Applications of LC-FC631/633 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-FC631/633 Fluorinated Electronic Coating
In 100g, 500g, 1kg, 25kg.
Safety and Storage of LC-FC631/633 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.
