APPLICATION METHOD

Airless Spray

NOTE

1. Pour the zinc dust gradually into the base with constant stirring, and then pass through 80 mesh of filter.

2. When used inside tanks, sufficient ventilation must be provided.

3. The air in the pores will escape through the next coating when overcoating and may cause blister. A mist coat then full coat can reduce this condition:

4. Spray a thin coat to fill the pores in the IZ-01R film, soon after apply to full specified film thickness to break the blisters.

5. Steel surfaces must be blast-cleaned to SIS Sa2 1/2, with moderate roughness (45 ~60 µ).

6. When the relative humidity is lower than 40%, water should be sprayed on after being painted for 30 minutes to promote hardening.

7. The DFT should not exceed 100 microns to avoid cracking.

8. Touch up and repair should be with EP-03 Epoxy Zinc Rich Primer.
