Modern UV curing systems for wood and flooring enable short curing times and immediate further processing. With UV and LED UV technologies from IST METZ, high-quality surfaces can be achieved for a wide range of applications – from parquet flooring to industrial wood-based materials.
UV curing of coatings and finishes is well established in the wood and flooring industry. It offers:
short curing times
high surface quality
immediate further processing
application-specific process parameters
This allows production processes to be adapted to different requirements in terms of quality, surface finish and processing speed.
For oak parquet, high heat input during UV curing can cause tannins to migrate out of the wood. This can lead to yellowing of the surface and alter the natural color of the wood. With our FREEcure system the heat input to the wood substrate can be reduced. This can help reduce the risk of tannin migration and associated yellowing.
Benefits of FREEcure for wood flooring:
UV curing with reduced heat input
Reduced risk of yellowing caused by tannin migration
Helps preserve the natural appearance and color of the wood
Suitable for sensitive wood species such as oak
Excimer technology can achieve gloss levels ranging from 2 to 25 gloss units (60°), depending on the process parameters and coating formulation. Using short-wave UV radiation at 172 nm, the excimer lamp induces near-surface polymerization: a microstructure is formed on the coating surface, while deeper layers can subsequently be cured using suitable UV technology.
This process enables matt and abrasion-resistant surfaces without the use of matting agents. Depending on the coating formulation and process parameters, uniform surfaces can be achieved. Due to the low heat input, excimer technology is also suitable for temperature-sensitive substrates such as thin films or wood-based panels.
The in-line excimer systems from IST METZ are available for working widths of up to 4 meters, enabling integration into a wide range of production lines.
