NC-403(ZH341NC)Anti-scaling corrosion inhibitors(W331-B)

(1) Property:

This product, which is composed by Organic phosphor, zinc salt and sulfosalt polymer and Cu corrosion inhibitors, is a totally organic alkaline water treatment agent without heavy metal and polyphosphates. It is suitable for all kinds of water quality range, with no need to adjust pH value. It is easy to use and convenient to manage, and with lower toxicity. It has excellent anti-scaling property to calcium carbonate and calcium phosphate. Especially in the low-hardness and lower-concentration water, this product can effectively reduce the corrosion rate.

(2)Use:

NC-403 Anti-scaling and corrosion inhibitor, can be used as anti-scaling and corrosion inhibitor in the open circulation cooling water systems as well as all kinds of heat-exchanging equipment, and can also be used in high-hardness, high-alkalinity, high-pH circulation water systems.
