Clear Conformal Coating for PCB, LED & Electronics – 100ml/250ml
Clear Conformal Coating — Waterproof Protection for PCB, LED & Automotive Electronics
Keep your circuit boards, LED assemblies, and automotive electronics operating at their best with this fast-drying, crystal-clear conformal coating. Designed for hobbyists, technicians, and engineers alike, this transparent protective varnish forms a durable, moisture-blocking barrier that extends the service life of your electronic components — all while keeping every label and trace fully visible for effortless maintenance.
Key Features
- Crystal-Clear Transparency: Colorless and transparent formula maintains full PCB visibility — component labels, traces, and markings stay readable after application, streamlining inspection and servicing workflows.
- Reliable Environmental Protection: Forms a stable barrier against moisture ingress, oxidation, and dust accumulation, significantly reducing short-circuit risks in humid, dusty, or demanding operating environments.
- Fast-Drying Formula: Surface-dry in just 15–30 minutes; fully cured within 24 hours — minimising downtime whether you're completing a quick repair or a large-scale production run.
- Wide-Ranging Applications: Suitable for circuit boards, PCBs, LED setups, automotive electronics, motherboards, home appliances, and industrial control panels. Equally effective for pipe fixing and general electronic device repair.
- Lightweight & Portable: Compact bottle sizes (100 ml and 250 ml) are easy to store and carry — convenient for workshop benches, field repairs, and outdoor working environments.
- Strong Bonding & Sealing Performance: Fast-cure adhesive properties deliver dependable bonding during assembly and repair tasks, simplifying complex jobs with a single versatile solution.

Application Tips
- Ensure the surface is clean, dry, and free of grease or dust before applying.
- Apply a thin, even coat using a brush or spray method. For thorough protection, apply a second coat after the first has surface-dried.
- Allow 24 hours for full cure before exposing to moisture or mechanical stress.
- Work in a well-ventilated area and keep away from open flames during application.

Frequently Asked Questions
Q: What surfaces and components is this conformal coating suitable for?
A: This clear conformal coating is suitable for a wide variety of electronic surfaces including printed circuit boards (PCBs), LED assemblies, automotive electronics, motherboards, industrial control panels, and home appliance circuit components. It can also be used for pipe fixing and general electronic device repair.
Q: How long does the conformal coating take to dry and fully cure?
A: The surface becomes touch-dry within 15–30 minutes of application. Full cure is achieved after approximately 24 hours. Avoid exposing the coated surface to moisture or mechanical stress until fully cured for best results.
Q: Will the coating obscure component labels or PCB markings?
A: No. The formula is completely colorless and transparent, so all component labels, traces, and identification markings remain clearly visible after coating — making future maintenance and inspection straightforward.
Q: How many coats should I apply for optimal protection?
A: For standard protection, a single even coat is sufficient. For components exposed to particularly harsh or high-humidity environments, a second coat applied after the first has surface-dried (15–30 minutes) will provide enhanced moisture and oxidation resistance.
Q: Is this conformal coating available in different sizes?
A: Yes — this product is available in both a compact 100 ml bottle (approx. 110 g) and a larger 250 ml bottle (approx. 280 g), making it practical for small DIY repairs as well as larger professional or production-scale applications.
