- Catalysis Information
- Because of its high extent of alkylation, CYMEL® 303 LF 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.
Technical Details & Test Data
- Technical Data
- CYMEL® 303 LF 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 result in films with high flexibility and formability when paired with inherently flexible polymers, such as polyester resins.
- The effective equivalent weight of CYMEL® 303 LF is typically 130 - 190 g/eq, 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® 303 LF resin has a shelf life of 1800 days from the date of manufacture when stored at temperatures below 32°C.
- Although low 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.
- WARNING: CYMEL® 303 LF resin may turn hazy when cold due to crystallization of hexamethoxymethylmelamine (HMMM).
- Warming will return the product to normal with no adverse impact on performance.
