Abstract
Disclosed is a coating composition that generally includes a waterborne alkyd resin including urethane groups and a crosslinking acrylic latex resin. An alkyd resin and an acrylic latex resin can be included in a composition in relative amounts to yield a cured coating that has a higher pendulum hardness than that of a coating formed from an otherwise identical composition that excludes the acrylic latex resin. The composition can be formulated such that solids of said waterborne urethane alkyd resin and solids of said crosslinking acrylic latex resin are present in a mass ratio ranging from 20:80 to 80:20 with respect to one another A method of preparing a coating composition generally includes blending relative amounts of an alkyd resin and an acrylic latex resin.
