USAGE INSTRUCTIONS
For industrial use only.
Mix well before each use.
When applying by hand using squeeze
bottle, syringe or spatula, insure that all
areas of the pre-tinned hole are evenly
covered on the side to be soldered. For
screening applications, properly clean and
prepare screen, then apply masking agent in
the same manner as solder paste. Automatic
dispensing equipment may also be used as
appropriate. Allow an hour to fully cure a
10 mil thick application. Thicker
applications will require additional cure
time. Rapid cure can be achieved in a 120
o
F oven.
REMOVAL: After allowing the mask to
become fully cured, the mask may be
washed away in a open or closed loop
aqueous cleaning system with water
temperature at a minimum 120
o
F under
agitation. If using a recirculating system,
install a minimum 10 micron bag filter
before the resin beds.
Detergents may be used to increase cleaning
efficiency.
