Coating Process of LC-FC130 Fluorinated Electronic Coating
Suitable for spray coating, dip coating, roll coating, and blade coating. For dip coating, control withdrawal speed to manage wet film thickness and uniformity. For spray coating, use fluoropolymer-compatible spray equipment; standard stainless steel or PTFE-lined equipment is recommended. Avoid metal equipment that may react with the fluorinated solvent carrier.
Applications of LC-FC130 Fluorinated Electronic Coating
1. PCBA and FPCA Protection
Applied to printed circuit board assemblies and flexible PCBs as a thin conformal barrier against condensation, dust, industrial oils, solvents, and corrosive gases (H₂S, SO₂, salt spray). Film thickness of 0.5–2.5 µm does not affect electrical connectivity of contact pads, test points, or connector pins — a functional advantage over conventional 25–125 µm conformal coatings where electrical contact must be maintained through the coating.
2. LED Surface Treatment
Applied to LED display surfaces and modules to deposit an anti-fouling, water-repellent, and oil-repellent film. Light transmittance ≥90% and colorless film maintain optical output and color rendering of the LED surface. Static water contact angle ≥110° prevents water adhesion and reduces dust accumulation on display surfaces.
3. Precision Anti-Migration (Epilame)
Applied to surfaces adjacent to lubricated components in micro-motors, high-end watch movements, and optical camera mechanisms to form a low-surface-energy barrier (10–12 mN/m) that prevents capillary migration of lubricating oils beyond the intended lubrication zone. LC-FC130-2 is the recommended grade for this application due to minimal film build and 30-second tack-free time compatible with precision assembly line throughput.
4. Hard Disk Drive (HDD) MR Head Protection
Applied to magnetoresistive (MR) read heads to prevent lubricant transfer from disk surfaces and particulate contamination. Film thickness control (0.5–1.5 µm for LC-FC130-2) is critical for MR head applications — verify film thickness by ellipsometry or profilometry before production qualification.
5. Precision Micro-Part Sealing
Used for environmental sealing of precision micro-parts, MEMS devices, and miniaturized sensors where conventional coating film thicknesses are incompatible with component dimensional tolerances.

Safety and Storage of LC-FC130 Fluorinated Electronic Coating
Keep in a cool, dry, and well-ventilated environment, strictly avoiding direct sunlight, heat, and ignition sources. The shelf life is 24 months from the date of manufacture when stored in original unopened containers. Classified as a non-hazardous substance for transport and handling. Storage beyond the shelf life does not necessarily mean the product is unusable; however, the properties required for the intended use must be thoroughly checked for quality assurance reasons prior to application.
