Application Guidelines
1. Surface Preparation: The PCB surface must be thoroughly cleaned and fully dried. Ensure the removal of all flux residues, dust, grease, and other contaminants to achieve optimal coating adhesion and performance.
2. Preparation: Shake or agitate the container thoroughly before use to ensure the UV tracer is evenly distributed.
3. Application: When applying to PCBs, maintain the boards in a horizontal position during coating and the initial flash-off period to ensure a uniform, even film thickness.
4. Inspection & Rework: Inspect coverage using a standard UV light. If rework is required, use the designated Silfluo Conformal Coating Remover.
Safety & Handling Precautions
Safety: Once fully cured, the coating is completely safe and non-toxic. However, the uncured liquid contains solvents. Avoid direct skin contact and prolonged inhalation of vapors. If splashed into the eyes, flush immediately with copious amounts of clean water and seek medical attention. Always refer to the Material Safety Data Sheet (MSDS) before use.
Packaging & Storage
Packaging: Available in 1kg and 5kg containers. (Customized industrial packaging available upon request).
Storage: Store in a cool, dry, and well-ventilated environment. Strictly avoid direct sunlight and ignition sources. Maintain storage temperatures between 5°C and 28°C.
Shelf Life: 12 months in original, unopened packaging.
