Technical Data Sheet
Konform® Flexcoat
Flexible Conformal Coating
PRODUCT DESCRIPTION
Konform Flexcoat Conformal Coating is
designed for applications where flexibility and
protection are paramount. This material is as
flexible as an RTV silicone, but without the
disadvantages of a silicone. Providing a soft,
rubbery protective coating, this material will
coat evenly and provide a flexible and durable
protective barrier against humidity, salt,
corrosive vapors and fungus for printed circuit
board and electronic assemblies. This coating
can be removed by cutting a small section and
peeling the coating away from the surface, or by
solvent immersion of the whole board.
meets IPC-CC-830B Class B.

USAGE INSTRUCTIONS
For industrial use only.
Read MSDS carefully prior to use.
Before applying Konform
clean circuit boards thoroughly to remove oil, grease,
dirt, flux and all other types of contamination. Allow to
dry. Cleaning may be performed with Chemtronics
Electro-Wash
SPRAY APPLICATION: Apply top to bottom,
allowing coating to flow evenly around components.
Rotate PCB 90° and r epeat application. Rotate and apply
coating two additional times, then allow board to cure. If
additional thickness is desired, apply additional coatings.
When using liquid spray with automatic dispensing
equipment, adjustments may be required in application
rate and viscosity.
DIP APPLICATION: Using automatic equipment or
hand immersion technique, slowly immerse PCB into the
coating and remove slowly. Use an average rate of
approximately 1 foot per minute. After allowing the
board to cure, process may be repeated to achieve desired
thickness.
BRUSH APPLICATIONS: Evenly apply coating to
areas desired at thickness required. Allow time for curing
before reapplying to achieve a thick coating. Use
Chemask
coating process.
CURING: Tack free time is 30 minutes at room
temperature. Accelerated curing can be obtained by
heating for 10 minutes @ 80
environments. Optimum cure cycles using radiant or
convection conveyer ovens are best determined
experimentally. Product may also be cured for 24 hours

accelerated cures as the product solvents are
flammable.
REMOVAL: After application, cured Konform
