Amino resin Haminol325GW
Haminol325GW resin is a highly imino-partially methylated melamine formaldehyde resin, using isobutanol as a solvent
Product Description
Haminol 325GW resin is a high-imino partially methylated melamine formaldehyde resin, using isobutanol as a solvent. This product has a lower degree of alkylation compared to Haminol 25G resin. It exhibits good water solubility and high reactivity, enabling rapid curing without strong acid catalysts. It is generally used as a highly efficient crosslinking agent for water-based baking paints, roll coatings, or can coatings with medium solid content. It also serves as a highly efficient crosslinking agent for epoxy, alkyd, polyester, and acrylic resins. This product is highly water-soluble and can be used in water-based coatings.
