Effective preservation in metalworking fluids

Effective preservation in metalworking fluids

Effectiveness and stability is highly important for metalworking fluids. But protection against bacteria and fungi is also very critical in these products. With its OPP-based product group, Lanxess ensures effective preservation in metalworking fluids and offers outstanding stability in liquids with high pH values.

As a leading specialty chemicals company, Lanxess offers a comprehensive range of products that enhance the quality and durability of lubricants. The product range of the Additives (ADD) business unit at Lanxess includes synthetic lubricant base oils, lubricant additives, industrial additive packages and finished lubricants that are used over a whole variety of application areas and industries.

A core competence are additives and additive packages for metalworking applications which are finding their use mainly in the automotive, aviation, shipbuilding and primary metalworking industries. Other key areas comprise products for refrigeration systems, food processing, mining and construction. They are used to protect engines and drive trains from wear and extend the service life of machinery.

Metalworking fluids are mostly water-based oil emulsions or solutions of other lubricants. In metal workshops, they are in permanent contact with not only tools and workpieces, but also air and must be protected against decay through bacteria, fungi and yeasts. Otherwise, they soon can turn into putrid waste. Metalworking fluids are therefore preserved with biocides. Lanxess offers Preventol O Extra,  Preventol ON Extra and Preventol OF 45 as effective protection. The products are based on o-phenylphenol (OPP), a mild-acting, stable fungicide, which is resistant even under difficult conditions, such as a high pH or high temperature. It acts on the cell membranes of the microorganisms, without being decomposed by their metabolisms.

As a result, unlike most biocides, Preventol OPP is not consumed when eliminating microorganisms. Its most striking properties are an especially long effective life, good incorporation, outstanding stability in liquids with high pH values and excellent effectiveness even in the parts of a plant that only come into contact with metalworking fluids due to splashing. It is particularly suited to protecting non-synthetically produced, natural, difficult-to-preserve, contaminated substances such as emulsions containing mineral oil that are intended for use as metalworking fluids. OPP is the preferred choice in applications where exposure, i.e. contact with people, plays a role. For example,  it is used in disinfectants and crop protectionagents and, unlike many other biocides, has no sensitizing (allergenic) effect. Despite its high stability, it is biologically degradable.

Being a part of the lubricants industry since 1977, Adco became a distributor of Rhein Chemie products in 1996, and  today it serves customers in the Lanxess distributor network. The company always keeps a product stock and provides technical support for Lanxess customers.
