High Imino type Resin
MELCROSS 25 can be used as a Cross linking agent for medium solid or water borne finishes, Automotive or general metals finishes, Coil or container coatings.
This resin is a 78-82% solids in iso-butanol, High viscous liquid.
MELCROSS 25 resin is a high degree methylated melamine formaldehyde crosslinking agent with a high imino functionality.
And a low methylol content and high imino functionality resin is a very effective crosslinking agent for epoxy, alkyd, polyester or acrylic resins. Delivers medium solids coatings.
MELCROSS-25 amino resin is a very effective crosslinker for backbone polymers containing hydroxyl, amide and carboxyl functional groups, such as epoxy, alkyd/polyester or acrylic resins. Partially soluble in water and has an excellent compatibility with water soluble polymers. Suitable for coil coating and industrial paint of baking enamels, providing less weight loss during the baking process. Fast cure response, Higher resistance properties, No strong acid catalyst required.
MELCROSS 25 resin is suitable for a wide range of industrial stoving systems, providing less weight loss during the backing process in comparison with the partially methylated melamine crosslinking agents. This makes MELCROSS-25 resin suitable for medium solids coating formulations.
This resin also provides fast cure response, higher resistance properties, and no strong acid catalyst required in the normal baking enamel systems.
Formulated systems containing MELCROSS-25 resin have to be stabilized with primary alcohols, amins or with a combination of these materials.
Acid catalyzed coatings may be cured as low as 110-150°C for 20-30 minutes.
