Abstract:
A process for preparing a liquid, partially alkoxymethylated melamine crosslinker composition containing less than 0.5 weight percent free formaldehyde based on 100 percent solids and less than 6 weight percent N-substituted methylol groups based on 100 percent solids, comprising the step of contacting a liquid partially alkoxymethylated melamine crosslinker starting material having greater than about 0.5 weight percent free formaldehyde based on 100 percent solids and greater than about 6 weight percent N-substituted methylol groups based on 100 percent solids, and a reagent selected from the group consisting of an amino group containing compound and an etherification agent, said contacting being carried out at a temperature and length of time sufficient to produce a liquid partially alkoxymethylated melamine crosslinker containing less than 0.5 weight percent free formaldehyde based on 100 percent solids and less than 6 weight percent N-substituted methylol groups based on 100 percent solids.
