- Formulation Stability
- The stability of formulated systems containing CYMEL® 301 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 DMEA or 2-AMP at a concentration of 0.5 1.0% on total resin solids.
- Package stability can also be enhanced by the use of a blocked acid catalyst, such as CYCAT 4045 catalyst.
- For waterborne systems, pH should be adjusted between 7.5-8.5 to achieve optimum stability

- Catalysis Information
- Because of its high extent of alkylation, CYMEL® 301 Resin responds best to sulfonic acid catalysts, like CYCAT® 4040 catalyst or CYCAT 600 catalyst.
- Generally, 0.5 to 1.0% of CYCAT 4040 catalyst on total resin solids of the formulation is sufficient to provide good cure at normal baking schedules (15-20 minutes at 120-150°C) in solvent-borne systems.
- Water-borne systems generally require temperatures of 150°C or higher to effect cure.
- Higher concentrations of catalyst might be necessary if there are basic pigments or additives present in the formulation.
- Backbone Polymer Selection
- CYMEL® 301 Resin contains mainly methoxymethyl functional sites making it a highly effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, or amide functional groups, such as those found on alkyd, polyester, or acrylic resins.
- Its high monomer content and low tendency to self-condense results in films with high flexibility and formability when paired with inherently flexible polymers, such as polyester resins.
- The effective equivalent weight of CYMEL® 301 Resin typically ranges from 130-190, however, its optimum loading should be determined experimentally for each formulation with consideration of the performance properties to be optimized.

Storage & Handling
- Storage Conditions
- CYMEL® 301 Resin has a shelf life of 5 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
