- Product Properties
AFCONA-2028 prevents the formation of foam and blisters during the manufacturing and application of solvent-based wood finishes. AFCONA-2028 is particularly suitable as a defoamer for curtain coatings as well as during production. When foam causes a problem during packaging, AFCONA-2028 can be added slowly, while stirring to speed up the bubble breaking process. In this case, AFCONA-2028 is more user-friendly and easier to handle than AFCONA-2022, because it is less sensitive to crater formation and other well-known defoamer side effects.
AFCONA-2028 can be used in:
1) polyurethane coatings for wood, plastic and car refinish
2) unsaturated polyester systems
3) acid curing coatings for wood
4) NC lacquers for wood coatings and general industrial
