The need to develop water-borne systems with lower levels of organic c
o-solvents con be met by using melamine-formaldehyde crosslinking agen
ts which ore completely water soluble. By controling the distribution
of species within the crosslining agents, the range of performance can
be extended without compromising solubility. Some encouraging results
have been obtained using these products in formulations which are co-
solvent-free.
