  • Water base adhesion promotor for polypropylene and method for coating to polypropylene materials using the promotor
    Patent number: 6479163
    Abstract: The water base adhesion promotor for polypropylene comprises: a grafted polypropylene chloride, which includes a polypropylene chloride moiety and a maleic anhydride moiety as bonded thereto, and which has a chlorine content of 15˜25 weight % and a maleic anhydride moiety content of 1˜5 weight %; an amine-neutralized water-soluble resin; a wettability-improving agent; and water; and is characterized by having: a combination ratio of 25˜90 weight % as of the grafted polypropylene chloride to the total of the grafted polypropylene chloride and the amine-neutralized water-soluble resin; a combination ratio of 2.5˜6.0 weight % as of the wettability-improving agent to the entirety of the promotor; and a solid content of 2˜10 weight % of the entirety of the promotor.
