Non-chlorinated industrial solvent cleaner for safe removal of dirt, oil, grease and other contaminants

Clarea® HC40 is an aliphatic hydrocarbon based low odour degreasing solvent with a flash point of 40°C. It will remove oils, greases, hydraulic fluids cutting fluids and a wide variety of hydrocarbon based protective coatings. It can be used as dip, brush or in hand-wipe process. It has a relatively fast evaporation rate and is most suited to hand wipe and small immersion tanks.

Clarea® HC40 is compatible with all metals and many plastics and other composite materials.

• To reduce solvent losses keep containers closed.
• Dip tanks should have a suitable close fitting lid which should be closed when not in operation.
• Stubborn soils can be worked with a brush.
• Excess solvent can be removed with cloth.
• Allow components to air dry in ventilated area.
• Blowing air over the components will aid drying.

Suitable equipment which can be used with Clarea® HC40 is shown here.
