Abstract
Abstract A composition comprising a silane, siloxane or combination thereof, a catalyst and an ultraviolet radiation absorber. The composition is applied to the surfaces of carbon central structures to diminish the harmful effects thereon of water and ultraviolet radiation. Some examples of carbon central structures as defined herein are fences, decks, awnings, seat covers, umbrellas, carpeting and furniture. The composition is applied to the surface to be treated and allowed a sufficient time in order to penetrate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
231 words
A method for treating wood or paper comprising the step of applying a composition capable of reducing the effects of ultraviolet radiation and water to the wood or paper surface wherein the composition comprises: a silane or siloxane or combination thereof; and a catalyst; wherein the silane has the general formula: R.sub.m --Si--X.sub.4--m wherein m is 1 or 2; and X is a halogen, hydroxyl, R or R 1 ; R is an ultraviolet radiation absorber bonded directly to the silicon atom and is capable of reducing the effects of ultraviolet radiation on wood or paper selected from a grouping of unsaturated or aromatic compounds, and R 1 being an alkyl group containing from 1 to about 8 carbon atoms, a hydroxyalkyl group, or an alkoxyalkyl group; and wherein the siloxane is represented by the general structure or formula: ##STR2## wherein R 2 and R 3 are bonded directly to the silicon atom and are ultraviolet radiation absorbers capable of reducing the effects of ultraviolet radiation on wood or paper and are independently selected from a grouping of unsaturated or aromatic compounds, and Y is an integer between 1 and about 100; and wherein W is a halogen, hydroxyl, alkyl, aryl or alkoxy, wherein the composition is not an emulsion and is not cured by ultraviolet radiation, and further comprising: a catalytically effective amount of titanium acetylacetonate and dibutyl tin dilaurate.
Claim 2
Independent Claim
231 words
A method for treating wood or paper comprising the step of applying a composition capable of reducing the effects of ultraviolet radiation and water to the wood or paper surface wherein the composition comprises: a silane or siloxane or combination thereof; and a catalyst; wherein the silane has the general formula: R.sub.m --Si--X.sub.4--m wherein m is 1 or 2; and X is a halogen, hydroxyl, R or R 1 ; R is an ultraviolet radiation absorber bonded directly to the silicon atom and is capable of reducing the effects of ultraviolet radiation on wood or paper selected from a grouping of unsaturated or aromatic compounds, and R 1 being an alkyl group containing from 1 to about 8 carbon atoms, a hydroxyalkyl group, or an alkoxyalkyl group; and wherein the siloxane is represented by the general structure or formula: ##STR2## wherein R 2 and R 3 are bonded directly to the silicon atom and are ultraviolet radiation absorbers capable of reducing the effects of ultraviolet radiation on wood or paper and are independently selected from a grouping of unsaturated or aromatic compounds, and Y is an integer between 1 and about 100; and wherein W is a halogen, hydroxyl, alkyl, aryl or alkoxy, wherein the composition is not an emulsion and is not cured by ultraviolet radiation, and further comprising: a catalytically effective amount of titanium acetylacetonate and dibutyl tin dilaurate.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein the ultraviolet radiation absorber selected from the grouping of unsaturated compounds comprises derivatives of ethylenes, dienes, acetylenes, alone or linked to aromatic groupings.
