8. Sequestrants
• Forms chelates with Ca2+, Ba2+ and heavy metal ions
Fe2+, Fe3+
• Slows precipitation of low-solubility salts
• Prevents scale in boilers
Antiscale
• Works in sub-stoichiometric concentrations
• Stabilises of supersaturated solutions.
• Prevents non controlled precipitation.
VRAIWAN® SQ737 expands the
properties of complexing agents

9. Corrosion inhibitor
• Creates protection layers (not on Cu)
Dispersant/Deflocculant
• Disperses inorganic material
• Forms irregular crystal structures.
Stability to hydrolisis
• Even at high temperatures and extreme pH.
