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 partially rusty part,   adopt local sand blasting till Sa2.5 Level for rust removal.





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.
