Technical Details & Test Data
- Backbone Polymer Selection
CYMEL U-1054 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. It has good compatibility over a broad range of polymer backbone resins providing films with very good flow, gloss, film hardness, and adhesion properties on metal substrates. Although the optimum level of CYMEL U-1054 resin in a given formulation should be determined experimentally, ratios between 25% and 35%, based on resin solids, are typically most effective.2
- Catalysis
CYMEL U-1054 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.
- Stability
FORMULATION STABILITY
The stability of formulated systems containing CYMEL U-1054 resin can be enhanced by the addition of alcohols, amines or a combination of these. Low molecular weight primary alcohols, such as ethanol or n-butanol, are most effective. Recommended amines are TEA or DMEA at a concentration of 0.5- 1.0% on total binder solids.
STORAGE STABILITY
CYMEL U-1054 resin has a shelf life of 365 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 irreversible viscosity increase.
