Chemask ® LF Lead-Free
Solder Masking Agent
Product# CLF8
Product Description
Chemask LF Lead-Free Solder Masking Agent is a temporary,
fast curing, peelable solder masking agent formulated for use in
high temperature lead-free applications. It is a temperature
resistant coating that protects component-free areas of the PCB
during wave soldering. Chemask Lead-Free can be introduced
into the preheat oven within 4 minutes of application without
adverse effects. Use to protect pins, posts, contacts and edge
connections during conformal coating processes.
• Stable to 550°F (288°C)
• Can be used in lead-free or Tin/Lead applications
• Compatible with rosin, no clean, and water soluble fluxes
• Unaffected by cleaning solvents
• Leaves no residue – non-contaminating
• Ready for wave solder in 4 minutes
• Dries tack free in 15 minutes
• RoHS compliant
Typical Applications
Chemask LF Lead-Free Solder Masking Agent protects:
• ComponentfFree areas for soldering
• Components and sockets
• Pin connectors during soldering
• Temperature sensitive
components during
wave soldering

Product# CLF8
Compatibility
Chemask LF Lead-Free 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. Test compatibility on bare copper.
Application Method
Squeeze Bottle/Syringe
Yes
Spatula
Yes
Screening
No
Automatic Dispensing
Yes
Removal/Clean-up
By Hand
Usage Instructions
For industrial use only. Read SDS carefully prior to use.
Chemask LF Lead-Free Solder Masking Agent is engineered
for all electronic manufacturing applications. When applying by
hand using squeeze bottle, syringe or spatula, insure that all
areas of the pretinned hole are evenly covered on the side to
be soldered. Automatic dispensing equipment may also be
used as appropriate.
REMOVAL: After allowing the mask to become fully cured,
peelable solder mask can be removed by hand or by the use of
tweezers. Depending on ambient conditions, peelable mask
may remain on assemblies for extended periods of time prior to
component insertion.
