International Classification:

C09D12328

US Classification:

427302, 427314

Abstract:

The water base adhesion promotos 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 15Ë25 weight % and a maleic anhydride moiety content of 1Ë5 weight %; an amine-neutralized water-soluble resin; a wettability-improving agent; and water; and is characterized by having: a combination ratio of 25Ë90 weight % as of the grafted polypropylene chloride to the total of the grafted polypopylene chloride and the amine-neutralized water-soluble resin; a combination ratio of 2. 5Ë6. 0 weight % as of the wettability-improving agent to the entirety of the promotor; and a solid content of 2Ë10 weight % of the entirety of the promotor. The method for coating to polypropylene materials comprises: a pretreatment step in which the polypropylene material is beforehand cleaned and then the above water base adhesion promotor is applied, and then dried; and a coating step in which a paint is coated to the material after the pretreatment step.
