- Formulation Stability
- The stability of baking enamels containing CYMEL® U-65 Resin can be enhanced by the addition of alcohols, amines or combination of these.
- Low molecular weight primary alcohols, such as n-butanol, are most effective. Recommended amines are TEA, DMEA or 2-AMP at a concentration of 0.5-1.0% on total binder solids. Ambient cure systems are usually stabilized only by addition of adequate amounts of primary alcohol, such as ethanol or butanol.
- For best stability in waterborne systems, a pH between 7.5-8.5 should be maintained.

Technical Details & Test Data
- Catalysis Information
- CYMEL® U-65 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 based on total resin solids is recommended.
- For wood coating formulations cured under ambient conditions, 6-10% Cycat 4040 catalyst on total resin solids of the formulation is sufficient to obtain fast drying behavior.
- Backbone Polymer Selection
- CYMEL® U-65 Resin is a very effective crosslinking agent for backbone polymer resins containing hydroxyl functional groups, such as alkyd, polyester or acrylic resins.
- The optimum level of CYMEL® U-65 Resin in an acid curing wood coating formulation should be in the range of 25-35% on total resin solids.
- To obtain coatings with optimum resistance properties, addition of a melamine resin, such as CYMEL MB-98, at levels of 5-10% on total resin solids is recommended.

Storage & Handling
- Storage Conditions
- CYMEL® U-65 Resin has a shelf life of 4 years 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 an irreversible increase in viscosity.
