Processing & Availability
- Additional product information
- AFCONA-2722 also acts as a leveling agent, giving a smooth surface to the coating. In epoxy coating, combination with AFCONA – 2038 will increase the defoaming performance tremendously. AFCONA – 2722 is recommended for:
- Additional product information
- 1) Solvent-free as well as solvent containing 2 pack epoxies. For solvent-based epoxies, normally AFCONA – 2725 will perform better.

- 3) Unsaturated polyesters
- Additional product information
- 0.5 - 1.5% on total formulation. In general under normal conditions, the dosage is 1.0% for solvent-free system and 0.5% for solvent-based system, based on total formulation. For serious case combination of AFCONA – 2722 and AFCONA – 2038 at 1% each will solve most of the foam problem.
- Additional product information
- AFCONA-2722 can be incorporated prior to processing. If added subsequently, good distribution must be insured.
- Additional product information
