PRODUCT DESCRIPTION
Konform SR provides maximum flexibility
for extreme temperatures. This transparent
coating provides ideal protection for both
rigid and flexible printed circuit boards.
Cured coatings are hydrolytically stable and
retain their physical electrical properties
after high temperature and humidity
exposure. Konform SR will not stress
delicate circuit components. Konform SR
resin meets MIL-I-46058C , Type SR.
Extends component life by protecting
against adverse environments
Good insulation properties, excellent
flexibility
Resists moisture, salt, fungus, corrosive
vapors, a nd severe environments
Engineered to withstand heat generated
by electronic circuitry as well a s climatic
temperatures
Contains a UV indicator for Quality
Control inspection using medium
intensity light at 265-335 nm
UL Recognized, File E76307
Compliant to IPC-CC-830A
RoHS compliant
TYPICAL APPLICATIONS
Konform SR is ideal for applications in:
Aerospace
Data Communications

COMPATIBILITY
Konform SR 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 SR 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 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 to protect components
during conformal coating process. After application,
cured Konform SR may be removed by soaking in
Chemtronics Electro-Wash Two Step.
