How to use

1. Requirement on pre-treatment

-Firstly, apply high-temperature degreasing, then wash with 1%~3% NaOH solution (60℃) for more than 6 minutes, dry it after water rinsing.

-Blast with 80#~120# corundum to make the surface roughness reach 2.0μ~3.0μ, pay attention to sandblast evenly;

-Wash with 1%~3% NaOH solution(60℃) for more than 6 minutes, rinse with water.

-Wash with 1%~3% hydrochloric acid solution (60℃) for more than 6 minutes, rinse with water and dry.

2. Preparation of the coating

-Dispersion of coating: the coating must be fully dispersed before operation. Rolling the coating at the speed of 300rpm with rolling machine for 10mins at least.

-Coating filtration: filtrate the coating with screen (100mesh) before using.

3. Application

-The spraying environment should be dry, well-ventilated, no smoking and fire. We suggest using dedicated spray gun, elevated tank and curing oven.

-The air compressor should be degreased, dewatered and equipped with water oil separator before using.

-Adjust atomization and oil pump capacity of the spraying gun; make sure the unit is clean and flat.

-Leveling the coating at 150~180℃ after spraying, cure it at 280℃×10min. Keep the dry film thickness at the range of 15μm~25μm.

-In spraying process, keep stirring inside of the elevated tank, the size of spraying nozzle should be between 0.8mm~ 1.3mm, the pressure is about 3.5bar.
