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
