HOC UT 4940 is recommended for heavy duty machining of a wide range of aerospace materials including aluminium alloys (series 2000 and 7000 in particular), high alloy steels and difficult aerospace materials such as titanium and nickel alloys.
The product is suitable for both centralised systems and single­sump machines while the advanced boron-free technology extends emulsion life without the need for regular biocide treatments.
The versatile formulation is designed to give low foam in soft water.

• High lubricity: sophisticated package of mineral oil and polar additives extend tool-life
• Very long sump-life: new HOC UT 4000 series emulsion technology extends intervals between clean outs
• Very stable emulsion : fewer additive treatments and lower usage costs
• Inhibits aluminium staining : can be used for sensitive alloys eg 7000 series
• Very low foaming : ideal for the highest speeds and pressures in soft water
• Excellent EHS profile : Boron, formaldehyde, chlorine and Phenol-free. Contains only TRGS 611 approved amines

• Concentrate Appearance – Amber oil
• Specific Gravity@ 20°c – 0.93
• Refractometer Factor – 1.05
• Emulsion Appearance  – Milky white
• pH in Use  – 8.9-9.5

Medium duty machining 6-8 %

Heavy duty machining 8-10 %
