Chemask WF Solder Masking Agent CWF8 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.

FEATURES:

•  Protects boards from molten solder to 515°F (268°C)
•  Waste stream filterable with micron bags
•  Prolongs deionized water system life
•  Low foaming
•  Compatible with most flux types
•  Leaves no corrosive residue
•  Does not contain Methanol
•  Non-contaminating

TYPICAL APPLICATIONS: During wave soldering, Chemask WF Solder Masking Agent CWF8 protects:

•  Component Free Areas
•  Gold Connectors
•  Gold Fingers
•  Pin Connectors
