Revêtements -- Séchage sous rayonnement électroniqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Many coating industries come under increasing pressure to reduce energy costs, speed production & comply with strict environmental standards ; many are looking at the innovations of UV/EB technology for solution of the problems. Electron beam (EB) curing involves free radical polymerization, since activation energy in EB is low for chain propagations, high curing speeds can be achieved at ambient temperature. Nano-composite EB curable coatings by incorporation of nano-particles and pigments enhances the coatings properties.

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.Index. décimale : 668.4 Plastiques, vinyles Résumé : Electron beam (EB) processing of pristine and filled polymeric materials is considered as one of the most viable techniques in the development of three-dimensional (3D) network structures of polymeric or composite systems with improved physical and chemical properties. The grafting, or the crosslinking process induced by the merging of the macro free radicals generated during the electron beam modification without the aid of any chemical agent or heat, is responsible for the formation of the 3D networks in polymeric systems. Owing to its distinct advantages such as fast, clean and precise, electron beam (EB) radiation technology takes up a vital role in the crosslinking of polymeric compounds. However, during the course of electron beam treatment of polymers, two processes viz., crosslinking and chain scission take place simultaneously, depending on the level of radiation dose used for the processing. The present paper reviews the role of irradiation dose in the presence and absence of radiation sensitizer on the crosslinking and structure formation in a wide variety of soft matrices such as elastomers, latexes, thermoplastic elastomers and their respective filled systems. Notable improvements in mechanical and dynamic mechanical properties, thermal stability, processing characteristics, etc., of the EB processed elastomers and their composites are discussed elaborately in the paper. Specially, the property improvements observed in the EB processed pristine and filled rubbers in comparison to the conventional crosslinking technology are critically reviewed. The level of radiation dose inducing crosslinking in both pristine and filled rubbers, determined by calculating crosslink to scission ratio on the basis of Charlesby–Pinner equation is also discussed in the paper. Finally, the application aspects of electron beam curing technology with special emphasis to cable and sealing industries as developed by one of the authors are highlighted in the paper.

Revêtements -- Séchage sous rayonnement ultraviolet
Surfaces -- NettoyageIndex. décimale : 667.9 Revêtements et enduits Résumé : With the increasing use of tactile touch interface and high gloss finish surfaces in various market sectors, including packaging, automotive, appliances, consumer goods and teletronics, the need for an easy-to-clean (E2C) surface property is growing and posing a challenge to designers and coating formulators. As a consequence, investigation of these new functional surfaces has gained increasing interest in technical and scientific literature. Yet, the most effective solutions currently available are quite costly and, consequently, only used in high value components such as touch screen displays.
To overcome this high cost barrier, Cytec introduced its latest development for energy curable coatings, namely Ebecryl 8110 resin for consumer electronics components such as casings etc. This novel and patent-pending UV resin enables paint formulators to develop coatings that meet the overall coating performance requirement (hardness, adhesion, chemical resistance) as well as permanent easy fingerprint removal/easy-to-clean surface property.Note de contenu : - Effect of composition
- Effect of application conditions on E2C performance
- Robustness of the E2C property and benchmarking

Considerable efforts have been made to eliminate or reduce the solvent content of these formulations. The aim is to retain typical epoxy properties such as ease of application at room temperature, reliable protection thanks to excellent adhesion, high mechanical and chemical resistance. The article compares new cold-curing binders for high solids, waterborne and solvent-free epoxy coatings, and discusses the high standard that has been attained by epoxy systems to meet ecological requirements.
