Melamine resins for stoving enamels, coil coating and wood-based panels — from the global leader in amino crosslinkers.
Amino crosslinkers react during stoving with the functional groups of the base resin and build a dense network. That is where the hardness, chemical resistance and weathering resistance of stoving systems come from — properties a self-drying system does not reach.
The degree of methylation is the central lever: highly methylated grades (HMMM) need more acid catalysis and a hotter stoving window, partially alkylated ones react earlier and more self-directed. Pot life, oven curve and formaldehyde balance all follow from it. Where low-formaldehyde grades are required — for wood-based panels and laminates, for instance — that becomes a selection criterion of its own.
What matters when choosing
Degree of methylation: reactivity, catalyst demand and stoving temperature all depend on it
Available stoving window in temperature and time
Acid catalyst and the resulting pot life
Low-formaldehyde grades where emission limits apply
Compatibility with the base resin and its functional groups
Storage stability of the mixed system
