Konform SR High Viscosity
TDS # CTSRHV
PRODUCT DESCRIPTION
Konform SR High Viscosity provides
maximum coverage where good flexibility is
required, or where extreme temperatures can
be encountered. This transparent coating
provides ideal protection for both rigid and
flexible printed circuit boards. Cured
coatings are hydrolyticly stable and retain
their physical electrical properties after high
temperature and humidity exposure.
Konform
SR High Viscosity will not stress
delicate circuit components.
Extends component life by protecting against
adverse environments
Good insulation properties, excellent
flexibility
Resists moisture, salt, fungus, corrosive
vapors, and severe environments
Engineered to withstand heat generated by
electronic circuitry as well as climatic
temperatures
Contains a UV indicator for thorough Quality
Control inspection
TYPICAL APPLICATIONS

Konform
SR High Viscosity 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
conformal coatings, clean circuit boards to
remove contamination and allow to dry.
Cleaning may be performed with Chemtronics
Electro-Wash
PX, Electro-Wash CZ, or high
purity acetone.
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
protect components during conformal coating
process.

REMOVAL: After application, cured
Konform
by soaking in Chemtronics
SR High Viscosity may be removed
Electro-Wash Two
Step, or an aromatic solvent (such as xylene), or
a short chain ketone (such as acetone).
