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.
