Product Description

Partially methylated melamine resins are highly methylated or partially alkylated resins that cure satisfactorily at 120-150°C without the addition of a strong acid catalyst. In thermoset coating systems, the acidity of most polymers is sufficient to catalyze the reaction, and the film properties are similar to those of the high imide resins. In addition, functional polymers containing hydroxyl, carboxyl and amide groups can be reacted with, but these resins are also susceptible to self-condensation and have an R.E.C. of 180-240 As with all melamine resins, they can be stabilized in formulations by the addition of amine and alcohol solvents The greatest limitation of these products is baking. The biggest limitation of these products is the high formaldehyde release during baking, which is mainly due to the high free methoxyl content.
