摘要： Cathodically depositable paint binders based on epoxy resin/amine adducts modified with diamine bridges which carry longer-chained substituents are described. The diamine bridges are the reaction products of diprimary amines and mono- and diepoxy compounds. The modified epoxy resin/amine adducts have low viscosities and low glass transition temperatures in spite of their high molecular weights. The stoved films, even with higher film thickness, have flawless surfaces and excellent mechanical properties.

摘要： Cationic paint binders based on the reaction products of epoxide compounds with substituted carbamic acid derivatives and the use thereof in the formulation of cathodically deposited paints are described. The carbamic acid derivatives are urethanes, ureas, allophanates, and biuret compounds. Crosslinking functionality and/or protonatable groups are introduced by a suitable selection of blocking agents for the isocyanate compounds utilized. The reaction between the epoxide compounds and carbamic acid derivatives takes place in the presence of basic groups under relatively mild conditions; and, even when several carbamic acid moieties are present in a molecule, a readily soluble product is obtained.

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.

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.
