Abstract

The invention is a composition comprising: a) one or more film forming resins having at least one functional group capable of polymerization; b) one or more reactive diluents capable of reacting with the film forming resin; c) one or more silicon, titanium, zirconium, aluminum or metal containing compounds capable of promoting adhesion of the composition to glass; d) one or more fillers capable of imparting abrasion resistance to the composition when cured; and e) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety. The composition of the invention is useful as a frit on the window of a vehicle. Furthermore, the invention relates to a method for applying the coatings to glass and a method for bonding the coated glass to a structure or substrate, for instance, a building.

Claims

1. A composition comprising

a) one or more film forming resins having at least one functional group capable of polymerization;

b) one or more reactive diluents capable of reacting with the film forming resin;

c) one or more compounds capable of promoting adhesion of the composition to glass comprising Michael addition products of a siloxane further containing one or more hydrogen containing functional moieties which are secondary amines with a compound having two or more acrylate groups wherein the addition products have four or greater siloxy groups, at least one acrylate group and tertiary amines;

d) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety; and

e) one or more metals or metal compounds which render the composition reflective once cured.

2. A composition according to claim 1 wherein the metal compound is a metal oxide.

3. A composition according to claim 2 wherein the metal or metal oxide is, or based on, a transition group III, IV or V metal.

4. A composition according to claim 3 wherein the metal or metal oxide is gallium, copper, chromium, nickel, tin, iron, cobalt, silver and gold, or the oxides thereof, or various mixtures of such metals and oxides.

5. A composition according to claim 4 wherein the metal is gallium.

6. A composition according to claim 4 wherein the functional groups capable of polymerization of the film-forming resin polymerize when exposed to irradiation and the composition further comprises f) one or more catalysts or initiators capable of initiating polymerization of the film-forming resin.

7. A composition according to claim 4 wherein the one or more film-forming resins contain unsaturated moieties which polymerize when exposed to ultraviolet light and the initiator is a photoinitiator.

8. A compositions according to claim 7 wherein the one or more film forming resins contain unsaturated moieties which polymerize when exposed to electron beams.

9. A composition according to claim 4 which further comprises one or more surfactants, dispersants, inhibitors, or mixtures thereof.

10. A composition according to claim 4 which further comprises one or more fillers capable of imparting abrasion resistance to the composition when polymerized wherein the one or more fillers are dispersed in a dispersant.

11. A composition according to claim 8 wherein the film forming resins, and reactive diluents have acrylate functional moieties.

12. A composition according to claim 4 wherein the one or more compounds capable of promoting adhesion of the composition to glass comprises mixture of a Michael addition adduct and a high molecular weight adduct having multiple alkoxysilanes.

13. A composition according to claim 1 wherein the addition product contains 6 or greater siloxy groups.

14. A composition according to claim 13 wherein the addition product does not contain an active hydrogen atom.

15. A composition comprising

a) one or more film forming resins having at least one functional group capable of polymerization;

b) one or more reactive diluents capable of reacting with the film forming resin;

c) one or more compounds capable of promoting adhesion of the composition to glass comprising Michael addition products of a siloxane further containing one or more hydrogen containing functional moieties which are secondary amines with a compound having two or more acrylate groups wherein the addition products have four or greater alkoxy groups, at least one acrylate group and tertiary amines;

d) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety; and

e) one or more metals or metal compounds which render the composition reflective once cured.

16. A composition according to claim 15 wherein the addition product contains 6 or greater alkoxy groups.

17. A composition according to claim 16 wherein the addition product does not contain an active hydrogen atom.
