Enhancing efficiency, finish quality, and sustainability with UV curing for wood coatings

Ultraviolet (UV) curing for wood coatings provides an effective and efficient alternative to traditional air, moisture, and thermal cured coatings. UV curing provides faster curing times, reduced energy consumption, and improved coating performance. Additionally, the process emits fewer volatile organic compounds (VOCs) to support compliance with ISO 14001 and reduces the emission of hazardous air pollutants (HAPs), making it a more sustainable and environmentally friendly option for wood coatings.

Excelitas offers a wide range of UV curing solutions to support the wood manufacturing industry. Our wide format Phoseon VeriCure UV LED curing system was designed specifically for the wood coating market. The VeriCure offers some of the most advanced and reliable UV LED curing solutions on the market, enabling manufacturers to produce high-quality products, with more durable and long-lasting coatings.

Understanding UV Curing in Wood Coating Applications

UV curing involves exposing a specially formulated resin to high-intensity UV light. This process initiates a photochemical reaction that causes the coating to harden and become cured, creating a durable scratch-resistant finish on wood surfaces.

The main types of UV curing light sources used in wood coating applications are mercury vapor lamps, microwave UV systems, and LED systems. Mercury vapor lamps and microwave UV have traditionally been used and are well-established in the industry, while LED technology is newer and rapidly gaining popularity due to higher energy efficiency and longer lamp lifetime.

UV curing is widely used to support wood coating, excimer gelling, parquet oils and coatings, and inkjet inks for wood decoration. Many UV-curable fillers, stains, sealers, primers, and topcoats (pigmented, clear, varnishes, lacquers) are used in the manufacture of a broad range of wood-based products, including furniture, pre-finished flooring, cabinets, doors, panels, and MDF.

UV Curing for Furniture

UV curing is often used to cure coatings on wood-based materials used in the manufacturing of furniture such as chairs, tables, shelving, and cabinets. It provides a durable, scratch-resistant finish that can withstand wear and tear.

UV Curing for Flooring

UV curing is used to cure coatings on hardwood floors, engineered wood floors, and luxury vinyl tile. UV curing creates a hard, durable finish and can enhance the natural beauty of wood and vinyl flooring.

UV Curing for Cabinets

UV curing is used to cure coatings on wood-based materials used in the manufacture of wood cabinets for kitchens, bathroom vanities and custom furniture pieces, producing a hard, scratch-resistant finish that can withstand daily wear and tear.

UV Curing for Wood-Based Substrates

UV curing is a popular technology for wood-based substrates such as kitchen cabinets, office furniture, wood flooring, and wall paneling. Some common wood-based substrates are medium density fiberboard (MDF), plywood, particleboard, and solid wood.

Advantages of UV curing include:

High Efficiency and Fast Production Rates

• Faster curing times
• Elimination of lengthy drying times
• Precise control to reduce waste
• Elimination of lamp warmup times
• Ideal for temperature-sensitive applications

Reduced Environmental Impact

• Reduction or elimination of VOCs
• Reduced energy consumption and costs

High Quality Finish

• Improved scratch and wear resistance
• Improved durability
• Improved adhesion and chemical resistance

Advancements in UV Curing Technology for Wood Coating Applications

Newer UV curing technologies offer faster curing times, lower energy consumption, and reduced operating costs, making UV curing an increasingly popular choice in the wood coating industry.

One of the most significant advancements has been the development of UV LED curing technology, which has proven more energy-efficient, provides longer-lamp lifetime, and is more environmentally friendly than traditional UV lamps. Additionally, new types of UV-curable resins and coatings have been developed, which offer superior hardness, scratch resistance, and chemical resistance.

With ongoing advancements in UV curing technology, many wood coating manufacturers are exploring the benefits of UV curing and implementing this technology to improve the efficiency and sustainability of their operations.
