Souplesse (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Vegetable oil modified urethane (OMU) has been widely used in wood flooring applications for many decades. Due to tightening volatile organic compound (VOC) regulations in recent years, the market has been slowly shifting towards waterborne systems. However, most of the current waterborne OMUs either still contain N-Methyl-2-pyrrolidone (NMP), or the VOC is still relatively high at 135–250 g/L, while the nonvolatile (NV) content is relatively low at 32–38% and thus requires multiple coats to achieve performance properties.1 This article demonstrates a recent breakthrough in the development of a novel NMP-free waterborne OMU with a VOC <100 g/L and a high 45% NV content that maintains the exceptional performance properties of traditional solventborne and waterborne OMUs in the market. Its potential applications include but are not limited to high performance clear wood floor coatings, conformal coatings, air dry, and force cure coatings. Note de contenu : - Dry time

VernisIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Radiation curable formulations have been developed for use in preparation of finishes suitable for patent leather. Curing can be achieved by either ultraviolet or electron beam irradiation. In contrast to conventional methods, complete finish application is obtained rapidly, without the use of heating ovens, and with no air pollution. Patent leather produced by this process exhibits good gloss and flexibility and excellent abrasion resistance. Flexibility was affected by the type and amount of crosslinking agent incorporated into the coating as well as by the acrylated urethane oligomer used as the coating backbone. The effects of varying the formulation on final finish properties are discussed. Note de contenu : - TABLE I : Variation of gloss with coating thickness

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : The requirements in terms of outdoor durability in the joinery market have increased significantly over the past years. High performance waterborne dispersions have been developed for this purpose. BASF continues to develop products which can meet these stringent performance requirements. The first waterborne UVA/HALS blend using proprietary NEAT technology has been recently launched.
This product fulfils these high-end requirements as it is composed of a high performance UV absorber and a non-interacting HALS, making it compatible for all resin types, especially sensitive resins.
This novel blend offers a superior photo-permanence and it not only improves the durability of the wood but also the performance of the wood coatings in terms of superior colour and gloss retention.
The NEAT technology allows an additional step forward in the reduction of VOCs. The new product is solvent-free and does net require any co-solvent for its addition into the formulation.Note de contenu : - Novel encapsulated additives technology - neat

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 668.4 Plastiques, vinyles Résumé : One-shot manufacturing of injection molded parts with high-gloss hard lacquer coatings, sophisticated depth effects or structured surfaces with a convincing tactile effect is no longer just a vision. After several years of development work, a project aimed at vehicle interiors is showing that the "ColorForm" process allows these aims to be met with virtually zero rejects and at favorable costs.
