CYMEL® 254 resin

Technical Datasheet | Supplied by allnex
CYMEL® 254 resin by allnex is a highly reactive, methylated/n-butylated high imino melamine formaldehyde crosslinker. It is very effective for backbone polymer resins containing hydroxyl, amide, and carboxyl functional groups. It is suitable for medium to high-solids systems, primer formulations and general industrial- & automotive coatings.
  • It exhibits low formaldehyde release and adhesion properties.
  • It has a slightly lower butoxymethyl content and higher molecular weight compared to CYMEL® 202, resulting in a faster cure response while maintaining the hydrophobicity of the film.
  • As compared to other high imino melamine resins, it possesses superior stain-, water- and corrosion-resistant properties.
  • It has a high tendency towards self-condensation reactions at rather low baking temperatures, providing films with very good hardness, gloss, chemical resistance and outdoor durability.
  • It shows very good compatibility with alkyd- & polyester resins and good compatibility with acrylic- & epoxy resins.
  • The recommended dosage level of CYMEL® 254 resin is 25-35% based on resin solids.
  • It has a shelf life of 1 year.
