Abstract
Abstract What are disclosed are a poly(meth)acrylate polymer having pendant hydrolyzable alkoxysilane groups thereon prepared by reacting a poly(meth)acrylate polymer having pendant hydroxy groups thereon with an isocyanato functional alkoxysilane having 1 to 3 hydrolyzable lower alkoxy groups present on the silicon atom thereof; a substrate such as glass or aluminum having a tenacious coating thereon of such a polymer alone or in admixture with another, different, resinous binder component; such a substrate further having a resinous sealant composition applied over said tenacious coating as a primer; and methods for making such a polymer and such coated substrates.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
71 words
A method for forming a tenacious coating, resistant to weathering, on a substrate, which method comprises applying to said substrate a resinous composition comprising a poly(meth)acrylate polymer having pendant hydrolyzable alkoxysilane groups grafted thereon, said poly(meth)acrylate polymer being a copolymer consisting essentially of one or more hydroxyalkyl acrylates or methacrylates and one or more alkyl acrylates or methacrylates, and then hydrolyzing said pendant hydrolyzable alkoxysilane groups in the presence of moisture.
Claim 2
Independent Claim
71 words
A method for forming a tenacious coating, resistant to weathering, on a substrate, which method comprises applying to said substrate a resinous composition comprising a poly(meth)acrylate polymer having pendant hydrolyzable alkoxysilane groups grafted thereon, said poly(meth)acrylate polymer being a copolymer consisting essentially of one or more hydroxyalkyl acrylates or methacrylates and one or more alkyl acrylates or methacrylates, and then hydrolyzing said pendant hydrolyzable alkoxysilane groups in the presence of moisture.
Claim 3
Dependent Claim
22 words
The method as in claim 1 wherein said resinous composition additionally comprises a film-forming resinous binder component different from said poly(meth)acrylate polymer.
Claim 4
Dependent Claim
11 words
A method as in claim 1 wherein said substrate is glass.
Claim 5
Dependent Claim
17 words
A substrate having thereon a tenacious coating, resistant to weathering, made by the method of claim 1.
Claim 6
Dependent Claim
17 words
A substrate having thereon a tenacious coating, resistant to weathering, made by the method of claim 2.
Claim 7
Dependent Claim
17 words
A substrate having thereon a tenacious coating, resistant to weathering, made by the method of claim 3.
Claim 8
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 9
Dependent Claim
28 words
A method as in claim 2 wherein a resinous sealant composition is further applied over said tenacious coating, which latter serves as a primer for said sealant composition.
Claim 10
Dependent Claim
28 words
A method as in claim 3 wherein a resinous sealant composition is further applied over said tenacious coating, which latter serves as a primer for said sealant composition.
Claim 11
Dependent Claim
16 words
A method as in claim 7 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 12
Dependent Claim
16 words
A method as in claim 8 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 13
Dependent Claim
16 words
A method as in claim 9 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 14
Dependent Claim
25 words
A substrate having a tenacious primer coating thereon and a resinous sealant composition bonded to said primer coating, made by the method of claim 7.
Claim 15
Dependent Claim
25 words
A substrate having a tenacious primer coating thereon and a resinous sealant composition bonded to said primer coating, made by the method of claim 8.
Claim 16
Dependent Claim
26 words
A glass substrate having a tenacious primer coating thereon and a resinous sealant composition bonded to said primer coating, made by the method of claim 9.
Claim 17
Dependent Claim
16 words
A substrate as in claim 13 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 18
Dependent Claim
16 words
A substrate as in claim 14 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
Claim 19
Dependent Claim
17 words
A glass substrate as in claim 15 wherein said resinous sealant composition is a moisture-curable polyurethane sealant.
