Owner's manual
COMPATIBILITY
The CircuitWorks
Overcoat Pen material is
generally compatible with materials used in
printed circuit board fabrication. As with
any adhesive/sealant, compatibility with
substrate should be determined on a non-
critical area prior to use.
USAGE INSTRUCTIONS
Read MSDS carefully prior to use.
Cleaning: For best adhesion, clean the
board with a Chemtronics
Electro-Wash
cleaner in order to remove any surface
contamination which may prevent adequate
material contact.
Application: The overcoat material is
dispensed throughout the CircuitWorks
Overcoat Pen. Squeezing the pen body
while pressing down on the surface will
allow the material to flow.
Thinning: The overcoat material has been
optimized for the CircuitWorks
Overcoat
Pen and thinning is not normally necessary.
However, propyl acetate may be added with
thorough mixing to make slight adjustments
for ease of application in the bulk form.
Drying: The overcoat material dries in 5 to
10 minutes at room temperature. A heat
cure of 5 - 10 minutes at 200F (93C) is
recommended for more demanding
applications and for enhancing the chemical
resistance.
Clean-Up/Removal: The overcoat material
can be removed from surfaces using acetone.
