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 30rpm with rolling machine for 30mins, shouldn’t exceed 60 mins.

-Viscosity adjustment: the viscosity could be adjusted according to different spray methods. Dilute with clean water if the viscosity is over high.

-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.

-Preheat the substrate to 35℃ and spray the primer. Dry it at temperature of 120℃~180℃ for 10min-15min. Keep the thickness of primer within 15μm-20μm.

-Spray top coating after the primer is dry and cooling to room temperature,then spray the dot(as the rules of : darker dots first, then lighter dots). Dry the unit at the temperature of 150℃~200℃ for 10min~20min, and gradually increase the temperature to 400℃~410℃(the temperature of substrates), keep for 10 min~15 min. Keep the thickness of top coat within 8μm ~12μm,total thickness of two dots is 12μ-18μ. The total thickness of final coating film should be between 35μm~45μm.

-In spraying process, keep stirring inside of the elevated tank, the size of spraying nozzle should be between 1.3mm ~ 1.5mm, the pressure is about 2.5-4 bar.

-The oven (or the tunnel drier) must be well ventilated; otherwise, it will lead to color changing of coating.
