Application:
PBTC controls scale where halogen-based biocides or hypochlorite bleach are employed. Controls calcium scale formation in high stressed alkaline conditions. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
PBTC is widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning. It is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
Package and Storage:
packed in 200L HDPE drum, 1000L IBC and ISO TANK.
Storage for 1 year in room shady and dry place.
We have the most advanced production equipment, experienced and qualified engineers and workers, recognized quality control systems and a friendly professional sales team pre/after-sales support for Manufacturing Companies for Water Treatment Chemical PBTC/PBTCA 50% CAS No 37971-36-1. We have confidence to locate our company to a pioneer management standard, more competitive and achieve a first-class grading. After years of hard work and development, we have grown a certain scale and strength.
