Castrol Techniclean SF is a water-based, mildly alkaline industrial process cleaner formulated with biodegradable surfactants and corrosion inhibitors.
Castrol Techniclean SF is designed for intermediate and final cleaning of components and parts made of ferrous and non-ferrous metals and can be used in a wide range of spray and flood washing machines (e.g. IFW systems).
Castrol Techniclean SF is particularly recommended where good temporary corrosion protection during intermediate storage is required.
The product effectively removes residues from water-miscible metalworking fluids, light cutting and stamping oils, lubricating oils, oily viscous corrosion protection films and general contamination.
Application conditions
- Concentration range: 0.5 – 5 %
- Temperature range: ambient temperature – 80 °C
- Spray pressure: up to 300 bar*
*Depending on bath temperature and water quality, significantly higher spray pressures may be applicable.
Benefits
- Leaves a thin temporary corrosion protection film after drying – helps minimise scrap and improves productivity
- Good demulsifying properties support easy oil separation and long bath life – helps reduce maintenance and disposal costs
- Low foaming at ambient temperature enables cold start-up – economical and helps reduce energy costs
- Contains biodegradable surfactants – improves the environmental profile of the application
- Versatile, compatible with many metals and usable in soft and hard water – supports product consolidation
Typical properties
- Appearance: clear, yellowish liquid
- Density at 15 °C: 1070 kg/m³
- pH (2% in deionised water): 9.7
- Total alkalinity: 10.4 mg KOH/g
- Corrosion protection (IP 287): 3% (rating 0)
Concentration check
- Titrate with hydrochloric acid (0.1 mol/l) using Nitrazingelb indicator
- Calculation: concentration in % = ml of HCl used × factor 0.45
- Alternative: Castrol Mini-Lab (Nitrazingelb indicator) factor 0.5
Storage
- Keep the container tightly closed to avoid contamination
- Protect from frost, store cool and dry, avoid direct sunlight
- Recommended indoor storage temperature: 5 °C to 45 °C
- Please observe the Safety Data Sheet
FAQ – Frequently Asked Questions
What is Castrol Techniclean SF used for?
For intermediate and final cleaning of ferrous and non-ferrous metal components in spray and flood washing systems.
Which residues can Techniclean SF remove?
Residues from water-miscible metalworking fluids, light cutting and stamping oils, lubricating oils, oily corrosion protection films and general dirt.
Does Techniclean SF provide corrosion protection?
Yes. After drying, it leaves a thin temporary corrosion protection film, especially useful during intermediate storage.
What are typical operating conditions?
0.5–5% concentration, ambient temperature up to 80 °C, and spray pressure up to 300 bar (higher may be possible depending on bath temperature and water quality).
