Mineral Oil-based Defoamer

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. ​

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-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-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-980P is a 100% active content mineral oil antifoam. It’s very high efficiency, great persistence and compatibility, which is suitable for acrylic acid, vinyl acetate, acetic acid, styrene-acrylic, copolymer emulsion, coating, resin, detergent, sewage treatment. ​

RK-40S is a multi-purpose silicone synthetic defoamer for non-aqueous systems. It is particularly suitable for foam control in oil-based inks for printed circuit boards and epoxy floor paint systems. It has good defoaming properties and can quickly eliminate small bubbles. ​

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-700P is a non-silicon defoamer mainly composed of modified polyether. It has the characteristics of good dispersibility in water and strong dynamic antifoaming ability. It is mainly used in power plant desulfurization, fermentation, water treatment, desalination, landfill leachate, PCB cleaning, water glass, etc.. ​

RK-012B is a 100% active defoamer, which has good defoaming properties against styrene/acrylic acid, pure acrylic emulsion, PVA, and water-based epoxy. It is especially suitable for addition during the grinding process of water-based color paste. ​

RK-30C is made by using special modified silicone polyether system. Compared with the traditional defoaming agent, it maintains good stability and high temperature performance in the system. It’s suitable for gear oil, high temperature boiling point distillation, asphalt production , benzene extraction process, transportation and other high temperature solvent foaming systems. ​

RK-1215A is a silicone defoamer, which is stable in high temperature and shear, acid system, especially the performance of fast defoaming. It’s suitable for textile printing&dyeing, industrial cleaning, metal working liquid, and other high&mid temperature, high shear, and extremely pH environment. ​

RK-9864 is a special polysiloxane and polyether copolymerization defoamer with special structure of the active synergist. It has strong anti-foaming performance in polyurethane, acrylic emulsion system, wood furniture coatings, architectural coatings, automotive production line coatings, paper coatings, sealant and adhesive, especially suitable for paint mixing phase foam control, with excellent comprehensive performance. ​

RK-8777 is a modified silicone defoamer specially designed and developed for latex systems. It has excellent anti-foaming performance and good compatibility.It is suitable for wood furniture paints, architectural coatings, industrial coatings, overprint varnishes and other systems in water-based systems. ​

T70 is a high solids and nonionic hydrophobically modified ethylene oxide urethane (HEUR) rheology modifier designed for waterborne architectural, industrial and functional coatings. It is APEO and OrganoTin free. ​

RK-83S is a emulsion type polyether modified organic antifoam. Compared to traditional defoamer, it is stable under strong acid, high temperature, high shear system. It has good defoaming & antifoaming performance, and safe to use. RK-83S is suitable used in the pesticide industry, textile printing&dyeing production processes, especially in high temperature overflow dyeing processes. It can also used in other typical high temperature, high shear, extreme pH environments. ​

RK-7600 is a polyther(ester) defoamer in paper industry. ​
