    摘要: The invention is in a conductive prepolymer composition which when polymerized and cured is used to coat a substrate material such as steel, stainless steel, iron, brass, copper, aluminum, platinum, titanium, silver, gold, Telfon, plastics, glass, or combinations thereof. It comprises: (a) from 25 to 99 parts by weight of a poly(amide-imide) prepolymer; (b) from 1 to 25 parts by weight of a trifunctional ester selected from the group consisting of trifunctional methacrylate ester, trifunctional acrylate ester, and mixtures thereof; (c) from 0.5 to 15 parts by weight of an organo-reactive silane consisting of an amino group containing alkoxysilane having the formula NH2(CH2)nSi(OC2H5)3, where n is an integer from 1 to 20; and (d) a conductive additive. The invention also provides polymer coated substrates having a tenaciously bound polymer layer which is corrosion resistant, has advantageous properties of conductivity and can be soldered.

    摘要: A power flosser tip incorporating a tooth-whitening coating. The coating is typically abrasive, and whitens teeth by scraping or wearing down hardened plaque or other tooth discolorations. The coating may also whiten teeth through a chemical reaction. The coating may be flavored in order to enhance user enjoyment. The coating is chemically bonded to the flosser tip, and dissolves when in contact with saliva or water at room temperature and pressure.
