- Formulation Stability
- The stability of baking enamels containing CYMEL® UI-27-EI 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 n-butanol.

Technical Details & Test Data
- Catalysis Information
- CYMEL® UI-27-EI 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.
- 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.
- In one-pack acid curing finishes, weak inorganic acids, such as CYCAT 296-9 catalyst, are strongly recommended.
- Backbone Polymer Selection
- CYMEL® UI-27-EI Resin is a very effective crosslinking agent for backbone polymer resins containing hydroxyl and carboxyl functional groups, such as alkyd, polyester or acrylic resins. CYMEL® UI-27-EI Resin has a high reactivity and a high tendency for self-condensation.
- Although the optimum level of CYMEL® UI-27-EI Resin in a given formulation should be determined experimentally, ratios between 25% and 35%, based on resin solids, are typically most effective in a range of polymer backbone resins.

Storage & Handling
- Storage Conditions
- CYMEL® UI-27-EI Resin has a shelf life of 720 days from date of manufacture when stored at temperatures below 32°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 warming, however, care should be taken to avoid excessive localized heating as this can cause polymerization.
