Cathodically depositable paint binders based on the reaction product of epoxy resins and secondary amines carrying carboxylic acid amide groups |
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.
