NC-102(HS211NC)Prefilming agent(equal to S-204)


    This product is the mixture of phosphate of zinc salt, which equals to the Japanese S-204. Its water solution can form an anti-scaling film on the surface of carbon steel in a short time, and can be compounded with the acrylic multipolymer.Or, after using this product for prefilming, you can add acrylic multipolymer and this product to act as scaling inhibitor and corrosion inhibitor. According to the many times of application by many factories in several years, the result is always satisfactory. This product is easy to absorb moisture and agglomerates, which may affect the solution speed.

(2) Use:

    It is suitable for prefilming of the oil pipes system or the carbon steel and stainless steel heat transformer in the cooling water circulation system. This product can also greatly enhance the anti-scaling effect upon used it for prefilming.

(3) Two Application Ways:
