Technical data sheet, Chemask, Aqua

PRODUCT DESCRIPTION
Chemask
Aqua 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
Aqua 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.
Protects boards from molten solder to

COMPATIBILITY
Chemask
Aqua Solder Masking Agent is
generally compatible with most materials
used in printed circuit board fabrication. As
with
any
solder
masking
agent,
compatibility with substrate must be
determined on a non-critical area prior to
use.
