| PBTC 
			(2-Phosphonobutane 1, 2, 4-Tricarboxylic Acid) 
			We are the Importers, Exporters, Distributors and Supplier of PBTC 
			(2-Phosphonobutane 1, 2, 4-Tricarboxylic Acid). 
			PBTC chemical is high efficient agent for scale and corrosion 
			inhibitor. It is an excellent stabilizer for zinc salt. PBTC has low 
			content of phosphoric, has structural features of both phosphoric 
			acid and carboxylic acid group, which enable its excellent scale and 
			corrosion inhibition properties. PBTC is a highly effective 
			chelating agent and sequestering agent.

			ApplicationPBTC is usually used together with zinc salt, copolymer, 
			organophosphine, imidazole and other Water Treatment Chemicals.
 
			PBTC is widely used in circulating cool water system and oilfield 
			refill water system as scale and corrosion inhibitor 
			PBTC is used in situations of high temperature, high hardness, high 
			alkali and high concentration index 
			Multifunctional and cost effective performance makes it an excellent 
			replacement to other sequestrants e.g EDTA, DTPA, NTA
			etc
