Chemtronics Chemask® HV - High Viscosity Peelable CHV8 - Manual

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 wave solder in 4 minutes
 Dries tack free in 15 minutes

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 non-
critical area prior to use. Test compatibility
on bare copper.
