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.

Main physical and chemical properties:
Appearance:Light yellow opaque liquid
Viscosity (25°C) :1500~8000mPa ·s
Active content:100%
pH :5.5-7.0
Application Process：
Defoamer consists of hydrophobic liquid and hydrophobic particles. It is recommended that the user should fully stir before using, even if the surface is not stratified; long-term storage may be slightly stratified, evenly mixed and used, without affecting the effect.
The additive amount is 0.2-0.6% of coating weight, added 1.0-1.5‰ at pulping process, added 1.0-1.5‰ again at paint correction. The optimum addition should be depended on specific situation. Do not dilute. If diluted with water, the antifoaming performance will be destroyed.
