Catalysis Information
  • CYMEL 27-802 resin does not require the addition of an acid catalyst to the formulation to obtain effective cure at normal baking conditions.
  • The acidity of the primary film former is usually sufficient to initiate the curing process.
  • The cure can be additionally catalyzed by weak organic or inorganic acids, such as CYCAT® 296-9 catalyst, which has proved to be very effective for these systems.
  • Recommended levels are 1.0-2.0% on total resin solids for baking schedules of 110°C-150°C for 15 to 20 minutes

Technical Details & Test Data

Technical Data
  • CYMEL 27-802 resin is a very effective crosslinking agent for backbone polymer resins containing hydroxyl, amide, and carboxyl functional groups, such as found on alkyd, polyester or acrylic resins.
  • In addition to crosslinking, CYMEL 27-802 resin has a high tendency for self-condensation providing films with very good flow, gloss, hardness, adhesion, exterior durability and chemical resistance properties.
  • Although the optimum level of CYMEL 27-802 resin in a given formulation should be determined experimentally, ratios between 25% and 35% based on resin solids are typically most effective.

Storage & Handling

Storage Conditions
  • CYMEL 27-802 resin has a shelf life of 12 months 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.
