What is UV curing ink?

UV curing ink is a type of ink that uses a prepolymer system that can be polymerized by ultraviolet light (UV/LED) as the film-forming basis. It is quickly cured by UV light, forms a film instantly, and adheres to the surface of the substrate. It is specially optimized for printing fine graphics such as characters, numbers, batch numbers, logos, and warning signs.

UV Curing Ink Formula

Application Scenarios of UV Curing Ink

• Appliance nameplates, home appliance panels: Adhesion & chemical cleaning resistance.
• Metal/aluminum serial number: Scratch resistance
• Cable/pipe marking: Fast curing non-stick tape
• 3C electronic housing logo: High requirements for tinu characters
• PCB character ink (legend): High solder resistance requires special formula
• Label/package printing: High-speed printing with LED curing

UV Curing Ink Production Process

1. Premixing: Premix pigments, resins and additives at low temperature.
2. Wet grinding: Grind the pigment to a particle size of 5-15μm or finer.
3. Mixing and filtering: Mix the ground slurry withphotoinitiator, leveling agent, thixotropic agent, etc. in a vacuum stirring kettle.
4. Vacuum degassing: Remove bubbles to ensure the density and printing effect of the finished ink.
5. Quality inspection: Inspect fineness, viscosity, curing speed, adhesion, etc.
6. Filling and packaging: Use a semi-automatic/fully automatic filling machine for small cans or larger packaging.

Technical Feature of UV Curing Ink Production Line

1. Low-temperature production: Prevents premature reaction of UV resin and photoinitiator.

2. High-precision grinding: Particle size is controlled at 5-15μm to ensure sharp printing edges.

3. Vacuum stirring+defoaming: Avoid defects such as ink pinholes and bubbles.

4. Automation control: PLC+touch screen to achieve precise control of speed, temperature and time.

5. Environmental protection and energy saving: Fully enclosed production, extremely low VOC emissions.
