or more saturated polymers range from about 0.01% to about 50% by weight of the surface coating composition.
6 . The method of claim 1 wherein the one or more synthetic resins are aliphatic resins, aromatic resins, polyester resins, epoxy resins and mixtures thereof.
7 . The method of claim 1 wherein the one or more synthetic resins range from about 0.01% to about 50% by weight of the surface coating composition.
8 . The method of claim 1 wherein the one or more plasticizers are stearic acids and naphthenic oils.
9 . The method of claim 1 wherein the one or more plasticizers range from about 0.01% to about 50% by weight of the surface coating composition.
10 . The method of claim 2 wherein the one or more filler materials are oxidic fillers, silicatic fillers, water-soluble metal salts, organosilane compounds, fumed silica and antioxidants.
11 . The method of claim 2 wherein the one or more filler materials range from about 0.01% to about 50% by weight of the surface coating composition.
12 . The method of claim 1 wherein the wood component comprises solid wood or fiber-based materials.
13 . The method of claim 12 wherein the wood component is made of fiber, wax and resin.
14 . The method of claim 13 wherein the wood component is an oriented strand board (OSB).
15 . A weatherable building product comprising:
a wood component;
at least a portion of the wood component being coated with a surface coating composition comprising one or more saturated polymers, one or more synthetic resins, and one or more plasticizers.
16 . The building product according to claim 15 wherein the surface coating composition further comprises one or more filler materials.
17 . The building product of claim 15 wherein the one or more saturated polymers are homopolymers of propenes, butenes, isobutenes, styrenes, ethenes, isoprenes and propenes.
18 . The building product of claim 15 wherein the one or more saturated polymers are heteropolymers of propenes, butenes, isobutenes, styrenes, ethenes, isoprenes and propenes.
19 . The building product of claim 15 wherein the one or more saturated polymers range from about 0.01% to about 50% by weight of the surface coating composition.
20 . The building product of claim 15 wherein the one or more synthetic resins are aliphatic resins, aromatic resins, polyester resins, epoxy resins and mixtures thereof.
21 . The building product of claim 15 wherein the one or more synthetic resins range from about 0.01% to about 50% by weight of the surface coating composition.
22 . The building product of claim 15 wherein the one or more plasticizers are stearic acids and naphthenic oils.
23 . The building product of claim 15 wherein the one or more plasticizers range from about 0.01% to about 50% by weight of the surface coating composition.
24 . The building product of claim 16 wherein the one or more filler materials are oxidic fillers, silicatic fillers, water-soluble metal salts, organosilane compounds, fumed silica and antioxidants.
25 . The building product of claim 16 wherein the one or more filler materials range from about 0.01% to about 50% by weight of the surface coating composition.
26 . The building product of claim 15 wherein the wood component comprises solid wood or fiber-based materials.
27 . The building product of claim 15 wherein the wood component is made of fiber, wax and resin.
28 . The building product of claim 27 wherein the wood component is an oriented strand board (OSB).
