Abstract
Abstract What are disclosed are a one pot moisture-curable two-component coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein and a second component having at least one oxazolidine group therein, methods of forming a tenacious coating therewith on non-porous substrates such as glass and of further applying a resinous sealant composition over such a tenacious coating used as a primer, and coated substrates having such a tenacious coating thereon without or with a further resinous sealant composition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
66 words
A method for forming a tenacious coating, resistant to weathering, on a non-porous substrate, which method comprises applying to said non-porous substrate a "one pot" moisture-curable coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein, and a second component having at least one oxazolidine group therein, and curing said composition in the presence of moisture.
Claim 2
Independent Claim
66 words
A method for forming a tenacious coating, resistant to weathering, on a non-porous substrate, which method comprises applying to said non-porous substrate a "one pot" moisture-curable coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein, and a second component having at least one oxazolidine group therein, and curing said composition in the presence of moisture.
Claim 3
Dependent Claim
12 words
A method as in claim 1 wherein said nonporous substrate is glass.
Claim 4
Dependent Claim
14 words
A tenacious coating on a glass substrate made by the method of claim 2.
Claim 5
Dependent Claim
28 words
A method as in claim 1 wherein a resinous sealant composition is further applied over said tenacious coating, which latter serves as a primer for said sealant composition.
Claim 6
Dependent Claim
16 words
A method as in claim 4 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 7
Dependent Claim
16 words
A method as in claim 4 wherein said tenacious coating is on a non-porous glass substrate.
Claim 8
Dependent Claim
16 words
A coated non-porous substrate having a tenacious coating thereon, made by the method of claim 1.
Claim 9
Dependent Claim
27 words
A coated non-porous substrate having a tenacious primer coating thereon and a resinous sealant composition bonded to said primer coating, made by the method of claim 4.
Claim 10
Dependent Claim
13 words
A coated non-porous substrate as in claim 8 wherein said substrate is glass.
Claim 11
Dependent Claim
11 words
A coated non-porous substrate made by the method of claim 5.
Claim 12
Dependent Claim
12 words
A coated substrate as in claim 10 wherein said substrate is glass.
