HOCUT 4260 is advanced, low to medium duty, boron-free and formaldehyde-free emulsion technology giving very long sump-life.
A special additive package gives greatly enhanced machining performance and extends too life, compared to conventional products. HOC UT 4260 is particularly effective on machining aerospace airframe structural components in aluminium alloys, titanium alloys or fiber composites.
This product holds the following approvals and conformities – Airbus AIMS 12-10-000 and 80T-30-4010 • ASTM F483 ; ASTM F1110; Table A7.1 AIPI 01-02-003 • Aluminium Elementary Parts NCF1378 AIPI 03-11-001 • Conforms to the requirements – Boeing BAC 5008 cat 5 & 6 conform
– Bombardier BAMS 569-001 • A, C & D approved
– Dassault approved
– SAFRAN Aircraft Engines• PR 6300, approved on all materials
– SAFRAN Equipment (Messier Dowty) approved PCS 4002

HOCUT 4260 is recommended for low to medium duty machining including high speed of a wide range of aerospace materials including aluminium alloys (series 2000 and 7000 in particular), fiber composites, but also ferrous alloys. HOCUT 4260 is suitable too for grinding applications.
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 and no soaps in soft to hard water (10°dH – 70 °dH cumulated hardness)
Its operator-friendly EHS profile and its non-staining & corrosion-free properties make HOCUT 4260 particularly efficient on aero structural airframe components. An advanced antiwear additive extends the tool life too.

• Versatile : can process very various materials, ranking from fiber composites, to aero aluminium alloys as well as ferrous alloys
• High detergency : leaves clean parts and working environment
• Extended tool life: thanks to antiwear additive package tool wear is minimized, saving tooling costs
• 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 to hard water (10°dH – 70°dH)
• Excellent EHS profile : boron, formaldehyde, chlorine and phenol-free. Contains only TRGS 611 approved amines
