In accordance with the principle of “like with like”, non-polar cleaning media are used to clean components contaminated with oil, grease, wax or petroleum. A distinction is made between halogenated and non-halogenated solvents, which include various hydrocarbons – as an environmentally friendly alternative to chlorinated hydrocarbons – as well as modified alcohols, including DOWCLENE and Zestron VD.
The advantages of solvent cleaning systems are evident:
As non-halogenated solvents, hydrocarbons (HC) are characterised by optimum cleaning performance, good environmental compatibility and low operating costs.
More...By operating in a vacuum, the hydrocarbons used can also be used above their flash point without additional explosion protection measures; the higher temperature improves the cleaning and drying results. They are used particularly successfully for very demanding cleaning tasks such as fine or ultra-fine cleaning.
Modified alcohols are generally characterised by good material compatibility, so that they can be used for parts made of practically all metals.
More...At the same time, cleaning is carried out without corrosion, oxidation, discolouration, chemical burns, matting or other damage to the surface.
The two products mentioned below in particular have proven themselves for use in solvent cleaning systems.
It is a modified alcohol and has both lipophilic (fat-loving) and hydrophilic (water-loving) properties.
More...This achieves good results when cleaning off oils and greases as well as when removing polar substances such as emulsions and fingerprints.
The distillable and non-corrosive DOWCLENE 1601 dries quickly and residue-free from surfaces. Typical application areas include cleaning before heat treatment, coating, welding, vacuum brazing and bonding.
Its polar and non-polar components make it particularly suitable for water-free applications without water rinsing.
More...It can be distilled uniformly, can be used with steam rinsing under vacuum and is free of tensides, which guarantees residue-free drying. It is therefore used to clean water- and pH-sensitive parts such as electronic assemblies, ceramic substrates and lead frame-based, discrete components in closed-loop processes.
