Key Features

72-Hour Salt Spray Protection (ASTM B117): Verified zero pitting or staining on ferrous metals after 72 hours of continuous testing at a 10% emulsion concentration.

60-Day Humidity Resistance (ASTM D1748): Prevents flash rust for over 60 days in high-stress warehouse environments (100% relative humidity at 49°C) to protect indoor inventory.

450 ppm Hard Water Stability: Formulated to resist oil-water separation, skimming, and hard-water scum in heavy industrial water conditions up to 450 ppm calcium carbonate (CaCO₃) equivalent.

Sump Life: Maintains working fluid pH between 8.8 and 9.3 while rapidly separating slide-way lubricants for mechanical skimming to prevent fluid breakdown.

Machining Compatibility & Application

Ferrous & Alloy Steel Optimization: Formulated for cast iron, carbon steels (AISI 1018 to 1045), and high-strength alloy steels (4140 and 4340 grades).

Mixed-Metal Galvanic Protection: Prevents galvanic corrosion and surface staining during cross-production runs involving aluminum alloys (6061, 7075) and yellow metals (brass and copper).

Elastomer Compatibility: Verified compatible with standard Viton, Nitrile, and NBR seals to prevent seal swelling or hardness degradation in machine tools.

Batch Traceability

24-Month Audit Retention: Each drum and IBC tote is laser-etched with a unique lot code. A 500-milliliter physical retention sample is stored for 24 months.

Shipment-Specific CoA: Every delivery includes a digital Certificate of Analysis (CoA) verifying exact batch viscosity, pH, Brix, and FTIR chemical consistency.

Compliance & Certifications

EU REACH SVHC Compliance: Every batch is tested against the latest ECHA Candidate List, guaranteeing Substance of Very High Concern (SVHC) concentrations remain below 0.1% (w/w).

Global Market Access: Documented compliance with EU REACH, US TSCA, and RoHS Directive 2015/863 (RoHS3) to ensure seamless customs clearance for international supply chains.

GHS & OSHA Logistics Safety: All containers feature GHS-compliant labeling meeting OSHA Hazard Communication Standard (29 CFR 1910.1200), accompanied by full 16-section SDS documentation.

ISO 9001: 2015 Quality Control: Formulated in an ISO 9001 certified facility utilizing digital weight-batching systems that maintain a strict ±0.1% blending tolerance for reliable rust preventive film thickness.

FAQ

Q: What dilution ratio is recommended for different machining operations?

A: For light-duty machining, a 5–6% emulsion is typically sufficient. Heavy-duty cutting or applications requiring longer rust protection generally perform best at an 8–10% concentration.

Q: How is product quality handled if a shipment does not meet specifications?

A: If laboratory testing confirms that the delivered product does not meet the agreed specifications, replacement material or another mutually agreed solution is normally arranged within 5–10 working days.

Q: What is the shelf life of the unopened concentrate?

A: When stored in sealed original containers between 5°C and 40°C, the concentrate maintains its performance for up to 24 months. Containers should be protected from direct sunlight and freezing conditions during storage.

Q: Which manufacturing processes commonly use this product?

A: The fluid is widely used in CNC machining, turning, milling, drilling, tube processing, stamping, and short-term storage of finished metal components. It is suitable for production lines handling both ferrous and non-ferrous materials.

Q: What packaging options are available for international shipments?

A: Standard packaging includes 20-liter pails, 200-liter steel drums, and 1,000-liter IBC totes. Custom private-label packaging and bulk container shipments can also be arranged for OEM and high-volume customers.

Q: What technical documents are provided before shipment?

A: Customers receive a complete documentation package including TDS, SDS, Certificate of Analysis, and product labeling compliant with destination market requirements. Additional export documents such as Certificate of Origin can be supplied upon request.
