US 11,230,645 B2 · Scuff resistant and chip resistant architectural compositions

Abstract

Solutions to the problems of scuffing and chipping of the paint films in high traffic areas and in tight spaces, such as dressing rooms in department stores, where multiple scrapings of the wall paints are created by consumers, clothes hangers, shoes, etc., and hallways and conference rooms in office and other commercial buildings are disclosed. Wax seeded latex polymers admixed with an added wax in architectural compositions and optionally with polyurethane resin are utilized to create paint films that are resistant to scuffing and chipping.

Claims32

Dependent claims

An architectural aqueous coating composition that forms a paint film, said paint film is capable of resisting scuffing or chipping, wherein the architectural aqueous coating composition comprises:

a wax seeded latex, wherein the wax seeded latex comprises a hydrophobic, wax compound entrapped within a polymeric matrix,
a wax, wherein the wax makes up from 1.04 wt. % to 4.77 wt. % of the architectural aqueous coating composition, and
a coalescent aid, wherein a range of wax seeded latex to coalescent aid weight ratios is from 14.7 to 16.15.

Dependencies are inferred from the claim text.
