PCB Conformal Coating 100ml – Clear Waterproof Circuit Sealant
PCB Conformal Coating 100ml – Clear Waterproof Circuit Sealant
100ml Transparent PCB Conformal Coating with Brush Applicator
Keep your electronics running strong with this fast-drying, clear conformal coating designed for PCB boards, circuit assemblies, LED terminals, and electrical splices. This 100ml protective sealant creates a tough, transparent barrier that locks out moisture, humidity, and environmental contaminants — all while preserving full component visibility for easy inspection and servicing.
Key Features
- Quick-Dry Formula: Achieves surface dryness rapidly, minimising downtime during urgent repairs and keeping your workflow moving on time-sensitive projects.
- Triple-Layer Protection: Provides electrical insulation, moisture resistance, and waterproofing in a single coat — ideal for protecting sensitive electronics in damp or high-humidity environments.
- Crystal-Clear Finish: The transparent coating preserves all component markings and labelling, supporting hassle-free inspection, diagnostics, and servicing without removing the coating.
- Flows Into Tight Spaces: The low-viscosity formula seeps into narrow crevices and conforms to complex board layouts, ensuring complete, even coverage on intricate PCB configurations.
- Fine-Tip Brush Included: The precision brush applicator makes manual application straightforward, reduces spillage risk, and delivers consistent, controlled coverage — perfect for small-batch or spot-repair applications.
- Wide Compatibility: Suitable for PCB boards, LED lights, electric terminals, circuit splices, and other sensitive electronic components across appliances, industrial equipment, and DIY electronics.

Usage Tips
Apply a thin, even coat over the circuit board using the included brush. Allow to cure fully — standard curing typically takes up to 24 hours depending on coat thickness and ambient conditions. Keep the bottle tightly sealed between uses to prevent premature curing. If a small crust forms on the inner seal after extended storage, simply remove it — it does not affect the product inside.

Frequently Asked Questions
Q: How long does the PCB conformal coating take to fully cure?
A: The coating typically reaches surface dryness quickly, but full curing usually takes up to 24 hours. Thicker coats may require additional curing time. Ensure the coated board is left undisturbed in a well-ventilated area for best results.
Q: Can this circuit board sealant be used on LED lights and electrical terminals?
A: Yes. This conformal coating is compatible with PCB boards, LED lights, electric terminals, circuit splices, and a wide range of other electronic components. Its low-viscosity formula flows into tight spaces, ensuring thorough coverage across complex layouts.
Q: How should I store the PCB coating between uses?
A: Always reseal the bottle tightly immediately after each use. Take out only the amount you need for each application session. If a small crust develops on the inner seal after long-term storage, remove it carefully — the product inside remains usable and unaffected.
