- Formulation Stability
- The stability of solvent-borne systems containing CYMEL® 370 Resin can be enhanced by the addition of primary 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.
- For best stability in waterborne systems, a pH between 7.5-8.5 should be maintained using tertiary amines only.

- Catalysis Information
- CYMEL® 370 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.
- Backbone Polymer Selection
- CYMEL® 370 Resin contains a combination of methoxymethyl and methylol functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, and amide functional groups, such as those found on alkyd, polyester or acrylic resins.
- Although the optimum level of CYMEL® 370 Resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effective.

Storage & Handling
- Storage Conditions
- CYMEL® 370 Resin has a shelf life of 3 years from 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.
