Cathodically depositable electrodeposition paint binders based on epoxy resin-amino adducts reacted with phenol and formaldehyde modified with an unsaturated, substantially water-insoluble component |
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.
