Abstract
Novel, non-aqueous dispersions and coatings made therefrom particularly suited for use as automotive primers, sealers, topcoats and as industrial coatings.
Claims26
In a substrate coated with a multilayer decorative and/or protective coating which comprises:
- a) a basecoat comprising a pigmented film-forming resin;
- and
- b) a clearcoat comprising a film-forming resin applied to the surface of the basecoat composition;
- the improvement comprising utilizing as the basecoat composition a one-component, non-aqueous dispersion comprising a dispersion of a polymer in a non-polar hydrocarbon medium, wherein the polymer is produced by a free-radical addition polymerization reaction which takes place in the presence of an alkyd resin and wherein the polymer comprises at least one polar monomer and at least one amine-functional monomer.

- a) a basecoat comprising a pigmented film-forming resin;
- and
- b) a clearcoat comprising a film-forming resin applied to the surface of the basecoat composition;
- the improvement comprising utilizing as the basecoat composition a two-component, non-aqueous dispersion comprising:
- i) a first component comprising an isocyanate-functional material, and
- ii) a second component comprising a non-aqueous dispersion comprising a dispersion of a polymer in a non-polar hydrocarbon medium, wherein the polymer is produced by a free-radical addition polymerization reaction which takes place in the presence of an alkyd resin and wherein the polymer comprises at least one polar monomer and at least one amine-functional monomer;
- wherein upon combining the first component with the second component results in the reaction of the isocyanate-functional material with the non-aqueous dispersion.
