• Usage Instructions:
  • Fully stir the solder mask. Do not dilute.
  • Apply UV curable solder mask on your PCB in drops
  • Place a thin plastic sheet on top of the PCB and solder mask drops you've applied and use a thick card to spread solder mask into a uniformly thin layer
  • Expose it under UV light ( or direct sunlight ) for a few minutes (depends on what type of UV curing oven or UV light source you use)
  • You can wash away any excess solder mask with gasoline-based-solvent or oil-based-solvent
