UV glue, also known as UV-curable adhesive or UV resin, is a type of adhesive that cures and hardens when exposed to ultraviolet (UV) light. It is commonly used in various applications such as bonding, sealing, and coating.

Here are some key points about UV glue:

Activation: UV glue remains in a liquid or gel-like state until it is exposed to UV light. Once exposed, the UV light triggers a chemical reaction known as photopolymerization, causing the glue to harden or cure rapidly.


Transparency: UV glue is typically transparent or translucent, allowing light to pass through it. This characteristic makes it suitable for applications where transparency is desired, such as glass bonding or optical devices.


Bonding strength: UV glue can provide strong bonds when used appropriately. However, its bonding strength may vary depending on the specific formulation and the materials being bonded. It is important to choose a UV glue that is compatible with the materials you are working with and follow the manufacturer's guidelines for optimal results.


Applications: UV glue is widely used in electronics manufacturing, optical industries, jewelry making, and crafts. It can be used for bonding glass, plastic, metal, ceramics, and various other materials. UV glue is also popular for repairing phone screens, bonding small components, or sealing delicate electronics.


UV light source: To cure UV glue, you need a UV light source. This can be a specialized UV lamp or a UV LED flashlight designed for curing UV adhesives. It is crucial to use the appropriate wavelength and intensity of UV light recommended by the UV glue manufacturer to ensure proper curing.


Safety precautions: When working with UV glue, it is important to protect your eyes and skin from direct exposure to UV light. Wear safety goggles that block UV radiation and avoid prolonged contact with uncured glue. Follow the safety guidelines provided by the manufacturer.

Remember to read and follow the instructions provided by the specific UV glue product you are using, as the application and curing process may vary.
