ABSTRACT:
Described is a liquid, partially alkoxymethylated melamine crosslinker composition having from about 2.6 to about 4.6 moles of combined formaldehyde per mole of melamine, from about 1.4 to about 4.4 moles of alkyl per mole of melamine, from about 1.3 to about 3.4 moles of NH per mole of melamine, a free formaldehyde level of less than about 0.5 weight percent based on 100 percent solids, and an N-methylol level of less than about 6.0 weight percent; processes for its preparation; a low formaldehyde emitting curable composition containing the crosslinker; as well as a method of coating a substrate and substrates so coated.
