Frequently Asked Questions
What is the copolymer of phosphono and carboxylic acid (PCA) used for?
PCA (phosphino-polycarboxylic acid copolymer, CAS 71050-62-9) is a phosphorus-backbone polycarboxylate used as a combined scale and corrosion inhibitor in industrial water-treatment programs. It controls calcium carbonate, sulfate, and phosphate scale and provides mild-steel corrosion inhibition in cooling systems.
Why is PCA used at high water hardness and cycles of concentration?
PCA is valued for its calcium tolerance and deposit control, allowing programs to run at higher hardness and cycles of concentration without dropping out. The phosphino backbone combines threshold scale inhibition with corrosion control in one product.
What form is PCA copolymer supplied in?
It is supplied as an aqueous solution. Request a CoA and SDS with your quote to confirm active solids, molecular weight, and specification for your treatment program.
What packaging is bulk PCA copolymer available in?
It ships as a liquid in drums, IBC totes, and bulk. Submit your target volume and required active solids with your RFQ for a current quote.
What is the CAS number for PCA copolymer?
The referenced CAS number is 71050-62-9 for the phosphino-polycarboxylic acid copolymer. Confirm identity and active content against the CoA before formulating.
