Technical Data Sheet
Chemask HV Solder Masking Agent
PRODUCT DESCRIPTION
Chemask HV Solder Masking Agent is a
temporary, high viscosity, fast curing,
peelable solder masking agent. It is a high
temperature resistant compound that protects
component-free areas during wave soldering.
Chemask
HV can be introduced to the wave
solder preheat within 4 minutes without
adverse effects. Chemask
HV may be used
to protect pins, posts, contacts and edge
connections during conformal coating
processes.
Stable to 515°F (268°C)
Compatible with rosin, no clean, water
soluble fluxes and cleaning solvents
Leaves no residue
Ready for wa ve solder in 4 minutes
Dries tack free in 15 minutes
Non-contaminating
TYPICAL APPLICATIONS

COMPATIBILITY
Chemask
HV 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 noncritical area prior to use. Test compatibility
on bare copper.

USAGE INSTRUCTIONS
For industrial use only.
Read MSDS carefully prior to use.
Chemask
HV 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.
