It is capable of being incorporated into low volatile organic compound (VOC) formulations and combines good appearance, film formation and toughness with excellent hardness and abrasion resistance. In this study, we have evaluated the self-crosslinking PUD in various applications ; from high performance wood coatings to protective coatings for rigid plastics and as a top coat for metal. In this paper, we demonstrate the application properties of this resin, such as its hardness development, resistance to chemicals, adhesion, weathering etc. We also validate the versatility of this resin in several applications and assess the film formation and mechanical properties of the PUD. Lastly, we discuss how these influence the performance of the coatings. Note de contenu : - A) FURNITURE AND FLOORING MARKET (WOOD COATINGS) : Formulations and application

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Although solvent-based coatings are prominent in industrial applications, environmental regulations are pushing coating companies and formulators towards water-based systems". Industrial coatings include applications like household appliances, construction machinery, garage doors, fitness equipment, kitchen flttings, industrial joinery, etc. These are mostly applied on metal and the main function is to protect the substrate and make it aesthetically appealing. Other properties that industrial coatings need to have are adhesion to metal, block resistance and high gloss. In this area, we have benchmarked PUD prototype with PUD A and PUD B in white pigmented formulations. Additionally, we have compared PUD prototype to PUD C, which is a commercially available self-crosslinking PUD marketed for metal and plastic coatings. Table 9 summarises the properties of the resins in this application Note de contenu : - INDUSTRIAL COATING APPLICATIONS : Formulations and application - Application testing on CRS gloss and hardness - Adhesion - Chemical resistance - Block resistance

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Compared with solventborne systems, traditional waterborne parquet coatings lack various properties such as scuff- and chemical resistance. Several approaches have been investigated in the past to overcome these drawbacks, but many of them where not totally successful. News generations of raw materials for manually applied parquet coatings (waterborne one- and two-component) and industrial application (UV-curing parquet coatings) were developed. Each represents remarkable progress in its particular field of application. These new systems are discussed with respect to their properties and polymer structure. Note de contenu : - WHAT IS PARQUET
