Overcoat Pen

Product# CW3300C, CW3300G, CW3300BLACK,

CW3300WHITE

Product Description

CircuitWorks Overcoat Pen is ideal for protecting and insulating

circuit board traces, components, and other delicate

electronics. This highly effective acrylic conformal coating

provides excellent protection against shorts, moisture,

abrasion, fungus, and other environmental hazards. Allows for

easy repair of solder mask in prototype, manufacture and

repair of circuit boards.

• Simple to use, single component system

• Hard, durable coating

• High dielectric strength

• Helps prevent arcing and shorts

• Contains fluorescent indicator

• Protects against moisture damage

• Meets requirements of MIL-I-46058C

• and IPC-A-610F

• Helps prevent static discharge problems on sensitive

components

Typical Applications

CircuitWorks Overcoat Pen may be used for electronics

applications in:

• Circuit Board Manufacturing

• Data Communications

• Aerospace

• Instrumentation

• Controls

• General Maintenance and Repair

Chemical Resistance

CircuitWorks Overcoat Pen has excellent resistance to water-

based cleaners and limited resistance to aggressive organic

solvents such as acetone. The chemical resistance of CW3300

can be enhanced by heat curing.
