Application method
As a non-ionic defoaming agent, 8802 exhibits exceptional compatibility with cationic and anionic surfactants as well as polymer systems, without forming complex precipitates. For instance, during polyvinyl chloride suspension polymerization, it can be added to the system either alongside the terminator or pre-added to the terminator before termination.
Defoaming agent 8802 can be added directly or diluted with cold water before use, with the water temperature preferably kept below 35°C.
Recommended dosage: 0.02-0.025‰ of PVC.
