Description

WSM 90 SOLDER MASK – RED

WSM-90 solder mask is a red water-soluble polymer that cures at room temperature. It can be used with all kinds of fluxes. This material is formulated to resist the adhesion of solder to specified areas of the circuit board during the soldering operation.  After the solder operation, remove WSM-90 with hot water (140°F, 60°C) and it leaves no residue.

Application: Apply solder mask using a plastic squeeze bottle or by brush. Drying time varies according to mask thickness and relative humidity. Warm or cold dry air will quicken the drying time. Optimum coating thickness is 10 to 35 mils (.025 – 1 mm). For a thinner viscosity, water may be added up to 2% by weight.

Features:

  • Temporary Solder Mask
  • Non-Hazardous
  • Water-Soluble
  • Sold in 8oz Bottles
  • Has a shelf life of 12 months from date of manufacture.
  • can store at room temperature (72F, 22C) in an unopened container.
  • completely soluble in hot water, leaving no residue on the circuit board.
  • Warm or cold dry air will quicken the drying time.
