TH-628 Scale and Corrosion Inhibitor
Properties:
TH-628 is composed of organophosphine acid, polycarboxylic acid, sulfosalt copolymers and thiazole. It can chelate and disperse calcium carbonate and calcium phosphate scales. TH-628 has good scale inhibition effect on steel & iron and copper. TH-628 can be operated under high concentration index in power plant, chemical plant and central air conditioner.
