PROCESS FOR PRODUCING UREA GROUP CONTAINING RESOL-CURABLE PAINT BINDERS

摘要

1949/US-2730 A process is described for producing urea group containing paint binders, curable with resols, particularly suited for the formulation of top grade CED-primers. The products are resol-modified epoxy resin amine adducts, the resol segments of which are obtained through reaction of NH-group containing aminoalkylation products of phenols with isocyanate compounds. The substituted urea groups improve the adhesion properties and, in particular, to the adhesion of additional layers of paint.
