PRODUCT DESCRIPTION
Chemask
and designed to be removed with most
aqueous cleaning systems. Chemask
contains high temperature compounds that
protect component-free areas from solder
during wave soldering. This water soluble
formulation is stable to rosin, organic and
inorganic fluxes.
TYPICAL APPLICATIONS
During wave soldering, Chemask
protects:
Protects boards from molten solder to
