Method for producing pigment dispersing resin for cationic electrodeposition paint

Amino-polyether-modified epoxy and cationic electrodeposition paint composition containing the same

A cationic electrodeposition coating composition is provided which contains blocked isocyanate curing agent which is blocked with a substance not recognized as a HAPs (hazardous atmospheric pollutant). The cationic electrodeposition coating composition of the present invention contains a cationic group-containing epoxy modified base resin and a blocked isocyanate curing agent, wherein said blocked isocyanate curing agent is obtained by reacting a polyisocyanate compound with, as a blocking agent, a terminal primary OH-containing propylene glycol monoalkyl ether and expressed by the formula RO(CH(CH )CH O) H (where R is an alkyl group having 1 to 8 carbons, which may be branched, and n is 1 to 3).

Cationic electrodeposition coating composition

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.

Cationic electrodeposition coating composition containing plasticizer

The present invention relates to compounds containing an oxamic acid group, which show high reactivity and have stability for water and are used as paints, adhesives, and plastic materials etc. in the form of a reaction material or a resin. Since into these compounds an oxamic acid group is introduced in a part of the molecule and the oxamic acid group is an ionic functional group, the compounds show superior solubility and dispersing character in water and also, since the oxamic acid group is a group of a disappearing type with heating, the compounds do not remain, after hardening, in the hardened product. Accordingly, the hardened products obtained from these compounds are superior in water-resistant and anticorrosion properties and in durability.

Compound containing an oxamic acid group, a process for producing the

The present invention provides a cationic electrocoating composition which cures at the preferred curing temperature range and provides superior curing properties and cured film properties. The cationic electrocoating composition of the present invention comprises a resinous component and an aqueous medium, wherein the resinous component is composed of one or more polymers and has as a whole an active hydrogen containing group, a cationic group and a substituted group and at least one of the polymers comprises a vinyl polymer which has 5 to 1,000 substituted acylamide groups.

Cationic electrocoating composition

An aqueous dispersion coating composition comprising at least one kind of resin, wherein any one of said resin or resins has at least one functional group selected from an active hydrogen-containing group, a substituted acylamide group and a water dispersible or water-soluble group, and wherein the resin composition as a whole contains each of the above described kinds of functional groups.

Aqueous dispersion coating composition

An anodic electrodeposition composition containing a water-soluble or water-dispersible modified epoxy resin derived from an epoxy resin having two epoxide groups and at least one alcoholic hydroxy group at the terminals and the middle of the resin backbone, respectively. The modified epoxy resin has at least one polymeric side chain block bound to said alcoholic hydroxy group and at least one acid group derived from said terminal epoxide group.
