Synkon APX 180 kg, synthetic metalworking fluid concentrate for grinding and machining, water-based coolant 3–10%, corrosion protection from 3%, low foaming, ISO 6743/7 L-MAH

Synkon APX 180 kg is a synthetic metalworking fluid concentrate designed to prepare a water-based cooling and lubricating solution, suitable for grinding processes and also for machining operations. When mixed with water it forms a transparent, stable solution with low foaming tendency, delivering good wetting and corrosion protection already from a 3% concentration.

Advantages and unique features

• Synthetic concentrate with corrosion inhibitors and additives improving lubricity and anti-foam performance.
• Excellent wetting and easy washability of the working solution.
• Low foaming tendency – stable operation of the coolant system.
• Corrosion protection from a 3% concentration.
• Hard-water resistant – suitable for preparing solutions even with water hardness up to 40°N.
• Free from oils, nitrates, nitrites, chlorinated additives, boron compounds, and primary/secondary amines.

Properties and applications

• Application: cooling and lubricating fluid for grinding; due to good lubricity it can also be used for machining.
• Recommended working concentration: 3–10%.
• Corrosion protection: from 3% concentration.
• Industry example: grinding of steel balls in the bearing industry.
• Workpiece materials: steel, stainless steel, cast iron, sintered carbide, copper, aluminium (per compatibility table).
• Aluminium compatibility: neutral towards EN-AW 1050, EN-AW 2017A, EN-AW 5083, EN-AW 7075 alloys.
