WB3601 Water-base Peelable Solder Mask

WB3601 is a quick-drying, peelable, latex solder mask suitable for hand application. It withstands fluxing, wave soldering, and cleaning, effectively protecting open through-holes and underside components during wave soldering. It can also serve as a conformal coatings mask. The mask remains until testing and is easily removed. It’s ideal for situations requiring a thick mask layer and has been formulated to cure uniformly, removing any thickness limitation.

Features and benefits

  • Dries at room temperature, with heating reducing the drying time.
  • Can be completely peeled off by hand, leaving no residue.
  • Resistant to solvents and not broken down by shape coating.
  • Has a very high film strength and won’t break.
  • Suitable for point-coating and brush coating.


This mask is particularly suitable for soldering and coating operations. It excels in protecting shaped coatings such as male connectors, adjustable components, and IC slots. It has high film strength and won’t break or leave residue when hand-peeled.
