The CW3300B is a blue, polymeric conformal coating pen designed to protect and insulate circuit board traces and other delicate electronics. This hard, durable coating provides excellent protection against shorts, moisture, and abrasion, with a high dielectric breakdown of over 500 volts/mil and a resistivity greater than 10^12 ohm-cm. It operates across a temperature range of -55°C to 125°C, becomes tack-free in under 5 minutes, and meets MIL-I-46058C and IPC-A-610D requirements. The pen is ideal for applications in circuit board manufacturing, repair, aerospace, and instrumentation where easy repair of solder mask and protection from environmental hazards is needed.
