It is recommended for deposit inhibition in industrial water systems like recirculating cooling systems, cooling towers, waste water streams facing deposition problems, paper mils etc, using highly oxidizing microbiocides like chlorine dioxide.

Almost mineral scales can be inhibited by WS 8641 like Calcium Carbonate, Fe and Mn based scales, CaF₂ etc.

WS 8641 is suitable for use in waters containing high solids amounts.

WS 8641 has low Phosphorous content, making its use acceptable in environmentally sensitive areas.

Appearance : clear colourless to yellow

• Density (kg/m ³ ) : 1020 -1140

• pH : 2

• Freezing point : -5°C

These data are to be seen as typical values and should not be considered as specifications.

Continuous feeding at 5-25 ppm of WS 8641 is recommended for most applications. However, optimum dosage will depend on the nature and severity of fouling and the operational parameters of the system.

WS 8641 is an acidic material and therefore corrosion resistant feeding equipment should be used.

Wear suitable protective clothing, goggles and gloves. In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes.

For eyes, get medical attention. Remove and wash contaminated clothing.

If swallowed, drink large quantities of water. Do not induce vomiting and call a physician immediately.

Small spills may be flushed with water, larger spills should be soaked up with sand or other

absorbent material and swept up for safe disposal.

Store in a cool place, away from products containing sulphite or nitrite or strong alkalis.

Before use review the Material Safety Data Sheet for additional information.
