ABSTRACT:
Highly methylated methylolguanamines, such as a methylated tetramethylolbenzoguanamine or tetramethylolacetoguanamine, are advanced by heating under acid to neutral conditions with an advancement agent such as benzoguanamine, acetoguanamine, ethyleneurea, 1,3-propyleneurea, melamine, or urea. The products may be heated with resins containing at least two alcoholic hydroxyl, carboxylic acid, or carboxylic amide groups per molecule to form hard, crosslinked coatings. They are particularly useful in powder coatings.
