Polymer Quenching Fluid KR9988
Due to the absence of inverse solubility, the cooling rate of the quenching medium can be adjusted by increasing its operating temperature, providing the medium with broader application versatility.
Product Details
Advantages
● No inverse solubility, ensuring stable cooling performance;
● Flexible cooling control through concentration adjustment to meet various heat treatment requirements;
● Excellent rust and corrosion protection for workpieces, quenching tanks, and circulation systems;
● Superior stability against aging and degradation, extending service life;
Smoke-free and non-flammable, eliminating fire risks and maintaining a clean production environment;
● Eco-friendly formulation with low environmental impact.
Technical Specifications
| Model | KR9988 |
|---|---|
| Appearance | Light yellow to pale reddish viscous liquid |
| Typical Viscosity | (40℃, 10%) mm²/s 3.19 |
| Operating pH Value | (5%) 9.5-10.5 |
| Typical Applications | Suitable for large-size workpieces with medium to low hardenability, including 30CrMo, 40CrNiMoA, and 42CrMo steels, such as vehicle-mounted gas cylinders. Also applicable to spring steels (50CrV, SUP9), tool and die steels, and martensitic stainless steels. |
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. |
