No. While all polymers have a small amount of defoamer in them needed for the polymerization process, few, if any besides Forton® VF-774, add it at a level required to meet the requirements of GFRC. Forton® VF-774 was developed specifically for GFRC and adds enough defoamer to meet the requirements of GFRC related to high sheer mixing, pumping and spraying.
