General

Remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating.

Surfaces must be clean and dry. Moisture, grease, sludge, dust, corrosive salt must be thoroughly cleaned from substrate.

Surface preparation standards can use SSPC-SP10 or Sa2 1/2 (ISO 8501-1:2007). Blast surface profile 1~3mils (25~75 microns) (Ref. ASTM D4417).

Mixing

Thinning

Mixing Ratio

Pot life

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

Above 25℃, use HT-type SP-13 thinner to thin up 3~5%. Below 25℃, use LT-type SP-13 thinner to thin up 3~5%

Base : Zinc dust = 23 : 77 ( by weight )

8 hours at 25℃ ( mixture, 77℉)

Spray Application

Airless

Spray

Brush

When the relative humidity is lower than 40%, water should be sprayed on after being painted for 30 minutes to promote hardening. The dry film thickness should not exceed 150 um to avoid cracking. This paint do not suitable for repairing or recoating, please use product No.1006 (EP-03AA) for repairing to avoid layer film cracking.

When overcoating, the air in the pores will escape through the next coating and may cause blister. A

mist coat then full coat can reduce this condition:

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

Caution : In difficult cases it may be necessary to thin the next coat.

Pump ratio 30:1 or greater

Tip size : 0.017’’~ 0.025’’

Output PSI : 2500~3800

For touch-up of areas less than one square foot only. Use medium bristle brush and avoid rebrushing.
