Application Industry: Metal Cutting Liquid
Product Name: Antifoam RK-747
RK-747 uses silicone grease system, with special emulsion system. It provides excellent antifoaming performance and balance, which make sure the compatibility of system, diluted stability and excellent stability of shear. It’s suitable for metal cutting liquid. Little addition can achieve ideal foam control effect and reduce the negative effect on the final products due to adding lots of defoamer. It is used in full synthetic cutting liquid ad emulsion type cutting liquid.
Product property:
Particularly suitable for adding in cutting fluid systems
Very low dosage
Strong alkali resistance, long-lasting antifoaming
Excellent stability of storage and shear
Main physical and chemical properties:
Item | Index |
Appearance | Milky-white liquid |
Viscosity (25°C) | 150~400mPa ·s |
Solid content | 30 ± 1% |
PH | 6.0-8.0 |
Application Process:
Can be directly added or diluted in the foaming system and need to make sure dispersion. The diluted emulsion is recommended to be used up in a short period of time to maintain its optimum performance. If it’s diluted, please use it within four hours.
In general, the dosage is around 1-20ppm for different temperature and stirring, which can achieve the ideal result. The pre- experiments are needed to optimize the dosage.
According to specific application environment, RK-747 can be used with RK-783 together to achieve the best effect.
Key Applications
Full synthetic or emulsion cutting liquid system
Other circular shear system
Industries with high requirement of diluted stability
