Product Description

CAS NO. 6419-19-8

Molecular Formula:N(CH2PO3H2)3

Molecular Weight: 299.05

Product Advantage:                                                                                                        

ATMPA has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. ATMPA has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.

Product use:                                                                                                         

1. ATMPA is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.
2. The solid state of ATMPA is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.

Method of use:
ATMPA is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all organic alkaline water treatment agent. ATMPA can be used in many different circulating cool water system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.

Packing and storage:
