Description

ROKAfenol PN 7K is a specialist anionic additive for industrial applications. This product is a phosphorus ester of oxyethylated nonylphenol of acidic character. It is in the form of a homogeneous colourless to light brown liquid. The acid value of this product is in the range 90-130 mgKOH/g. The freezing point is close to 0°C. 

ROKAfenol PN 7K is poorly soluble in water – forms cloudy solutions in it. At a concentration of 1% of the product in water, an emulsion with a pH in the range of 2-3 is formed. ROKAfenol PN 7K serves as an ingredient for obtaining washing and cleaning agents and as an emulsifier. It works in aqueous and non-aqueous systems containing other surfactants, mineral oils, vegetable oils and organic solvents. It is an active agent that retains its cleaning properties in cold and hard water. ROKAfenol PN 7K is resistant to high temperature and high concentration of electrolytes. It has excellent resistance to oxidizing and reducing factors and is stable in acids and alkalis.

The product is recommended for washing and degreasing of cheviot, yarns, woollen fabrics without alkali additives and as a penetrator and equaliser in dyeing, peeling off and finishing fibres. It is a component of antistatic compositions. It also works as an emulsifier of oils, solvents, silicone greases, in order to prepare process preparations for spinning, carding and other operations, for all types of vegetable, animal, chemical and mixed fibres.

The ability of ROKAfenol PN 7K to dissolve in oil and the extreme pressure properties of the product are useful in lubricants and metalworking formulations. In waterborne metalworking fluids, the product is used in neutralised form. Triethanolamine salt provides optimal protection against corrosion in both water and oil systems. The product can be used in cutting and grinding fluids as well as in aqueous hydraulic fluids. Due to its lubricating properties, it can be used in the production of e.g. greases for chain belts and transmission oils.

Regulations of the European Union – Regulation of European Parliament and Council (EC) No. 648/2004 of March 31, 2004 on detergents – restrict the use of the product to industrial cleaning, textiles and leather processing and metal working with closed loop system, where the working fluid is recycled or burnt.
