- Formulation Information
The stability of formulated systems containing CYMEL® 3020 resin can be enhanced by the addition of alcohols, amines or a combination of these. Low molecular weight primary alcohols such as methanol 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. Package stability can also be enhanced by the use of a blocked acid catalyst such as CYCAT® 4045 catalyst. For waterborne systems, a pH of 7.5-8.5 should be maintained to achieve stability.

- Catalysis Information
CYMEL® 3020 resin will respond best to sulfonic acid catalysts, like CYCAT®® 4040 catalyst or the blocked version CYCAT® 4045 catalyst. Generally, 0.5 to 1.0% catalyst solution on total binder solids of the formulation is sufficient to provide good cure for industrial formulations at baking schedules of 20 minutes at 120°C to 160°C. For electro deposition formulations, a cure schedule of 20 minutes at 150°C and higher is advised. Higher concentrations of catalyst might be necessary if there are basic pigments or additives present in the formulation.
- Backbone Polymer Selection
CYMEL® 3020 resin contains mainly methoxymethyl and butoxymethyl functionalities making it a very effective crosslinker for backbone polymer resins containing hydroxyl, amide or carboxyl functional groups, such as found on alkyd, polyester or acrylic resins. CYMEL® 3020 resin is hydrophobic in nature and compatible with a wide range of backbone polymers providing films with very good appearance, adhesion and resistance properties. Although the optimum level of CYMEL® 3020 resin in a given formulation should be determined experimentally, its effective equivalent weight is in the range of 160-220.

Storage & Handling
- Storage Conditions
CYMEL® 3020 resin has a shelf life of 4 years the date of manufacture when stored at temperatures between 5°C and 30°C. Although lower temperatures are not detrimental to stability, its viscosity will increase, possibly making the resin difficult to pump or pour. The viscosity will reduce again on warming, but care should be taken to avoid excessive local heat, as this can cause an irreversible increase in viscosity
