PRODUCT DESCRIPTION
Chemask
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
effect on deionized water (DI) system resin
beds. This water soluble formulation is
stable to rosin, organic and inorganic fluxes.
TYPICAL APPLICATIONS
During wave soldering, Chemask
Solder Masking Agent protects:
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
