- Formulation Stability
- The stability of formulated systems containing CYMEL® 1123 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 CYMEL® 1123 Resin.
- For waterborne systems, pH should be adjusted between 7.5-8.5 to acheive optimum stability.

Technical Details & Test Data
- Catalysis Information
- CYMEL® 1123 Resin responds best to sulfonic acid catalysts, like CYCAT® 4040 catalyst, CYCAT 600 catalyst, or CYCAT 500 catalyst.
- Generally 0.5 to 1.0% catalyst solution on total binder solids of the formulation is sufficient to provide good cure at baking schedules of 20 minutes at 120°C to 160°C.
- Higher concentrations might be necessary if there are basic pigments or additives present in the formulation.
- Backbone Polymer Selection
- CYMEL 1123 resin contains mainly methoxymethyl and ethoxymethyl functional sites making it a very effective crosslinker for backbone polymer resins containing hydroxyl, amide or carboxyl functional groups, such as those found on alkyd, polyester or acrylic resins.
- The effective equivalent weight of CYMEL 1123 resin typically ranges from 120-180, 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® 1123 Resin has a shelf life of 4 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.
