Key Features
- Quick-Drying Formula: Dries rapidly (fully cures in approximately 24 hours) so you can get electronics back into service faster and minimise downtime during repairs or production runs.
- Crystal-Clear Protective Coating: Forms a fully transparent layer that preserves board visibility, keeps component markings legible, and allows easy inspection or servicing without removing the coating.
- Triple Environmental Resistance: Combines electrical insulation with waterproofing and moisture resistance, keeping circuit performance intact even in humid or demanding conditions.
- Crevice-Sealing Technology: Flows effortlessly into tight joints, gaps, and hard-to-reach areas for complete, uniform coverage on complex PCB layouts — enhancing durability wherever moisture may intrude.
- Fine-Tip Precision Applicator: The included fine-tip nozzle enables controlled, spill-free application on delicate components, making it ideal for small-batch repairs as well as larger production tasks.
- Versatile Use: Suitable for PCB boards, LED assemblies, circuit board terminals, sensors, connectors, and other sensitive electronics in workshop, home lab, or industrial settings.

Usage Notes
- Keep the bottle sealed when not in use. Take only as much as needed per session and reseal immediately after use.
- Some light surface crusting on the outer seal after extended storage is normal — simply remove it before use; it does not affect product quality.
- A small degree of thickening may occur during long-term storage. Thicker consistency extends cure time but does not impair performance.
- Slight colour variation may appear due to lighting and display settings; size measurements may have minor manual tolerances.

Frequently Asked Questions
Q: How long does the PCB board paint take to fully cure?
A: Surface drying is rapid, but for complete curing and maximum waterproof protection, allow approximately 24 hours. Thicker applications or cooler environments may extend this time slightly.
Q: Will this clear sealant obscure component markings on my PCB?
A: No. The coating dries to a completely transparent finish, so all component markings, silkscreen labels, and board traces remain fully visible for easy inspection and future servicing.
Q: Can this potting sealer be used on LED lights and other sensitive electronics?
A: Yes. The sealant is designed for use on a wide range of electronics including PCB boards, LED assemblies, terminals, sensors, and connectors, providing reliable insulation and moisture resistance without damaging sensitive components.
Q: How should I store the PCB board paint between uses?
A: Always reseal the bottle tightly immediately after each use. Store in a cool, dry place away from direct sunlight. Light surface crusting on the nozzle seal is normal after prolonged storage — remove it before use without concern.
