H-7325 Amino Crosslinker
H-7325 Amino Crosslinker is a methanol-etherified, high-imino melamine formaldehyde resin, characterized by an average of three imino groups per melamine ring, which gives it high reactivity. Its excellent compatibility with acrylic, polyester, and alkyd resins makes it versatile for use in a variety of coating systems. The resin provides coatings with high hardness and high gloss, along with exceptional resistance to salt spray, gasoline, and acidic or basic environments, ensuring durability and protection in harsh conditions.
>H-7325’s partial water solubility makes it particularly well-suited for formulating waterborne baking paints, offering both performance and environmental benefits in coating applications.
