MIRAVEXL Clear Conformal Coating with Applicator Brush

Protect your electronic components with the MIRAVEXL Clear Conformal Coating — a professional-grade, fast-drying insulating varnish engineered for circuit boards, automotive electronics, aerospace assemblies, and household electronic devices. The complete kit includes an applicator brush for effortless, streak-free coverage right out of the bottle.

Key Features

  • High-Density Insulation Barrier: The cured conformal coating forms a robust electrical insulation layer that guards electronic components and extends their service life.
  • Waterproof & Moisture-Proof: Blocks moisture ingress and prevents the build-up of contaminants, helping to maintain stable circuit operation and reduce the risk of short circuits.
  • Wide Temperature Resistance: Withstands an operating range of -40°C to 130°C (-40°F to 266°F), making it suitable for demanding thermal environments.
  • Fast-Drying Formula: Smooth application with quick-drying performance saves time and effort. Full cure is achieved at room temperature within 24 hours.
  • Excellent Fluidity & Self-Levelling: Automatically fills micro-gaps for consistent, uniform adhesion without streaks, drips, or voids.
  • Broad Application Compatibility: Ideal for aerospace circuit boards, industrial electronics, automotive electromechanical boards, commercial and household circuit boards.
  • Easy 3-Step Application:
    1. Clean the surface to be coated.
    2. Apply the coating evenly using the included brush.
    3. Allow to cure at room temperature for 24 hours.
  • Complete Kit: Bottle with built-in applicator brush — everything you need included.

Frequently Asked Questions

Q: What surfaces is the MIRAVEXL conformal coating suitable for?

A: The MIRAVEXL clear conformal coating is designed primarily for electronic circuit boards and components, including aerospace, automotive, industrial, and household circuit boards. It bonds well to most PCB substrates, solder joints, and electronic components.

Q: How long does the conformal coating take to cure fully?

A: The coating is fast-drying and will cure completely at room temperature within 24 hours. Ensure the coated surface is left undisturbed in a well-ventilated area for best results.

Q: Can the MIRAVEXL coating handle extreme temperatures?

A: Yes. Once cured, the conformal coating withstands a temperature range of -40°C to 130°C (-40°F to 266°F), making it suitable for both very cold and high-heat environments without degrading its protective properties.

Q: Is the applicator brush included in the bottle?

A: Yes, the MIRAVEXL clear conformal coating bottle comes with a built-in applicator brush, giving you a complete, ready-to-use solution — no additional tools required.

Q: How do I prepare the surface before applying the conformal coating?

A: Before applying the coating, thoroughly clean the surface to remove dust, grease, flux residue, and any moisture. A clean surface ensures maximum adhesion and a uniform, streak-free protective layer.
