Suggested times of   coating

Airless spraying once,   dry coating thickness as 60~80 microns, brush painting or roller painting for   2~3 times.





Surface Treatment

Ø     Use sand blasting till the   level of Sa 2.5 to remove oxide skin and iron rust, roughness: 40~75 microns;

Ø     Be sure to get rid of the oil   stain and weld spatters on the steel plate before rust removal, and burnish   welding seams and closed angles;

Ø     For the surface coated with   shop primer, oil stain, moisture, zinc salts and dust must be removed. For   the partially rusty part, adopt local sand blasting till Sa2.5 Level for rust   removal, or adopt elastic grinding wheel buffing till St.3 Level.





Temperature of

base material

The temperature of base   material must be over 3(37.4) above the dew point.

When the temperature of   base material is below 5(41), the reaction of epoxy and solidifying agent becomes slow, which   is not suitable for using.





Usage

Mixing

The product is packed in   two containers separately that form a unit. For use every time, completely   and uniformly mix it according to the specified compounding ratio, and then   leave it stationary for slaking for 30 minutes. The product must be used up   within the specified mixture pot life.

Precautions

l           Overthickness of coating   should be avoided. Thick coating may result in the problem to the binding   power between the layers;

l           Overthick coating will   prolong the minimum interval of coating and handling time, and may have   adverse effect on the intervals of coating;

l           Long-time exposure of the   product to the atmospheric environment will cause atomizing and color fading,   though these phenomena will not influence the anticorrosive ability.
