Abstract
A composition that can adhere to a substrate in an environment of hot water and soap includes: a. epoxy resin in an amount ranging from about 25.0 to about 60.0 parts by weight; b. acrylic resin in an amount ranging from about 5.00 to about 50.0 parts by weight; c. amine in an amount ranging from about 30.0 to about 45.0 parts by weight, wherein the amine is effective to crosslink the epoxy resin; and d. silane in an amount ranging from greater than 0 to about 10.0 parts by weight. Solvent may also be present in an amount ranging from 0 to 70.0% by weight based upon the total weight of the composition. The coating is applied to a substrate, such as those which have low surface tension and to which bonding is difficult. The substrate may be fastened to a construction material disposed in a sink, tub or shower area. The coating on at least a portion of the substrate is subjected to the environment of hot water and soap and adheres to the substrate despite exposure to the environment.
