Titre : Performance capability of waterborne UV-curable emulsion for wood substrates Type de document : texte imprimé Auteurs : Laurie Morris, Auteur ; Katie Gaynor, Auteur Année de publication : 2007 Article en page(s) : p. 72-77 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : Waterborne UV coatings are slowly share in the factory finished wood market as environmental regulations becom more stringent and as waterborne technology improves. The resin technology has advanced significantly in recent yeas as improvements are made in processing, design, and raw material selection. By altering three basic variables of the waterborne UV resin( UV acrylate selection, incorporation type, and modification), suppliers are able to offer a wide variety of products with tailored performancces and behariors. By choosing the appropriately designed UV resin and managing other formulation and application variables, the coating formulator can meet customers needs with the use of waterborne UV chemistry.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Industrial wood coatings encompass several market areas, including furniture, kitchen cabinets, building products, and decorative coatings.
Requirements for these markets largely depend on their field of application.
Exterior performance is focused on high durability and protection against humidity, while interior coatings require properties such as scratch, chemical and abrasion resistance. One of the largest sectors of the interior market is the furniture industry.
Several resin technologies are being used by coatings formulators in this market, including solventborne (SB), waterborne (WB) UV polyurethane dispersions (PUDs), and self-crosslinking acrylics. Several criteria are of importance in considering which technology to use.
Each technology has advantages and disadvantages, and a comparison has been summarized based on the criteria in Figure 1. The dominant technology used in North America is solventborne, including nitrocellulose (NC) and acid cure conversion varnish. These coatings have many benefits, including fast dry time and very high gloss, and they enhance the wood appearance. They are also very economical and can be easily applied by spraying, rolling, curtain coat, and dipping.Note de contenu : - Fig. 1 : Resin technology comparison
