- Catalysis Information
- CYMEL 328 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 minutes at 120-150°C).
- If catalyst addition is required, then 0.5-1.0% of CYCAT® 296-9 catalyst based on total resin solids is recommended.
Regulatory & Compliance
- Certifications & Compliance
- Contains any chemicals listed on Prop 65 (including impurities, residues, catalysts, monomers, and by-products and excluding heavy metals)?
Technical Details & Test Data
- Technical Data
- CYMEL 328 resin contains a combination of methoxymethyl, methylol and imino functionalities making it a very effective crosslinker for backbone polymer resins containing hydroxyl, amide and carboxyl functional groups, such as alkyd, polyester or acrylic resins.
- CYMEL 328 resin is very reactive and has a tendency to self-condense at normal baking temperatures, providing films with very good hardness, flexibility, gloss, chemical resistance and outdoor durability.
- CYMEL 328 resin is very good compatible and stable with a wide range of waterborne polymer systems.
- Although the optimum level of CYMEL 328 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effectiv

Storage & Handling
- Storage Conditions
- CYMEL 328 resin has a shelf life of 6 months 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.
- Beware of freezing
