What are the structural features in the melamine monomer that lead to the very high hardness of cured melamine resins?
What will be an ideal response?
The melamine monomer has three amine groups attached to the ring, with each amine group containing a nitrogen and two hydrogens. Each of these nitrogens is capable of being a crosslinking site. Therefore, the hardness in melamine plastics comes from the very high crosslink density that is possible because of the multiple crosslink sites.
