Our products are available to hand spraying, mechanical arm ABB line operating, automatic coating line with fixed spraying gun, and etc. SK-S3100 and SK-S3200 are plastic base coatings; SK-S3010, SK-S3020, SK-S3030 belong to the UV-curable top coatings; SK-S3100 is a high-performance plastic base coating and can be operated separately but better effect can be achieved if UV-curable top coatings added. SK-S3010 is a kind of high abrasion resistant top coating with excellent RCA abrasion resistance.
Operating processes:
      The pretreatment of parts to be coated→operating electrostatic precipitation→adjusting coatings→spraying plastic base coating→60℃-70℃* 10-15 minutes→spraying the UV-curable coating→55℃* 5-8 minutes→UV curing→packing

A）：Notes for workers in spraying process
(1) Please read the Material Safety Data Sheet (MSDS) carefully before operating;
(2) Please wear the protective clothes and gloves, protective facial mask and protective glasses during the operation;
(3) Please clean your hands timely after finished the operation.
B）Preparation work before operation
(1) For better effect, please use IPA, absolute alcohol or heptane to clean the surface of parts to be coated;
(2) Please stir the coating completely, barrel or stirring mill may be used;
(3) We offer the operating flow chart based on your special projects, please dilute the coating referring to the chart;
(4)Adjust the mass ratio of matting paste to the lacquer to achieve various gloss;
(5) For better surface effect, please filter screen in 500# (4 layers) to filter the coatings according to the operating flow chart;

C）Spraying method
（1）Feed the filtered coating into the container and then spray coating with unceasing stirring at the speed of 80-100 r/m;
(2) The air pressure for spraying plastic base coatings is about 0.4-0.5Mpa, and about 0.3-0.4Mpa for UV-curable top coatings; adjust the distance between the spraying gun and the parts to be coated and make the fogging width and fogging conditions proper.
（3）According to spraying surroundings, feed proper diluent into coatings to achieve excellent surface effects and properties.

D） Drying conditions
 (1) Plastic base coating should be dried for 10-15 minutes at 60-70℃ by IR heating before spraying the top coating;
(2)UV-curable top coating should be dried for 5-8 minutes at 55-65℃ by IR heating before entering UV furnace;
(3) The exposure energy for UV curing：800-1200mj/ cm2.

E) Quality control
(1) The thickness of dry base coat film: 8-15µm
The thickness of dry top coat film:  8-12µm
(2) Ensure 10 minutes baking at 70℃ after UV curing, and then check the color.
