DF-603 defoamer polyether modified silicon
DF-603 defoamer is a water-dispersible silicone defoamer made from polyether modified silicon as the main raw material. It is a defoamer product specially developed for metalworking fluid concentrates to control foam. Defoaming and anti-foaming ability is good. It has strong versatility and can still maintain good defoaming and antifoaming capabilities at high temperature and high shear forces.
Main characteristics and advantages of DF-603 defoamer
*Good defoaming and antifoaming performance.
*The compatibility and stability in the formula are good, and the dispersion in water is good.
*The amount is small and does not affect the basic properties of the foaming system.
DF-603 defoamer is mainly used in metal processing liquid systems.
DF-603 defoamer can be added directly to the concentrate of metalworking fluid, and then stirred slightly to ensure complete dispersion and uniformity.
The recommended amount to be added to metalworking fluids: 0.05-0.3%.
Packaging and storage
DF-603 defoamer is shipped in 25-liter plastic drums with a net weight of 25 kg. Or shipped in 200-liter plastic drums with a net weight of 200 kg.
Product application，How to use
In order to ensure product quality, the container should be tightly sealed when not in use. It should be stored at conventional room temperature and avoid long-term exposure to extreme hot and cold environments, as it may cause product stratification. If the product is layered, stir before use. If the product is frozen, it needs to be heated and thawed, and stirred after thawing.
The shelf life of the product is six months.

Shanghai Milin Chemical Co., Ltd. was registered and established in Shanghai, China in early 2006. In 2010, Shanghai Haolin Chemical Co., Ltd. was founded in Jinshan, Shanghai, and in 2022, Haolin (Weihai) New Materials Co., Ltd. was established in Shandong. Since its establishment, Milin and Haolin Chemical have been dedicated to the research and production of cutting fluid additives for over a decade. We focus on independent research and production rather than acting as agents for foreign brands; we emphasize core competitiveness rather than expanding our product range by stocking market goods. We advocate for quality over quantity. Milin Chemical is labeled as a domestic manufacturer of cutting fluid additives rather than a trader. Compared to our competitors, our product range is less than one-tenth of theirs. However, our quality and prices are highly competitive. Milin is a genuine additive manufacturer.
At the beginning of its establishment, Milin Chemical was the first in China to independently develop and produce biocide BK and biocide MBM, which remain the brands of mainstream cutting fluid manufacturers in the country. In 2010, Milin Chemical achieved independent production of ternary carboxylic acid rust inhibitors, with key performance close to advanced international levels. In 2014, Milin Chemical developed an aluminum corrosion inhibitor with performance comparable to mainstream foreign products, with an additive dosage as low as 0.4%.
Milin Chemical has many years of experience in the development, research, and on-site application of metalworking fluids and additives, offering unique insights into additive recommendations and production technology based on application formulas. Our products include: lubricants, biocides, rust inhibitors, defoamers, phosphate ester aluminum alloy corrosion inhibitors, and other single agents.
Currently, Milin Chemical has become a long-term partner of major domestic metalworking fluid manufacturers, witnessing the development of China's independent metalworking fluid brands!
