Characteristics and Advantages of UV Adhesive Curing by LEDUV Curing Lamps

- UV Adhesives Bond Transparent Materials Tracelessly with Excellent Optical Properties
Many industrial products are made of transparent materials, such as glass, crystal products and art crafts. If opaque adhesives are used for bonding such transparent products, the aesthetic appearance of the products will be compromised. UV adhesive is a colorless and transparent liquid with a light transmittance > 90% after curing, and is also known as shadowless adhesive. The adhesive remains transparent after curing, with no traces visible to the naked eye, ensuring an excellent aesthetic finish of the bonded products.
- Diverse Bondable Materials, High Bonding Strength after Curing, and Wide Application
The bonding strength of UV adhesive after curing is comparable to that of the base materials themselves. The bonded joint is not easy to crack even if the product is dropped on the ground. UV adhesive is non-corrosive to various inks, and can withstand extreme low and high temperatures with a temperature resistance range of -60℃ to +130℃. It also features excellent waterproof, anti-aging and weather resistance properties, and will not yellow over time. It is widely used in industries such as microelectronics, optics, optical communication, medical care, automotive, aerospace, and the currently booming virtual reality (VR) industry.
- Safe, Eco-friendly, Fast Curing and Controllable Reaction
Nowadays, many adhesives are solvent-based and release certain toxic gases both before and after curing. In contrast, UV adhesive is recognized worldwide as a safe and eco-friendly adhesive product, with no harmful substances released at any stage before or after curing. It has an ultra-fast curing speed – curing can be completed in a few to tens of seconds – which facilitates the operation of automated production lines and effectively improves labor productivity.
- Simple and Convenient Bonding Process, Suitable for Automated Operations
The curing of UV adhesive is achieved under the irradiation of LED UV curing lamps. Without UV irradiation, the adhesive will not cure, making it easy to clean excess adhesive or adjust the bonding position of workpieces. Glue application can also be completed by a 3-axis dispensing machine, which is simple, convenient and efficient. UV adhesive achieves initial curing in 1-5 seconds and complete bonding in 20-30 seconds under LED UV irradiation, and can reach high bonding strength immediately after curing, which perfectly meets the rhythm requirements of automated production lines.
