Accelerated weathering of oligomers by UV-B / Inwhan Oh in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 210, N° 4666 (12/2020)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 210, N° 4666 (12/2020) . - p. 18-21 Titre : Accelerated weathering of oligomers by UV-B Type de document : texte imprimé Auteurs : Inwhan Oh, Auteur ; Hak-Yul Kim, Auteur ; Sungseo Cho, Auteur ; Indrajit Bhattacharya, Auteur Année de publication : 2020 Article en page(s) : p. 18-21 Langues : Anglais (eng) Catégories : Copolymère uréthane acrylate Essais de résilience Oligomères Photoréticulation Polymères -- Effet du rayonnement ultraviolet Polymères -- Détérioration Polymères aliphatiques Index. décimale : 667.9 Revêtements et enduits Résumé : Ultra Violet (UV) energy curing is one of the fastest crosslinking techniques used to dry coatings. UV curable coatings are also one of the most environmentally friendly coating systems as they are typically solvent-free (extremely low VOC/HAPS). Oligomers being almost 100% solids (ppm level solvent residues) have low to medium average molecular weights. Hence, they are liquid at room temperatures. Some oligomers contain some monomers to help reduce their viscosity, to make it easy for the formulator to handle them. However, some industry players do not believe UV curing is really a good solution for outdoor durable coatings. Hence, Miwon Specialty Chemical Co Ltd (MSC) decided to study the performance of some its aliphatic urethane acrylates under accelerated conditions to determine their durability. This paper discusses the tests and the performance that can be achieved when certain well-designed oligomers are exposed to harsh conditions.

Adhesive curing without side effects in ADHESION - ADHESIVES + SEALANTS, N° 1/2016 (2016)  

[article]  inADHESION - ADHESIVES + SEALANTS > N° 1/2016 (2016) . - p. 13-15 Titre : Adhesive curing without side effects : Maximum intensity limits process speed Type de document : texte imprimé Année de publication : 2016 Article en page(s) : p. 13-15 Langues : Multilingue (mul) Catégories : Colles:Adhésifs Diodes électroluminescentes Photoréticulation Polyacrylates Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Maximum intensity limits process speed - In many industries, light-curing adhesives are essential as they speed up production processes. In recent years the time they take to cure has been cut even further, thanks to the progress made in LED technologies. Intensities can now get so high that this actually counterproductive for some adhesives. Note de contenu : - FIGURES : 1. Maximum intensity was only achieved with a comparatively strong intensity of 1500 mW/cm2 - 2. From 100mW/cm2 the curing is complete - 3. In excess of 500 mW/cm2, after a minimal initial acceleration, the reaction decelerates - TABLE : Mechanical values of acrylate adhesive 3 at different exposure intensities En ligne : https://drive.google.com/file/d/1rGsucjScQM1QnoyuoijHkEKF_dVcb1LZ/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=25752 [article]

At the same time, however, this also increases the need for quality assurance and characterisation methods that are adapted to the actual curing process. UV-assisted rheology has great potential for this.

LED curing is expanding into sectors of the printing and coating market. Adoption of LED curing technology is most readily seen in areas that a small curing area is needed or the presence of heat in the curing process produces problems. The first part of this article contains overview of UV LED lamps and also the technology. The second part of this series provides challenges and benefits of UV LED lamps and also the comparison of LED and mercury lamps. This article will also focus on understanding and measuring the output of UV-LED.
