- Formulation Information
- The stability of formulated systems containing CYMEL® 3745N 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 acheive optimum stability.

- Catalysis Information
- CYCAT® 3745N resin reacts according to the specific acid catalysis mechanism, consequently it will respond best to sulfonic acid catalysts, like CYCAT® 4040 or the blocked version CYCAT® 4045 catalsyt.
- 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.
- 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® 3745N Resin contains mainly methoxymethyl functionalities 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.
- CYMEL® 3745N Resin is very compatible with a wide range of backbone polymers and provides films with very good hardness, flexibility, formability, adhesion and resistance properties. Although the optimum level of CYMEL® 3745N Resin in a given formulation should be determined experimentally, its effective equivalent weight will be typically in the range of 130-190.

Storage & Handling
- Storage Conditions
- CYMEL® 3745N Resin has a shelf life of 3 years from the date of manufacture when stored at temperatures between 5℃ and 30℃..
- 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.
