  • Patent number: 6337029
    Abstract: A composition comprising bifluoride salts in a somewhat viscous form for roughening glass, ceramic and porcelain surfaces in preparation for refinishing includes: a. bifluoride salts in an amount ranging from 10.0 to 85.0 parts by weight; b. thickener in an amount ranging from 0.1 to 5.0 parts by weight; c. organic solvent in an amount ranging from 2.0 to 20.0 parts by weight; and d. water in an amount ranging from 7.0 to 75.0 parts by weight. A coating of the composition is applied to a substrate, such as those having low surface tensions and to which paint adhesion is difficult. The coating is left in contact with the substrate for a period of time effective to roughen the substrate. The coating is then removed and discarded or alternatively, collected and reused. The substrate after treatment will have a roughened surface from which improved paint adhesion results.

  • Patent number: 6187374
    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.
