UV-Curable Strippable Blue Masking Glue (UV Peelable Blue Gel)

UV curable peelable blue masking adhesive cures rapidly under UV light to form a flexible elastic protective film. Specially developed for temporary shielding of PCB solder points and precision electronic components. After curing, the film features high elongation and moderate adhesion, allowing complete peel-off without residue after processing.

• Fast UV Curing: Fully cured within seconds under 365/405nm UV LED light, no baking required, zero solvent volatilization, greatly boost production line throughput.
• Clean Full Peel-off, No Residue: Flexible cured film with high stretch rate; peels off completely without breaking or leaving blue residue, no damage to PCB, metal or plastic substrates.
• High Viscosity Anti-sag Formula: Thick paste texture, no dripping or sagging on vertical surfaces and tiny solder pads, ideal for precision micro masking.
• Multi-layer Barrier Protection: Dense cured film blocks moisture, water, flux, weak acid & alkali liquid, perfectly shield components during electroplating, washing and soldering processes.
• Low Odor & Mild Formula: Low irritation raw material formula, comfortable long-hour workshop operation without strong pungent smell.
• Wide Substrate Compatibility: Excellent adhesion on metal pads, PCB circuit boards, plastic earphone parts, glass, ceramics and sensor components.

• Store in black light-proof syringes / pails, keep away from natural sunlight and UV light to avoid premature curing.
• Recommended storage temperature: 10°C - 28°C, cool & dry warehouse, far from heat sources.
• Unopened original package shelf life: 12 months; finish using within 1 month once opened, seal tightly and shade from light.

• Contains acrylate photosensitive monomers. Wear safety goggles and nitrile gloves during operation to avoid direct skin & eye contact.
• In case of skin contact: wash thoroughly with running water and soap. If splashed into eyes, flush with large amounts of clean water and seek medical treatment immediately.
• Keep production workshop well ventilated, avoid long-term exposure to concentrated glue vapor.
• Non-edible, store out of reach of children.
• Fully cured film is non-irritating and non-volatile, safe for contact with electronic parts and human hands.
