RK-707 is mainly made of mineral oil with large expansion coefficient and hydrophobic particles as defoaming active substances, assisted by defoaming synergistic substances. Mineral oil increases the expansion velocity of defoaming particles, and hydrophobic particles reduce the entry energy barrier of defoaming particles. The interaction between the two provides excellent defoaming performance. At the same time, mineral oil has a good affinity with organic matter, so it will not cause surface defects. It is mainly used in the emulsion and latex of water-based coatings, and the adhesive made by the emulsion or latex and waterborne building coatings. The effect is more obvious in the system with higher viscosity. It also can be used in the leather edge oil.

RK-203 is metal soap, wax mineral oil-based defoamer. It is mainly used in paper coating, textile printing, water based architectural paint emulsion and paint made by this emulsion, waterproof coating, etc.

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.

RK-1107 is a 100% active content mineral oil defoamer, which is specially designed for emulsion polymerization, suspension polymerization, emulsion adhesives, etc.. It’s very high efficiency, great persistence and compatibility. It’s also confirmed that it is effective for curtain coating.

RK-170 is mainly use the large coefficient of osmosis of mineral oil and hydrophobic particles as antifoaming active material, supplemented by antifoaming synergistic substance. Mineral oil increase osmotic speed. The hydrophobic particles reduce antifoaming synergistic material into the barriers. The interaction provides great antifoaming performance. Meanwhile, mineral oil has good affinity with organic matter so that it doesn’t cause surface defect.
