摘要:
To provide a method for producing a pigment dispersing resin varnish for cationic electrodeposition paint, wherein the flow properties and appearance of the resulting electrodeposition coating film are not compromised when using as a solvent a compound that is not volatilized into the atmosphere but remains in the electrodeposition coating film during the onium conversion of a pigment dispersing resin, as well as a cationic electrodeposition resin composition allowing HAPs to be eliminated and volatile organic carbon compounds to be reduced (VOC reduction). A method for producing a pigment dispersing resin varnish for use with cationic electrodeposition paint, wherein a solvent comprising a polyalkylene oxide compound represented by the following formula is used to produce a resin varnish which has been obtained from a cationic epoxy resin composition having amino groups, phosphonium groups, or sulfonium groups. (where R is an ethylene group or propylene group; Ph is a phenylene group; and both n and m are a number of 1 or more).

A cationic electrodeposition coating composition which contains a plasticizer is provided, which does not cause poor adhesion with intermediate and top coats, and allows the VOC content to be reduced. The cationic electrodeposition coating composition of the present invention is a cationic electrodeposition coating composition which contains a cationic group-containing epoxy modified base resin, a blocked isocyanate curing agent and a plasticizer, wherein the plasticizer is a propylene oxide oligomer with an average molecular weight of 200 to 1500, contains a primary hydroxyl group on the repeating terminals of the propylene oxide, and contains one or two primary hydroxyl groups and/or primary amino groups in the molecule.
摘要:
Cathodic electrodeposition paints of the type in which a cationically modified epoxy resin is crosslinked with a blocked polyisocyanate crosslinker are disclosed. The paint contains a cationically modified epoxy resin having at least one oxazolidone ring in the molecule and a Tg ranging between 0.degree. C. and 35.degree. C., and a blocked alicyclic polyisocyanate. The use of lead based anticorrosive pigments may be eliminated or substantially reduced. When the alicyclic polyisocyanate is a bicycloalkane polyisocyanate, the use of organic solvent may also be reduced.
