Konform® Flexcoat

Flexible Conformal Coating

TDS # CTFC1

PRODUCT DESCRIPTION

Konform Flexc oat C onformal Coating is designed for applications where flexibility and protection are paramount. This material is as flexible as an RTV s ilicone, 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 hum idity, salt, corrosive vapors and fungus for printed circuit board and electronic assemblies. This coating can be rem oved by cutting a sm all section and peeling the coating away from the surface, or by solvent immersion of the w hole boar d. meets IPC-CC-830B Class B.

Coating

 Extremely flexible silicone free conformal

coating

 Clear, durable coating  Very good dielectric strength prevents arcing

and current leakage

 Increases life of electronic assemblies  Will not discolor over time under normal use  Contains a UV indicator for Qual ity Control

inspection using m edium intensity light a t 265-335 nm

TYPICAL APPLICATIONS

Konform Flexcoat Conformal Coating is ideal for applications in:

 Data Communications  Instrumentation  Automotive Manufacturing  Marine Manufacturing  Process Control

USAGE INSTRUCTIONS

For industrial use only. Read MSDS carefully prior to use. Before apply ing Konf orm clean cir cuit boards thor oughly to rem ove oil, gr ease, dirt, flux and all other ty pes of contamination. Allow to dry. Cleanin g m ay be p erformed with Chem tronics Electro-Wash



or Eco-Rite™ degreasing products.

SPRAY AP PLICATION: Appl y top to bottom, allowing coating to flow evenl y aro und com ponents. Rotate PCB 90 and repeat application. Rotate and apply coating two additional times, then allow board to cure. If additional thickness is desi red, apply additional coatings. When using liquid spray with automatic dispen sing equipment, adjustments may be requir ed in appl ication rate and viscosity.

DIP APP LICATION: Using auto matic equip ment or hand immersion technique, slowly immerse PCB into the coating and remove slow ly. Use an average rat e of approximately 1 foot per m inute. After allowing the board to cure, process may be repeated to achieve desired thickness.

BRUSH AP PLICATIONS: Evenl y appl y coating to areas desired at thickness required. Allow time for curing before reapp lying to achieve a thick coating. Use Chemask
