 This anti etching ink offers a short time protection for all kinds of metal while doing etching(Protect the part does not need to be etched). It will be stripped after doing all the processing in the end.

Product Description                                                                                               

Craft Introduction:Metal etching is a surface treatment process, covering the metal substrate 

which part need to protect in printing or spraying then etching away the part we don't need with 

chemical corrosion.in order to improve the precision of etching,adapt to the demand of mass 

production,in order to solve this problem, our R&C department launched the sensitive antietching ink, and solving it by the photographic imaging and etching resistance performance of the ink. 

The ink is widely used in the etching process of metal products.

Characteristics:  Applying to spraying and screen printing, coating layer uniform and no bubbles, 

drying fast, high resolution, good adhesion, strong anti-acid performance, etc.

Technological Process: Clean the surface of the substrate-spray(screen printing)-prebaking-exposure-developing-second baking(for deep etching)-etching-removing the ink.

Operation Conditions:

1.Pretreatment:wash and remove the oil and wax on the surface of Product.

2.Dilution:Mix the ink and diluent together at suitable ratio,setting for 5-10mins, our specific diluent 

will be added to the ink to adjust the viscosity ( at 1:0.7 ratio, or operating according to the specific 

circumstances ) , the use of other thinners to be done before the production matching experiments;

3. Spraying:The thickness of dried ink film should be 20-30um. 

    Screen printing: Using 77T - 100T mesh size;

4.Prebaking:Hot air circulation drying at 80°C-90°C for 10-15mins;

5.Exposure:6-8 case,(21 case Exposure guide rule);

6.Developing:Washing with 0.8%-1.2% Na2CO3 solvent,about 2Kg / cm ² of the pressure , 

temperature at 30 ± 2°C;

7.Second baking: 150°C/30mins (if have deep etching process) ;

8.Etching;

9.Removing the ink:Remove the ink with 10% NaOH solvent at 90°c, then clean it with ultrasonic 

wave for about 1-3 minutes ;
