Technical Data Sheet
PRODUCT DESCRIPTION
Chemask
Masking Agent is a fast curing, peelable
temporary spot mask formulated for safe use on
sensitive metals. It contains high-temperature
resistant compounds that protect component-free
areas during wave soldering. Chemask
may be used to protect pins, posts, contacts and
edge connections in the solder reflow oven or
during conformal coating processes.
TYPICAL APPLICATIONS
Chemask
Stable to 550°F (288°C)
For lead-free or tin/lead processes
Phthalate-free, low toxicity and
environmentally safe
Compatible with rosin, water soluble fluxes
and cleaning solvents
Dries tack free in 15 minutes
Goes straight into the pre-heat oven
Removes easily and leaves no residue
Non-contaminating, non-staining and non-
corrosive
Compatible with gold, copper, nickel, silver
and OSP finishes
RoHS compliant
Protects component-free areas during wave
and reflow soldering
Components and pin connectors
Temperature sensitive components during
wave or reflow soldering
The high temperature, peelable, temporary mask safe for use on sensitive metals
