Phosphino carboxylic acid copolymer (PCAC)

​Connect Chemicals is well recognized in the market as expert and capable partner for water treatment additives. Thanks to Connect Chemicals engineer experience we've developed a polymers series for water treatment including our Phosphino carboxylic acid Copolymer (PCAC).

Phosphino carboxylic acid copolymer is a multifunctional deposit control agent that provides great flexibility in developing phosphonate-based corrosion control formulations for cooling water, process water, and similar applications.

The use of PCAC in the formulation can provide:

  • Phosphate inhibition/dispersancy and calcium phosphonate stabilization
  • Iron oxide dispersancy
  • Zinc stabilization
  • Calcium Carbonate

PCAC can be used in the formulation as a building block to improve the performance of phosphate, polyphosphate, phosphonate, and zinc-based products.

Phosphino carboxylic acid copolymer (PCAC) is soluble/miscible in Water and Ethylene glycol in all proportion.
The product is soluble in Caustic Soda (50%). If diluted with Methanol may create a turbid solution.

Phosphino carboxylic acid Copolymer (PCAC) is stable at temperatures up to 300°C.

Oxidizing agent:
Phosphino carboxylic acid Copolymer (PCAC) is not affected by chlorine or other oxidizing biocides in standard conditions.

PCAC is FDA approved under 21 CFR 176.170 - 176.180
