PRODUCT DESCRIPTION
Konform AR is ideal for providing
insulation against high-voltage arcing and
corona shorts. This extremely effective
acrylic conformal coating provides a hard,
durable protective barrier against humidity,
salt, corrosive vapors and fungus for printed
circuit board and electronic assemblies.
Konform AR resin meets MIL-I-46058C,
Type AR.
Clear transparent coating
Excellent dielectric strength
Helps prevent arcing and shorts
Increases life of electronic assemblies
Will not discolor over time under norm al
use
Contains a UV indicator for thorough
Quality Control inspection
UL Recognized, File E76307
TYPICAL APPLICATIONS
Konform AR is ideal for applications in:
Aerospace
Data Communications
Instrumentation
Automotive Manufacturing

COMPATIBILITY
Konform AR is generally compatible with
most materials found on printed circuit
boards. As with any chemical product,
product/component compatibility must be
determined on a non-critical area prior to
use.

USAGE INSTRUCTIONS
For industrial use only.
Read MSDS carefully prior to use.
Before applying Konform AR conformal coatings,
clean circuit boards to remove contamination and
allow to dry. Cleaning may be performed with
Chemtronics Flux-Off products.
SPRAY APPLICATION: Apply top to bottom,
allowing coating to flow evenly around components.
Rotate PCB 90° and repeat application. Rotate and
apply coating two additional tim es , 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 to protect components
during conformal coating process.
REMOVAL: After application, cured Konform
AR may be removed by soaking in Chemtronics
Electro-Wash Two Step.
