Using UV LED technology to create a new era of efficient and environmentally friendly furniture coating

In modern manufacturing, efficiency and environmental protection have become core competitive advantages. Ultraviolet (UV) LED curing technology is an innovative solution that responds to this trend. It uses a specific wavelength of UV light to instantly excite a photoinitiator, triggering a molecular-level polymerization reaction in the resin, resulting in a strong, durable coating in a very short time. Traditional wood coatings require long drying and curing times. UV LED curing technology can quickly cure primers, topcoats, and UV glues, significantly improving production efficiency and creating a high-hardness, high-gloss surface.

The UV LED curing process for furniture typically involves several key steps:

1. Pre-treatment: Before painting, the wood or wood-based panel surface must be sanded, cleaned, and dusted. This step ensures that the coating adheres evenly and firmly to the substrate.
2. UV Primer Application: After pre-treatment, a UV primer is evenly applied to the furniture surface using a dedicated spray gun or roller coater. The UV primer fills the wood's pores and provides a smooth base for the subsequent topcoat.
3. UV Curing of Primer: After painting, the furniture immediately enters a UV curing machine. A UV LED lamp emits ultraviolet light of a specific wavelength, instantly activating the photoinitiator in the primer (usually within seconds), causing it to cure rapidly and form a hard film.
4. Intermediate Sanding: After the primer cures, the furniture surface becomes remarkably smooth. To ensure adhesion of the topcoat, the cured primer layer is lightly sanded and dust removed.
5. UV Topcoat Application: Next, a UV topcoat or a colored UV stain is applied, depending on the design. The topcoat imparts the furniture with its final color, gloss, and feel, while also providing protection against wear and scratches.

Key advantages of UV LED curing technology:

• Increased Production Efficiency: UV LED curing completes within seconds, significantly shortening production cycles and improving productivity. Rapid curing streamlines the coating process and reduces drying time.
• Environmental Protection: The process produces no mercury, ozone, or volatile organic compounds (VOCs), meeting environmental standards and improving the working environment.
• Energy Saving: UV LED light sources inherently consume little energy and eliminate the need for long, high-temperature baking, significantly reducing energy costs. Instant curing reduces paint waste.
• Enhanced Durability: The cured coating is hard, abrasion-resistant, and scratch-resistant, effectively protecting furniture surfaces.
• Superior Finish Quality: It also creates a smooth, even, and high-gloss finish.
