Chemask WF – Water Filterable

Chemask® WF Solder Masking Agent is a high temperature temporary spot mask that protects component-free areas from molten solder during wave soldering. It is water soluble, designed to be removed with open and closed loop aqueous cleaning systems. Chemask® WF is low foaming and has no effect on deionized water (DI) system resin beds. This water soluble formulation is stable to rosin, organic and inorganic fluxes.
