Product Details
Advantages
Excellent lubrication and cooling performance, effectively protecting tools and enhancing surface quality | Maintains good low-foam characteristics in most machining applications, meeting foam requirements for high-pressure internal cooling systems | Superior corrosion inhibition for aluminum alloys, while also providing rust protection for workpieces and machine components | Free from chlorine, phosphorus, sulfur, phenols, formaldehyde-releasing biocides, nitrites, heavy metals, and other harmful substances, making it safe and environmentally friendly | Good biostability, effectively inhibiting microbial growth and extending the service life of working fluids in both centralized and single-machine fluid supply systems.
Technical Specifications
| Model | KR-C8210 |
|---|---|
| Concentration | (wt,%) 5-15 |
| Product Features | Excellent Lubrication |
| Application Range | Cutting automotive precision aluminum parts, especially where high lubrication and low foaming are required. |
Storage Conditions
| Item | Requirements |
| Storage Temperature | 5–40°C. Indoor storage is recommended. Protect from freezing, as freezing may damage the polymer system. |
| Packaging & Container Requirements | Packaged in 200 L plastic drums with a net weight of 200 kg per drum; 25 kg plastic pails or 1,000 kg intermediate bulk containers (IBCs) may also be used. |
| Shelf Life | 2 years. After expiry, the product may only be used after it has been retested and confirmed to meet specifications. |
| Key Properties (KR9988) | Appearance: light yellow to pale red viscous liquid; pH (5% solution): 9.5–10.5; kinematic viscosity (10% solution at 40°C): 3.19 mm²/s. |
| Precautions | Nonflammable and presents no fire hazard; nevertheless, keep the container tightly sealed. If stored outdoors, place the drum horizontally to prevent water, dust, and other contaminants from entering. Retighten the cap immediately after dispensing. Check the concentration with a refractometer before use. PAG-containing products exhibit reverse solubility; polymer separation at elevated temperatures is normal, and the product can be restored by cooling and stirring. |
