Pretreatment Filming Agent 

Product brief introduction:

It is prepared by the surfactant, organic phosphorus, corrosion inhibitor and other constituents, and during the pre-treatment of water, 预膜剂.png

it can pre-form a layer of composite metal film with special potential on the metal surface to balance the potential of system materials, 

effectively preventing electrochemical corrosion and corrosion under deposit. In addition, it can extend the service life of equipment. 

性能优点:
Performance advantages: 

1. Its main component is efficient harmless substances, and features short film forming time and friendly operation conditions. 

It can effectively remove the residual rust scale, and after pre-filming treatment and used cooperatively 

with the cooling water treatment agents, it has a better treatment effect. It can be used cooperatively with any water quality stabilizers. 

主要用途:
