Circuit Board Protection Glue Description
"Reliable protection, easy inspection." This circuit board protection glue (3200) is an amber transparent, solvent-free UV curing conformal coating specially developed for EV battery pack BMS boards and flexible printed circuits (FPC). It offers low hardness, low irritation and low odor for a friendly working environment, good adhesion to PCB substrates, plastics, glass and metal, and its blue fluorescence makes coating inspection faster and easier. The cured film provides excellent anti-yellowing, moisture and chemical resistance.

Precautions
- Surfaces must be clean, dry and free of oil, dust or flux residues before coating.
- Apply a uniform coating thickness; avoid excess build-up around pads and connectors.
- UV curing requires light to reach the coating; shadowed areas under components may need additional passes.
- Apply in a well-ventilated area. Avoid contact with skin and eyes; wear protective gloves and safety goggles.
- In case of skin or eye contact, rinse immediately with plenty of clean water and seek medical advice if irritation persists.
- Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight, and keep out of reach of children.
- Coating performance may vary with substrate, thickness and UV intensity; please run a test before mass production.
FAQ
Q1: How does this circuit board protection glue cure?
It is a UV curing conformal coating that cures under UV light with a recommended cumulative energy of 1500 mJ/cm². Curing time depends on UV intensity, coating thickness and board layout.
Q2: What substrates can it protect?
It bonds well to PCB substrates, FPC, plastics, glass and metal, making it suitable for EV battery BMS boards and flexible printed circuits.
Q3: What is the blue fluorescence for?
The blue fluorescence allows fast and easy visual inspection of coating coverage, helping to confirm complete protection on the production line.
Q4: Is it low odor and safe for operators?
Yes. It is a solvent-free, low odor and low irritation formulation, providing a more comfortable and safer working environment compared with solvent-based coatings.
Q5: What is the packaging and minimum order quantity?
Standard packaging is 1kg / 5kg bottles, and the minimum order quantity is 10 pieces. Custom packaging is available on request.
Q6: How should it be stored and what is its shelf life?
Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight. Unopened shelf life is approximately 6 months.
