Features of LC-FC181 Fluorinated Electronic Coating
1. Highly Reworkable Design: Easily removed or soldered through, facilitating effortless circuit board repair, component replacement, and post-assembly modifications.
2. Dual Inspection Grades: Available in a standard clear finish (LC-FC181) and a specialized UV traceable grade (LC-FC183) for rapid, automated optical inspection (AOI) under ultraviolet light.
3. Ultra-thin, Nano-Scale Conformal Coating: Forms a highly reliable protective film without compromising electrical connectivity or thermal management.
4. Superior Repellency & Resistance: Delivers robust, long-lasting protection against water, moisture, damp-heat conditions, and rust/corrosion.
5. Rapid Room-Temperature Cure: Fast-drying formulation designed to optimize high-throughput manufacturing efficiency without thermal baking.
6. Outstanding EHS Profile: Non-flammable, non-hazardous, Zero ODP, and fully compliant with RoHS directives.
Coating Process of LC-FC181 Fluorinated Electronic Coating
Suitable for spray coating, dip coating, roll coating, and blade coating.
Applications of LC-FC181 Fluorinated Electronic Coating
1. PCBA & FPCA Shielding: Safeguards sensitive printed circuit boards and electronic components from aggressive condensation, dust, industrial oils, solvents, and corrosive gases.
2. Precision Anti-Migration (Epilame): Acts as a critical barrier to prevent the creeping and migration of lubricating oils in micro-motors and precision mechanical assemblies (e.g., high-end watches and optical cameras).
3. HDD Component Protection: Effectively shields Magnetoresistive (MR) heads in hard disk drives from lubricant transfer and particulate contamination.
4. Component Sealing: Ideal for the reliable environmental sealing and protection of precision micro-parts.
Packing of LC-FC181 Fluorinated Electronic Coating
In 100g, 500g, 1kg, 25kg.
Safety and Storage of LC-FC181 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.
