General description
Hellmanex III significantly reduces the surface tension of water. The removal of dirt particles is also assured by the good wetting action of a Hellmanex III aqueous solution, while its high emulsifying and dispersing capabilities prevent the redeposition of the loosened particles. Special surface-active substances facilitate the residue-free rinsing of the optical components once they have been cleaned.
Hellmanex III is filtered to 1 μm and is therefore virtually free of solid particles.

Application
The optimal dilution (usually 0.5 to 2 vol-%) depends on several factors, such as the hardness of the water, the degree and type of contamination, the temperature, etc. The use of demineralised water improves the cleaning characteristics.
An increase in temperature speeds up the cleaning process. However, at high temperatures it is necessary to avoid thermal shock. The cells should be pre-warmed before being submerged into hot cleaning solutions.
Hellmanex III, when diluted to its working concentration of 2%, is suitable for use with glass, quartz, sapphire, porcelain, ceramics, plastics, and ferrous metals. It can also be used, with some limitations, on metals that are sensitive to corrosion such as aluminium and other non-ferrous metals. In such cases, avoid prolonged application. In the case of materials not listed here, suitability tests should be carried out or enquiries directed to Hellma.
The concentrate can be stored in vessels made of stainless steel, PE, PP, PVC, FPM, or NBR.
