Liquid degreasers

Pragolod 13 is a liquid, highly efficient alkaline surfactant degreaser of a high passivating capability suitable for cleaning of steel, cast iron, glass and ceramic ware. The agent contains adsorption corrosion inhibitors which may impart both inter-operation as well as temporary corrosion protection to the steel parts to be degreased.

The agent is appropriate for the inter-operation degreasing and for machine cleaning, e.g. in the WAP devices or in cleaning desks in the machine repair shops. It may be even used at lower application temperatures and, therefore, as an alternative to solvent degreasers including chlorinated ones at hand-assisted and machine cleaning.

Pragolod 14 is particularly suitable for the degreasing and cleaning of the steel and cast iron substrates between two subsequent technological operations and should be applied by spraying. It contains low-foaming surfactants and, hence, is convenient to be especially used for machinery cleaning, e.g. in the WAP spraying machines or in cleaning desks in the shops. Furthermore, it may be alternatively applied for cleaning at lower temperatures and, therefore, for both machinery as well as hand-assisted cleaning operations as a replacement for solvent-based degreasers including chlorine hydrocarbons. To boost the anticorrosion protection affect of the agent, its elevated concentration within 3 – 5% and drying without a preliminary rinse should be employed. Pragolod 14 is a liquid alkaline agent for combined technological operations degreasing together with surface passivation and is formulated on the basis of both low-foaming surfactants of high biodegradability and corrosion inhibitors. It should be particularly used for both spraying and immersion degreasing of steel and cast iron substrates and tumbling of ferrous metals. Besides, it may be used for passivation of ferrous metals after pickling or other technological operations in water – based agents if an active steel surface is needed to be pasivated. Pragolod 14 is completely free of any inorganic components which otherwise might cause salt deposits on the cleaned but still unrinsed surface. It is also applicable for the passivation of the ferrous surfaces after other degreasing operations, pickling in acids or tumbling operations of steel parts together with the passivation. At the agent formulation, both low foaming and passivating efficiency were emphasized and, therefore, compared with the similar agents of, however, enhanced foamability such as Pragolod Grato 12, Pragolod 13 or Pragolod 44, displays a slightly inferior degreasing performance. Pragolod 14 is a clear colourless or yellowish alkaline liquid (pH value within 10 – 11) completely miscible with water, the clouding point of the 5% bath being about 33 – 38°C and the pH value about 10.

Pragolod 16 is a liquid weakly alkaline water-based degreasing and washing agent containig blend of highly effective surfactants, phosphates, water softeners and and corrosion inhibitors for cleaning steel and cast iron parts from the hygrophobic soils such as conservation oils, waxes, greasing emulsions, pastes etc.

It is suitable for the degreasing operations in industry and should be applied by ultrasonic-assisted immersion, or spray in the degreasing lines and machines as well as at the deconservation operations by mobile pressure cleaning machines such as Wap, Karcher etc. To be further used for the degreasing of both final parts and semi-products, mobile machines and other technological equipments of industrial plants. The special additives contained prevent undesirable leaching of cobalt from the cleaned parts made of sintered carbides and tool steels. The typical feature of the agent is its deemulgation activity which results in rapid separation of the released oils and soil on the degreasing bath surface. Capable to remove the solid particles of graphite and carbides from the surface cleaned.

Operating conditions

Nearly neutral surfactant degreaser suitable for the degreasing of steel, cast iron, copper and aluminium and its alloys and painted surfaces by immersion, spraying, wiping and ultrasonic-assisted techniques.

Pragolod 20 UF is a versatile liquid degreaser suitable for the cleaning of steel, cast iron, aluminium and its alloys, copper and its alloys and, to a limited extent, painted surfaces. The chemical composition of the agent enables a continuous regeneration of the degreasing bath by ultrafiltration and microfiltration.

Running conditions of the bath

Liquid acid-based degreaser suitable for the cleaning of austenitic stainless steel, copper and its alloys and precious metals and their alloys by immersion or immersion with ultrasonic assistance. The agent contains a larger amount of biodegradable surfactants capable to remove strongly stuck residues of grinding or polishing pastes.

Running conditions of the bath

Liquid strongly alkaline and medium emulsifying degreaser suitable for the bath regeneration by a grease skimming technique or microfiltration. Suitable for immersion, spraying or ultrasonic-assisted applications of steel and cast iron.

Pragolod 44 is a liquid degreaser suitable for cleaning and degreasing of steel, cast iron and, to a limited extent, of aluminium and its alloys. It is in general applicable for cleaning of painted surfaces as well but, with regard to the variability of the paints types, a test for paint durability in contact with the degreaser should be carried out at first. The agent contains components which may impart both corrosion protection at the following machinery operations as well as temporary corrosion protection to the steel parts to be degreased. As far as the subsequent surface treatment operation allows, the overall passivating effect of the degreaser may be even enhanced by its incorporation into the final rinse until the approximate pH value 10 of the rinse is reached. The agent is a liquid of yellowish-to-brownish colour, classified as irritant with respect to the valid legislation, and containing a blend of both inorganic as well as organic components and non-ionic surfactants of good biodegradability. The surfactants contained are of high performance and low foamability so that could be conveniently used for the applications by immersion, spraying, high-pressure and ultrasonic-assisted degreasing.

A liquid weak alkaline degreaser and cleaner convenient, for the degreasing of steel, cast iron, aluminium and copper and their alloys.It is also applicable for the cleaning of painted and chromated zinc electroplated surfaces. It contains low-foaming surfactants and, therefore, may be used for the applications by immersion, spraying, high-pressure cleaning through the WAP device, ultrasonic-assisted degreasing, industrial degreasing in containers, chambers as well as through degreasing machines.

Running conditions of the bath

Liquid degreaser for a rough cleaning of steel and cast iron by water pressure cleaning machines. The composition of the agent ensures removing of thicker impurities of hydrophobic character off the surface.

Running conditions of the bath

A liquid, mild alkaline water-based degreasing and washing agent suitable first for cleaning of all kinds of both metallic (steel, cast iron, copper and aluminium and their alloys etc.) and non-metallic (glass, ceramics, plastics) surfaces from hydrophobic impurities, such as preservative oils, waxes, lubricating emulsions, pastes etc. by mobile pressure cleaning machines (e.g. WAP, Karcher, Kranzle etc,).
Besides that, application of the agent by spraying or immersion techniques in industrial degreasing lines and machines as well as for hand washing, is possible. In general, it can find its use for cleaning of both final as well as semi finished products, machinery and equipment in services, industry and shops.

All-purpose, very efficient liquid alkaline degreaser with a moderate passivating effect. It is predominantly suitable for immersion degreasing of both steel and cast iron. It contains non-ionic and easily biodegradable surfactants.
