- Catalysis
CYMEL UB-30-B 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 UB-30-B resin can be enhanced by the addition of alcohols, amines or a combination of these. Low molecular weight primary alcohols such as ethanol and 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.; STORAGE STABILITY; CYMEL UB-30-B resin has a shelf life of 24 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 irreversible viscosity increase

- Backbone Polymer Selection
CYMEL UB-30-B 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 UB-30-B resin in a given formulation should be determined experimentally, ratios between 25% and 35%, based on resin solids, are typically most effective
