DESCRIPTION
VRAIWAN SQ737 is a novel ingredient for detergent, cosmetics, lubricant and paint industries. It acts as a complexant and dispersant with no acute ecotoxicity and fully biodegradable. By its design, it can also act as a 1:1 replacement of NTA, thus letting you minimize your R&D costs.

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
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.
