A semi-synthetic, nitrite free, biostable, extreme pressure soluble metal working fluid.

Product Description

Sigma TSSM is a semi-synthetic water soluble cutting fluid with considerable advantages over conventional soluble oil emulsion based products. The formulation includes an EP package together with lubricity additive and is cresol, phenol and nitrite free. Sigma TSSM forms a green opalescent emulsion which is biostable and long lasting even in very hard water.


Sigma TSSM is recommended for all arduous machining operations, and especially those in CNC machines, manufacturing centers and centralised systems. It is suitable for most materials including high tensile steels, yellow metals and aluminium. Can be used for gear cutting, broaching and threading.

Features and Benefits

Contains no carcinogens

Sigma TSSM does not contain any known carcinogenic ingredients such as nitrites, phenols and cresols thus improving occupational health.

EP and Lubricity Package

The formulation includes an EP and lubricity package, ensuring improved finish comparable with neat oils in many applications. The additive package by providing lubrication at the tool tip improves tool life and reduces built up edge.

Biostable Opalescent Emulsion

The emulsion being biostable ensures freedom from bad odours and long life, whilst the opalescent emulsion allows visual examination of the work piece.

Low Foaming

The emulsion has a low foaming tendency.

Contains Powerful Corrosion Inhibitors

Sigma TSSM contains superior corrosion inhibitors giving outstanding rust protection with no sticky residue or sludge deposits on the machine.

Stable in All Waters

Sigma TSSM forms stable emulsions even in very hard water leading to easily maintained working fluid.

Packing, Storage and Handling

Sigma TSSM is available in 5, 20 and 210 litre drums. The containers should be stored inside protected from frost and out of direct sunlight. The 210 litre drums should be stored on their side to prevent water ingress if outside.


Sigma TSSM should be added to well agitated water, never add water to the product.
