LEDUV lamp 365nm to curing the adhesive and coating on PMMA and metal

The key advantages of using UVLED lamps for curing acrylic (PMMA) lie in their single-wavelength characteristics, low heat radiation, and rapid curing capability, which can effectively improve production efficiency and product quality.

Curing Principle
UVLED lamps emit single-wavelength ultraviolet light (e.g., 365nm, 395nm) from a semiconductor chip, precisely matching the absorption peak of the photoinitiator, thus initiating the polymerization reaction of the acrylic coating on the surface and achieving rapid curing within seconds. Compared to traditional mercury lamps, it offers more than 40% higher energy efficiency and avoids infrared radiation damage to the acrylic substrate.

Key Advantages:
Energy-efficient: Consumes only 1/3 the power of traditional mercury lamps, and is ready for immediate use without any preheating;
Environmentally friendly and safe: Free of mercury pollution, compliant with RoHS directives, and meets green production standards;
Long lifespan and low maintenance: LED light source has a lifespan of over 20,000 hours, reducing maintenance costs to 1/10th of traditional equipment;
Precise control: High light uniformity ensures even curing, eliminating dead spots and guaranteeing a smooth, flawless surface on acrylic products.
