UV CURE ETCH RESIST INK

SER 1406BK

 

SER 1406BK is a UV curable and alkali soluble etching resist ink, suitable for fine line screening with excellent reproducibility.

It has excellent resistances to acidic etching solutions such as ferric chloride, cupric chloride and is readily stripped in dilute caustic solution.

 

METHOD OF APPLICATION

1)     Stir thoroughly before printing for 5-10 minutes.

2)     Scrub boards with oscilation type scrubbing machine.

3) Printing
