Frequently Asked Questions
Q: What surfaces is this conformal coating compatible with?
A: This clear conformal coating is formulated for use on plastic-based electronics including PCB circuit boards, motherboards, LED assemblies, and automotive electronic components. It bonds well to most smooth electronic surfaces and is suitable for both commercial and industrial repair applications.
Q: How long does the conformal coating take to fully cure?
A: The surface becomes touch-dry within 15–30 minutes of application. Full curing is achieved within 24 hours under normal room temperature conditions. Avoid exposing the coated board to moisture or stress during the curing period for the best results.
Q: Will the coating obscure markings or labels on my circuit board?
A: No. The coating dries completely colorless and transparent, so all PCB labels, silkscreen markings, and component identifiers remain fully legible after application — making maintenance and troubleshooting as straightforward as ever.
Q: What size should I choose — 100 ml or 250 ml?
A: The 100 ml bottle is ideal for occasional repairs, small PCB projects, or portable field use. The 250 ml bottle is better suited for larger-scale industrial, automotive, or workshop applications where more coverage is needed.
