Konform® HR

Water-Based Hybrid Acrylic/Urethane Conformal Coating

PRODUCT DESCRIPTION

Konform HR H ybrid C onformal Coati ng is a
unique protective coating offering the insulating
dielectric advantages of an acrylic coating with
the chemical resistan ce of a urethane system.
Formulated with a unique acrylic / urethane
backbone, this resin system offers effective
circuit board protection with a water based
carrier. K onform
protective barrier agai nst humidity, salt,
corrosive vapors and fungu s for printed circuit
board and electronic asse mblies. Coating meets
IPC-CC-830B Class.

USAGE INSTRUCTIONS

For industrial use only.
Read MSDS carefully prior to use.
Before applying Konform® HR Hybrid

Conformal Coating

thoroughly to rem ove oi l, grease, dirt, flux and all
other types of contam ination. Allow to dry.
Cleaning m ay be perform ed with Chem tronics
Electro-Wash or Eco-Rite™ degreasing products.
Do not apply to iron or untreated steel.

DIP APPLI CATION: Using auto matic equipment
or hand imm ersion technique, slowly immerse PCB
into the coating and rem ove slowly. Use an average
rate of approxim ately 1 foot per m inute. After
allowing the board to cure, process m ay be repeated
to achieve desired thickness.

BRUSH APPLICATI ONS: Eve nly apply c oating
to are as des ired a t th ickness requ ired. Allow tim e
for curing before reap plying to achieve a thick
coating. Use Chem ask
during conformal coating process.

CURING: For the best coating appearan ce and
adhesion, cure in conditions with good air flow and a
relative humidity below 70% . Accelerated cure may
be accom plished by lo wering am bient hum idity, or
elevating temperature up to 170°F (77°C).
