摘要： Cathodically depositable electrodeposition paint binders comprising the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, optionally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde. The binders have excellent corrosion resistance and crosslink to provide coating films at relatively low stoving temperatures without splitting off of substances harmful to the environment.

摘要： Cathodically depositable electrodeposition paint binders comprising a mixture of (A) 95-50% by weight of the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, optionally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde; and (B) 5-50% by weight of an addition component which is substantially water-insoluble under the conditions of electrodeposition and being compatible with Component A. The presence of Component B in the binder provides increased resistance to corrosion, improvements in the surface quality of the stoved films, and enhanced crosslinking of the binder.

摘要： Cationic paint binders based on polyether urethanes are formed by selective reaction of one NCO-group of a diisocyanate which contains NCO-groups of different reactivities with the primary hydroxyl groups of a polyhydroxypolyether in the presence of 1,4-diazabicyclo-2,2,2-octane (DABCO) as catalyst, and subsequently reacting the remaining NCO-group of the diisocyanate with a secondary amine. The binders which are largely free of low molecular basic by-products are used for formulating paints, particularly cathodically depositable electrodeposition paints, which are water-dilutable after protonation.

摘要： Cathodically depositable paint binders, water-soluble upon neutralization with acids, and the method of preparing the paint binders based on amine-epoxy adducts which crosslink at elevated temperature through polyurethane formation are described. The paint binders are prepared by reacting per mole of expoxide groups of a polymer having an epoxy equivalent of between about 180 and 1500 from about 3 to 70 mole percent of a polyisocyanate adduct having substantially no free NCO content and carrying per molecule at least one carboxyl group. Basic functionality is provided by reacting the epoxy-containing polymer, before or after reaction with the polyisocyanate adduct, with secondary aliphatic amines and/or alkanol amines. The binders, in addition to providing stable aqueous solutions when neutralized with an inorganic or organic acid, have good resistance to corrosion and solvents.

摘要： Cationic synthetic resin binders free of epoxy groups for the formulation of electrodeposition paints are described. The binders are the reaction product of an epoxy resin carrying at least two epoxy groups and having an epoxy equivalent of 190 to 1000, with from 0.1 to 1.0 amino groups per available epoxy group of a secondary amine carrying carboxylic acid amide groups. Upon being crosslinked on stoving with a suitable hardening component, the binders have improved water dilutability, permitting a reduction of the degree of neutralization necessary for electrodeposition application and improved intercoat adhesion to addition coats. These improved characteristics are significant with respect to an increase of current yield and in adhering additional coatings of a paint system.
