Application Instruction
Surface preparation
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 Pour
the zinc dust gradually into the base with constant stirring and then pass
through 80 mesh filter.
Thinning Above 25 use HT-type SP-13 thinner to thin up 3~5%. Below 20
, use LT-type
SP-13 thinner to
thin
up 3~5%
Mixing Ratio Base : Zinc dust = 23 : 77 ( by weight )
Pot life 8
hours at 25 ( mixture, 77
)

Spray Application
|
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 is not suitable for repairing or recoating, If
the coating system used at room temp environments (lower than 250
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. Not recommended |
), please
use product No.1006 (EP-03AA) for repairing. If the coating system used at
high temp environments (over 250
), please
use product No.1566 for repairing.

Cleanup
Safety Ventilation |
Use No.1012 Inorganic Zinc Rich Thinner (SP-13) to clean. In case of spillage, absorb and dispose of in accordance with local applicable regulations. Please read and follow all caution statements on this product data sheet and MSDS for this product. Proper ventilation and protective measures must be provided during application and drying to keep solvent vapor concentrations within safe limits and to protect against toxic or oxygen deficient hazards. |
