CYMEL® 325 is a new type of highly methylated melamine-formaldehyde resin which does not require a strong acid catalyst for fast cure response. CYMEL® 325 is reactive with hydroxyl-, amide-, and carboxyl-group-containing polymers. The weight loss of CYMEL® 325 during the baking process is significantly less than that of partially methylated melamine-formaldehyde resins. The baking volatiles from CYMEL® 325 contain very low levels of formaldehyde. The lower weight loss of CYMEL® 325 crosslinked coatings also results in less tendency to blister at higher film thickness. CYMEL® 325 requires only weak acid catalysis for cure; a low acid number in the backbone resin is sufficient. The cure reaction additionally can be catalyzed with weak organic acids or inorganic acids such as maleic, citric, phosphoric, or alkyl phosphoric acids, low levels of p-toluene sulfonic acid, or CYCAT® 14040 catalyst. CYMEL® 325 will self-condense, like a partially methylated resin. Higher film hardness may, therefore, be obtained by raising the level of amino crosslinking agent. The high reaction rate of CYMEL® 325 at lower temperature reduces the chance of evaporation of low molecular weight resin components. CYMEL® 325 should, therefore, be very suitable for applications where "smoking" of the baking exhaust is a problem. Compared to partially methylated melamine-formaldehyde resins, CYMEL® 325 has shown, in some water-reducible coatings, improved humidity and salt-spray resistance. CYMEL® 325 resin is FDA approved under section 121.2514 and 121.2526.
