Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
32 words
One-part moisture-curable polyurethane composition, characterized by triisocyanate prepolymer, an amount of an epoxy silane compound effective to crosslink said prepolymer and sufficient compatible liquid vehicle to make the composition suitable for application.
Claim 2
Dependent Claim
32 words
One-part moisture-curable polyurethane composition, characterized by triisocyanate prepolymer, an amount of an epoxy silane compound effective to crosslink said prepolymer and sufficient compatible liquid vehicle to make the composition suitable for application.
Claim 3
Dependent Claim
29 words
The composition of claim 1 further characterized by said triisocyanate prepolymer being selected from the group consisting of a reaction product of a diisocyanate and a triol and 1,3,5-triazine.
Claim 4
Dependent Claim
20 words
The composition of claim 2 further characterized by also including sufficient diisocyanate prepolymer to improve flexibility of the cured composition.
Claim 5
Dependent Claim
21 words
The composition of claim 1 further characterized by said diisocyanate being selected from the group consisting of aromatic and aliphatic diisocyanates.
Claim 6
Dependent Claim
25 words
The composition of claim 1 further characterized by said epoxy silane being selected from the group consisting of gamma glycidoxypropyltrimethoxy silane and beta-(3,4-epoxy- cyclohexyl)ethyltrimethylxy silane.
Claim 7
Dependent Claim
18 words
The composition of claim 1 further characterized by said composition also including sufficient flattening agent to reduce gloss.
Claim 8
Dependent Claim
27 words
An article characterized by being a substrate treated with a cured moisture-curable composition comprising triisocyanate prepolymer and an amount of epoxy silane sufficient to crosslink said prepolymer.
Claim 9
Dependent Claim
27 words
An article characterized by being a substrate treated with a cured moisture-curable composition comprising triisocyanate prepolymer and an amount of epoxy silane sufficient to crosslink said prepolymer.
Claim 10
Dependent Claim
12 words
The article of claim 7 further characterized by said substrate being wood.
Claim 11
Dependent Claim
29 words
An article according to either of claims 7 and 8 wherein the composition is the cured composition derived from the composition of any one of claims 1 to 6.
Claim 12
Independent Claim
74 words
A method of treating a substrate surface to provide it with a protective surface, said method comprising: (a) preparing the surface of said substrate for treatment, if needed; (b) applying to said surface a one-part moisture-curable polyurethane composition; and (c) subjecting the coating applied in (b) to conditions which facilitate the cure of said composition characterized by said one-part curable polymethane composition being a composition according to any one of claims 1 to 6.
Claim 13
Dependent Claim
13 words
A method according to claim 10 further characterized by said substrate being wood.
Claim 14
Dependent Claim
21 words
The method according to claim 10 further characterized by said substrate being selected from the group consisting of ceramic or cement.
