AQUEOUS FLOOR FINISH COMPRISING THREE ACRYLATE POLYMERS

摘要

Acrylic resin floor finishes containing as the principal resin a zinc crosslinked acrylic polymer having a Knoop Hardness Number (KHN) from 13 to 19 are modified by incorporating minor proportions of a harder acrylic polymer, such as a methyl methacrylate polymer of a KHN hardness from 19 to 25, and a softer acrylic polymer, such as a copolymer of ethyl acrylate and methyl methacrylate of a KHN hardness below 5. Under adverse conditions of use, such as low temperature and low humidity, the finish has improved resistance to powdering.
