Protecting the grain / Michel Tielemans in EUROPEAN COATINGS JOURNAL (ECJ), N° 3 (03/2019)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 3 (03/2019) . - p. 104-109 Titre : Protecting the grain : Sustainable development of new water-based energy-curable PU dispersions for wood Type de document : texte imprimé Auteurs : Michel Tielemans, Auteur ; Guido Vanmeulder, Auteur ; Michela Fusco, Auteur Année de publication : 2019 Article en page(s) : p. 104-109 Langues : Anglais (eng) Catégories : Bois -- Revêtements protecteurs Dispersions et suspensions Liants Polyuréthanes Revêtements -- Aspect de l'environnement Revêtements en phase aqueuse Index. décimale : 667.9 Revêtements et enduits Résumé : Wood is a challenging substrate, vulnerable to surface deterioration through fungal and microbial attack, moisture ingress, tannin staining, and light degradation. Coating manufacturers need to balance durabilty and protection with aesthetics, sustainability and value. Four novel UV-curable polyurethane dispersions combine the best attributes of water-borne polymers and offer key performance benefits that address new market needs. Note de contenu : - Effective curing and high resistance - Low VOC and reduced carbon footprint - Reducing environmental impact - Four new products that eliminate co-solvents - New dispersion morphology outperforms benchmark - Greater resistance using novel binder - Low yellowing on cure for improved colour matching - Excellent price-performance ration and optimised compatibility - Fig. 1 : A straightforward sustainability model for UVPUDs inspired by life cycle analysis - Fig. 2 : A comprehensive product range articulated around binders for primer coat, top coat or self-sealing - Fig. 3 : Performance of UVPUD 1 versus the reference UVPVD 5 - Fig. 4a : Major performance area of UVPUD 2 versus reference UVPUD 5 and reference UVPUD 5 - Fig. 4b : Major performance area of UVPUD 3 versus - Fig. 5 : Major performance area of UVPUD 4 and subsequent formulations with UVPUD 6 & UVPUD 7 - Table 1 : Characteristics of new polymer dispersions En ligne : https://drive.google.com/file/d/1qcTI9v5HmNZxlY5LieBiSl_ff-kGRt2B/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32022 [article]

Water-based, filed-applied, UV-curable topcoats for wood flooring / J. Arceneaux in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 201, N° 4559 (04/2011)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 201, N° 4559 (04/2011) . - p. 20-22 Titre : Water-based, filed-applied, UV-curable topcoats for wood flooring Type de document : texte imprimé Auteurs : J. Arceneaux, Auteur ; Guido Vanmeulder, Auteur ; Stefan Smeets, Auteur Année de publication : 2011 Article en page(s) : p. 20-22 Langues : Anglais (eng) Catégories : Bois -- Finition Parquets -- Revêtements protecteurs Polymères en émulsion Polyuréthanes Revêtements en phase aqueuse -- Séchage sous rayonnement ultraviolet:Peinture en phase aqueuse -- Séchage sous rayonnement ultraviolet Index. décimale : 667.9 Revêtements et enduits Résumé : UV curing provides many benefits, such as increased productivity and performance and reduced energy consumption and emissions. Initially these benefits could only be enjoyed in factory-applied applications due to the nature of the UV curing equipment required. During the past decade, however, significant developments in portable UV curing technology have made field-applied, UV-curable coatings possible. For the wood flooring industry, factory-applied coatings are typically UV-cured due to the advantages described above. while initially 100% solids formulations, UV-curable polyuréthane dispersions in water (UV-(PUD), introduced in the late 1990s, provide improved flexibility, adhesion and stain resistance and with lower viscosities and low-VOC content are attractive for spray, curtain and vacuum applications on to wood. Field-applied, wood floor coatings, until recently however, have required conventional curing, polyurethanes (PU) are the leading type of field-applied floor coatings. Others include conversion varnishes, oils and waxes. Today,j however, there are several UV-curable wood floor coatings in varying stages of commercial development, including 100% solids and waterborne formulations.
