CYMEL® 1158

CYMEL® 1158 resin is a n-butylated, high imino melamine crosslinker which combines the excellent compatability of a conventional butylated melamine resin with the fast, low temperature cure response of CYMEL® 325 resin. Like other high imino melamine resins, CYMEL® 1158 has a high tendency to selfcondense resulting in films with high film hardness that can be adjusted based on loading. It’s hydrophobic nature improves susbstrate wetting, flow and leveling, and humidity and salt spray resistance making it suitable for a wide range of applications including automotive topcoats and general industral finishes

Technical Details & Test Data

Technical Data
  • CYMEL 1158 resin is an 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 1158 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.
Catalysis Information
  • CYMEL 1158 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® 296-9 catalyst based on total resin solids is recommended.

Storage & Handling

Storage Conditions
  • CYMEL 1158 resin has a shelf life of 2 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
