US Patent:

45297657, Jul 16, 1985

Filed:

Apr 9, 1984

Appl. No.:

6/598477

Inventors:

Herman C. DenHartog - Pontiac MI
Aloysius N. Walus - Troy MI

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

C08K 509
C08K 510
C08K 506
C09D 380

US Classification:

524294

Abstract:

A coating composition which cures at ambient temperatures of 20-80% by weight of a binder and 80-20% by weight of a solvent for the binder, the binder contains: A. an acrylic amino ester polymer of polymerized monomers of methyl methacrylate and monomers from the group of alkyl methacrylate and alkyl acrylate each having 2-12 carbon atoms in the alkyl group and the polymer has pendent amino ester or hydroxy amino ester groups wherein the amine group is a primary; and B. an acrylic polymer that has pendent polymerizable ethylenically unsaturated groups; the polymers having a weight average molecular weight of 6,000-80,000 determined by gel permeation chromotography; the composition is a two-component composition in which the acrylic amino ester polymer is blended with the acrylic polymer having pendent polymerizable groups before application; on application the amino groups of the acrylic amino ester polymer react with the polymerizable groups of the acrylic polymer and form a crosslinked finish; the composition is useful as an exterior finish for automobiles and trucks and for repairing finishes of automobiles and trucks.

US Classification:

524517

Abstract:

A coating composition which cures at ambient temperatures of 20-80% by weight of a binder and 80-20% by weight of a solvent for the binder, the binder contains about: A. 60-80% by weight, based on the weight of the binder, of an acrylic polymer of polymerized monomers of methyl methacrylate and an alkyl methacrylate, an alkyl acrylate or mixtures thereof, each having 2-12 carbon atoms in the alkyl group and the polymer has pendent amino ester or hydroxy amino ester groups; B. 20-40% by weight, based on the weight of the binder, of a glycidyl acrylic crosslinking polymer of polymerized monomers of glycidyl methacrylate or glycidyl acrylate and an alkyl methacrylate, alkyl acrylate or mixtures thereof, each having 2-12 carbon atoms in the alkyl group. The composition is useful as an exterior finish for automobiles and trucks and for repairing finishes of automobiles and trucks.
