Hydroxymethyl
Introduction
This type of product is mainly made by hydroxymethylation reaction of melamine and formaldehyde with different molar ratios. The finished product is a crystalline monomer with triazine ring structure, and the main groups are hydroxymethyl and imino groups. It has excellent curing and crosslinking properties and can react with various groups. It is widely used as a crosslinking agent in rubber, coatings, paper, textiles and other fields.
