ES-770 is a high-quality grinding fluid designed for ferrous metals and their alloys. This product has good lubrication, rust prevention, cleaning, antibacterial and other characteristics; This product is completely soluble in water and the working fluid is not affected by oil leakage. This product does not contain mineral oil, sulfur, chlorine, phenol, mercury, phosphorus, nitrite, and other substances, and its environmental indicators meet European industrial standards. At the same time, excellent lubricity and cooling performance are more prominent when cutting alloy materials, which is helpful to solve problems such as chip adhesion, tool wear, etc., thus obtaining extremely high surface quality.

1不含亚硝酸盐、酚类物质，对人体安全。不含油，不易变质，工作废液处理简单。 

2优良的冷却润滑性、冲洗性、沉降性、渗透性，减少屑末粘结。 

3极佳的抗菌性能，因具有抗微生物侵入能力故不需要额外加入杀菌剂，从而大大延长集液槽中工作液的使用寿命。 

4 pH值稳定，防锈性好，对工件有保护作用，不腐蚀工作机械。

Method of using：

1. Before using ES-770 fully synthetic grinding fluid, tap water or appropriate clean water should be used to thoroughly clean the existing metal working fluid, chips, and dirt in the storage tank and equipment.

2. Preparation method: Dilute the product in a certain proportion with clean tap water and stir evenly.

3. Recommended concentration: Grinding: 4%~8%, and the concentration can be adjusted according to the material and processing requirements of the workpiece.

4. During use, the grinding fluid may become dirty due to continuous pollution. If there is too much floating oil and iron filings, it should be cleaned in a timely manner. If the grinding fluid turns black or produces a strange smell, it should be discharged and updated. Depending on the amount of grinding work, the cutting fluid needs to be discharged and updated every 3 months. The pH value and concentration of the tank fluid should be regularly monitored, and ES-770 fully synthetic grinding fluid should be supplemented appropriately to maintain the necessary concentration.

Notes：

1. If this product undergoes layering or thickening at colder temperatures, its performance will not change; But before use, the product needs to be heated to room temperature and stirred well before use.

2. If the prepared grinding fluid is left unused in the machine tool for a long time, the tank fluid should be regularly circulated and oxygenated.

3. Due to the high temperature in summer, the service life and rust prevention period of grinding fluid will be shorter than other seasons. Please be careful when using.

4. This product should be stored in a dry, cool, and ventilated warehouse. During storage and transportation, it should be avoided from sunlight and rain, and the storage temperature should be 0-40 ℃. Under normal storage conditions, the shelf life of the product is 1 year.
