Castrol Syntilo 81 E, 20L

Castrol Syntilo 81 E is a synthetic coolant specifically developed for grinding operations on steel components. It forms a transparent and stable solution in both hard and soft water. The fluid provides excellent corrosion protection and demonstrates outstanding resistance to bacterial contamination, making it ideal for centralized systems and individual machine reservoirs.

Application:

Syntilo 81 E is intended for surface and cylindrical grinding using double-disc or centerless grinding machines. It is optimized for consistent performance in high-precision steel component finishing, offering excellent particle settlement and a clean working environment.

Advantages and benefits:

• Low-foaming formula: performs consistently in both soft and hard water conditions.
• Excellent microbial stability: extends service life in central systems and individual sumps.
• Efficient tramp oil rejection: oil floats to the surface and is easy to remove.
• Environmentally responsible: free from chlorine, phenols, and nitrites.
• Reliable corrosion protection: even in high water hardness conditions.
• Fast particle settling: prevents wheel loading and ensures cleaner work zones.

Classification according to standards:

• DIN 51385 – corrosion inhibition for water-miscible metalworking fluids.
• ISO 6743/7 – classification: ISO-L-MAF (fully synthetic fluids for metal grinding).

Approvals and certifications:
Castrol Syntilo 81 E is compliant with industry regulations for environmentally responsible manufacturing. It is suitable for operations where clear coolant appearance, long fluid life, and clean shop conditions are required.
