RK-170A is mainly use the mineral oil with large spreading coefficient and hydrophobic particles as anti-foaming active materials, supplemented by anti-foaming synergistic substance. Mineral oil increases the spreading speed of anti-foaming particles, and the hydrophobic particles reduce the entry barrier of anti-foaming particles. The interaction between these two provides great anti-foaming performance. Meanwhile, mineral oil has good affinity with organic matter, so it doesn’t cause surface defect.

RK-207 is a high efficient liquid(wetting) defoamer based on new polymer, which is combined with active antifoaming carrier oil components. It’s effective for fine resin emulsion and added into any processes of latex paint production, it’s also suitable for polymerization processes. Also, it has high compatibility with the system, no precipitation and formation of shrinkage cavities on the surface.
