Iso-Butylated melamine formaldehyde resin Amino resin

Haminol 3123 resin is a commercial grade of Iso butylated melamine formaldehyde resin with a medium degree of alkylation, a medium methylol content, low imino functionality, medium molecular weight and viscosity.

Haminol 3123 provides very fast cure response, excellent flow, flexibility, alkali resistance, adhesion properties at general industrial stoving applications.

Haminol 3123 melamine resin is a usefull crosslinking polymer for the other polymer resins which containing hydroxyl, amide and to some extent, carboxyl functional groups, such as alkyd, polyester, or acrylic resins.

And has a high reactivity and a high tendency for self- condensation in a range of basic polymers, providing films with very good hardness, gloss, chemical resistance and exterior durability.

A low acid number in an alkyd or acrylic resin is sufficient. The cure reaction can be additionally catalyzed with weak organic or inorganic acids such as maleic, citric, phosphoric, or alkyl phosphoric acids, low levels of para toluene sulfonic acid catalyst.

Acid catalyzed coatings may be cured as low as 110-150°C for 15-20 minutes.

To control the stability, you can use primary alcohols or tertiary amins for neutralization and PH adjustment
