Black UV Light Curing Protective Coating for PCB

Solder Mask for Printed Circuit Board (PCB) is used to create a protective layer on the board. However, care must be taken not to apply it on connection paths or soldering points.

This Black UV Protective Coating for PCB, 100g, darkens the board when exposed to UV light by coating the PCB surface.

Using the solder mask protects the PCB from factors like oxidation and improves the board’s appearance.

Shake the solder mask well before use, and keep in mind that the UV Protective Coating for PCB is not dilutable.
