Properties

Technical Details & Test Data

Catalysis Information
  • In baking enamels, CYMEL U-1050 resin does not need 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.
  • If catalyst addition is required, then 0.5 - 1.0% of CYCAT® 4040 catalyst based on total resin solids is recommended for baking schedules of ~125°C for 15 minutes.
  • For wood coating formulations, 6 - 10% Cycat 4040 catalyst on total resin solids of the formulation is sufficient to obtain fast drying behavior at room temperature.
Technical Data
  • CYMEL U-1050 resin is a very effective crosslinking agent for backbone polymer resins containing hydroxyl, carboxyl, and amide functional groups, such as those found on alkyd, polyester or acrylic resins.
  • CYMEL U-1050 resin has a high reactivity and a high tendency for self-condensation providing fast drying films with very good gloss, hardness, stackability and adhesion properties. Although the optimum level of CYMEL U-1050 resin in a given formulation should be determined experimentally, ratios of 25-35%, based on resin solids, are typically most effective over a range of polymer backbone resins.

Storage & Handling

Storage Conditions
  • CYMEL U-1050 resin has a shelf life of 48 months from date of manufacture when stored at temperatures between 5°C and 30°C.
  • Although low temperatures are not detrimental to stability, the viscosity of the product will increase making the resin more difficult to pump or pour.
  • Product viscosity can be returned to normal by gentle re-warming, however, care should be taken to avoid excessive localized heating as this can cause polymerization.
