Abstract
Advanced, etherified aminoplast resins containing one or more guanamine residues are prepared by heating, at a pH of from 2.5 to 9, an etherified methylolated urea, cyclic urea, carbamate or melamine such as methylated methylolated urea, ethyleneurea, or propyleneurea with a guanamine, such as benzoguanamine or acetoguanamine. The products may be heated with resins containing at least two alcoholic hydroxyl, carboxylic acid, or carboxylic acid amide groups per molecule to form hard, crosslinked materials. They are particularly useful in forming surface coatings.
