Résumé :	Low viscosity and regulatory compliant (tin-free) prototype offers a robust single-coat spray usage for wood coating applications and ensures the formation of mirror-like coatings with a good hiding power. A new high-solids and solvent-free radiation curable polyurethane dispersion has been developed for high gloss applications with excellent DOI. The product has an excellent colloïdal stability (shelf life of 12 months) and complies with VOC-free, tin-free and stenomer-free requirennents. Due to its low viscosity and its good responsiveness to rheology modifiers, it can be easily applied by spray, roller or curtain coating operation. Its value-in-use was optimised by significantly reducing polymer flow after drying and before radiation curing. The product can be advantageously applied in one single coat and enables one to get rid of sanding step required in between topcoat layers with former products applied in two layers. The cured coating exhibits good chemical and scratch resistance required for high-end wooden furniture top coats — although it can aise be used for other substrates and applications.
