UV powders are generally based on unsaturated (meth)acrylate polyesters and urethane (meth)acrylates, photoinitiators and additives (pigments or fillers). All compounds are solids, which make the formulations environmental friendly.
For industrial parquet applications, 100% UV coatings have been very well established as primers, sealers and topcoats for many decades. They combine ultimate productivity, high quality and very low VOC.
The usage of micronized fillers in UV curing parquet lacquers is not common due to lack of transparency. Nevertheless there is the tendency, to use fillers more and more to increase scratch resistance and for cost reduction reasons.

During recent years VOC regulations in Europe keep the wood coating industry moving from classical technologies, e.g. solventborne 2K polyurethane and acid catalysed cure of melamine resins, to modern technologies, such as 100% and waterborne radiation-curable resins.
In te wood industry, the usage of UV technology is well established for the production of doors, flooring and furniture. Compared to conventional processes, UV technology induces ultra fast curing resultings and furniture.
Electron beam (EB) technology has been used in converting applications for more than 30 years. The use of EB is driven by a number of factors including: product performance, product consistency, high throughput, energy savings, and the absence of solvent. The nature of EB
Using life Cycle Inventory, a comperative study of envoironmental performance of some paints for wood application known as surfacer was accomplished. Three differnet kinds were studies: ultraviolet, waterborne and solventborne surfacers.
The consumer's point of view... The only thing the consumer can rely on is the information given by the manufacturer (or the salesman). But unless that information is comparable to something, it will be of little real value. So how can we give the consumer reliable and comparable information?
