- Dosage Information
- CYMEL® 325 is useful in polyester and acrylic resin coil coating systems, where a minimum amount of weight loss and a high build without the danger of solvent popping during cure is desirable.
- Since CYMEL® 325 does self-condense to some extent, some sacrifice in flexibility should be expected.
- CYMEL® 325 is therefore recommended for prefinished metal applications where shorter dwell times or lower temperature cures are required and postforming is not of a critical nature.
- The following formulation for a White, High Gloss, Coil Coating Enamel illustrates this application of CYMEL® 325
- Product Applications
- Automotive enamels
- General purpose enamels
- Coil coating
- High solids coatings
- Water-borne coatings
