Product Introduction
Application Industry: Metal Cutting Liquid Semi-synthetic Cutting Liquid Emulsion Cutting Liquid
Product Name: Antifoam RK-7670M
RK-7670M uses silicone grease system, with special emulsified method. It provides excellent defoaming performance and balance, which makes sure the compatibility of system, dilution&shear stability. Little addition can achieve ideal foam control results and reduce the negative effects on the finished products due to adding a large amount of antifoams. It is widely used in metal working liquid, semi & full synthetic cutting liquid and emulsion type cutting liquid.

Application Process
Can be directly added or diluted in the foaming system and need to make sure dispersion. The diluted solution is recommended to be used up in a short period of time to maintain its optimum performances. If it’s diluted, please use it within 4 hours.
Generally speaking, the add amount is around 1-20ppm for different temperature and stirring, which can achieve the ideal result. The pre- test is needed to optimize the dosage.
According to specific application conditions, RK-7670M can be used with RK-783 together to achieve the best effect.
Key Applications
Metal cutting liquid, semi or full synthetic or emulsion cutting liquid system
Other circular shear system
Industries with high requirement of diluted stability
