CYMEL® 380

CYMEL® 380 resin is a partially methylated melamine crosslinker supplied in isobutanol and is a lower solids version of CYMEL® 370 resin. CYMEL® 380 resin is fast reacting and has a high tendency to self-condense resulting in films with high film hardness, gloss, chemical resistance and exterior durability. The high reactivity, combined with high solids content makes CYMEL® 380 resin suitable for a wide range of solventborne and waterborne industrial bake formulations.

Catalysis Information
  • CYMEL 380 resin may not require the addition of an acid catalyst to the formulation to obtain effective cure.
  • In many instances, the acidity of the backbone polymer in the formulation is sufficient to catalyze the reaction under normal baking conditions (15-20 minutes at 120-150°C).
  • If catalyst addition is required, then 0.5-1.0% of CYCAT® 4040 catalyst or CYCAT 296-9 catalyst based on total resin solids is recommended.

Technical Details & Test Data

Technical Data
  • CYMEL 380 resin contains a combination of methoxymethyl and methylol functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, and amide functional groups, such as those found on alkyd, polyester or acrylic resins.
  • Although the optimum level of CYMEL 380 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.

Storage & Handling

Storage Conditions
  • CYMEL 380 resin has a shelf life of 3 years from the date of manufacture when stored at temperatures between 5°C and 30°C.
  • Although lower temperatures are not detrimental to stability, its viscosity will increase, possibly making the resin difficult to pump or pour.
  • The viscosity will reduce again on warming, but care should be taken to avoid excessive local heat as this can cause an irreversible increase in viscosity
