BONDERITE S-FN 6748-23 kg
Product description:
BONDERITE S-FN 6748 is an aqueous temporary corrosion protection agent applicable in spray and immersion processes from 15 °C upwards. It is composed of organic corrosion protection components and stabilizers against water hardness precipitation. Change of colour is caused by raw material and has no Impact on performance.
Application Areas:
Passivation of steel and cast iron for subsequent storage in closed warehouses. BONDERITE S-FN 6748 is used in immersion and spray systems, especially in the last stage of multiple zone systems.It also can be used for:
● Water for leak testing hollow parts, e.g. radiators, fuel tanks, intake manifolds, cooling systems and silencers
● Cooling water circuit on engine test benches
● Cooling water for induction hardening
● Mildly alkaline solutions as well as neutral cleaner solutions for improving the corrosion protection.
Directions for use:
Preliminary Statement:
Prior to use it is necessary to read the Material Safety Data Sheet for information about precautionary measures and safety recommendations. Also, for chemical products exempt from compulsory labeling, the relevant precautions should always be observed. Please also refer to the local safety instructions and contact Henkel for analytical support.
Bath Make-up:
Add the required amount carefully to the circulation system.Concentration on steel 5 to 20 °C Concentration on Aluminium 15 to 30 g/L
Operating Data:
Temperature 15 to 80°C Duration of treatment 0.5 to 3 min Longer duration of treatment as mentioned above may cause discolouration on non-ferrous metals.
Bath Control:
BONDERITE S-FN 6748 solution is controlled by titration of total alkalinity. Feed, mL 100 mL Titrant: 0.5 N hydrochloric or 0.5 N sulphuric acid End point: pH 3.6 Indicator: Methyl orange Titration factor (TF): 0.81
- With a pipette transfer 100 mL bath solution into a clean 300 mL Erlenmeyer-flask.
- Add 4 to 5 drops of indicator.
- Titrate the solution with 0.5 N hydrochloric or 0.5 N sulphuric acid.
- The endpoint will be shown by a colour change from orange to red (pH: 3.6).
- Multiply the consumption of the acid solution with the titration factor (TF), to get the concentration in g/L
- Divide this by 10 to get the value in %.
Storage:
Recommended Storage Temperature : 0 to 40°C Shelf-life, months : 24 Frost-Sensitive : yes
Parameters:
Appearance : clear, bright yellowish liquid Density at 20°C, DIN 51757 : ~1.03 g/cm³ pH (1 % solution) : ~11.0
