Abstract: The inventors of the present disclosure recognized that, surprisingly, the antimicrobial treatments used on cellulosic sponges do not work in hydrophilic polyurethane sponges. As such, the inventors of the present disclosure discovered a need for an antimicrobial treatment for use on hydrophilic polyurethane foam sponges. The present inventors invented one antimicrobial composition for use on hydrophilic polyurethane foam sponges including an acetate salt solution humectant. The present inventors invented another antimicrobial composition for use on hydrophilic polyurethane foam sponges including a non-halogen humectant comprising a salt solution having a pH between about 3 and 10 and a water activity of less than 0.9 at 25° C.

Abstract: The composition includes an acrylic polymer, a water-repellent polymer, and a stabilizer against ultraviolet light, in which the stabilizer is an ultraviolet light-absorber, a hindered amine light stabilizer, or a combination thereof. A coated article includes at least one of hardwood, softwood, oriented strand board, or plywood with a surface that is at least partially coated, wherein the surface that is at least partially coated has a b* value on the International Commission on Illumination L*, a*, and b* scale greater than 15 after 90 days of weathering. Methods of making the composition and the coated article are also described.
