Although the German chemical company will not reveal the solvent's composition, it says that SolvonK4 is halogen-free and has a KB Value (KBV) of 75 - exceeding that of hydrocarbons with a KBV of 25 and cyclosiloxane D5 with a KBV of 13.
Kreussler adds that SolvonK4 is the only bipolar organic solvent available in textile care, so making it effective against fats, oils and resins and also water-soluble soiling.
SystemK4 also includes a dedicated detergent, ClipK4, a brushing agent, PrenettK4 and a water- and stain-repellent, VinoyK4.
Kreussler has partnered with Bologna-based FMB Group - manufacturers of the Union, Realstar and Firbimatic brands – for ready-to-use machines.
SystemK4 has been undergoing field tests in Europe and the USA since autumn 2009. The company claims that feedback has been positive, with perc users pleased by the cleaning performance on water-soluble soil, while businesses already using HCS technology or other halogen-free alternative solvents remarked favourably about cleaning performance and the ecological advantages.
The system also provides lower energy expenditure for distillation and drying says Kreussler, as well as cost savings in the disposal of distillation residues. The solvent has also passed toxicological, dermatological and mutagenic testing without incident.
