Development of ultra low bake stoving monocoat for industrial OEM application / Sulav Seth in PAINTINDIA, Vol. LXXXIII, N° 11 (11/2023)  

[article]  inPAINTINDIA > Vol. LXXXIII, N° 11 (11/2023) . - p. 54-68 Titre : Development of ultra low bake stoving monocoat for industrial OEM application Type de document : texte imprimé Auteurs : Sulav Seth, Auteur Année de publication : 2023 Article en page(s) : p. 54-68 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Bilan des émissions de gaz à effets de serre Catalyse Composés organiques volatils Copolymère mélamine-formaldéhyde Dépôt électrolytique Haut extrait sec Matériaux -- Cuisson Polyacryliques Polyesters Réticulants Revêtement monocouche Thermodurcissables Index. décimale : 667.9 Revêtements et enduits Résumé : Three eco-friendly solutions are prominent in coating industry especially in the field of Automotive coating. In Indian context, water based coatings are not feasible for its cost & other operational issues, thus it is limited to CED application only. High solid coatings are the next alternate & it is gaining popularly for reduced VOC emission without compromising the physical & chemical properties of the coatings. Simultaneously all OEM manufacturers are seeking solutions for low bake coatings to restrict energy consumption in the curing process which will reduce carbon footprint in the whole supplychain. When we talk about low bake coatings, reactivity & catalysis plays pivotal role in achieving results. Developing a low bake top coat has many challenges. Increased reactivity of the resin system often contributes to uncontrolled & incomplete reaction which is responsible for poor physical, chemical & weathering properties. Use of excess catalyst also has an impact on Electrical Resistivity (ER) which is a very important application parameter for electrostatic spray application. Combination of catalysis & reactivity negatively impacts storage stability. Judicious selection of catalyst, its dose optimization, right combination of crosslinker resin, Base to crosslinker ratio is very important to get desired results. In the current research paper we will explore various aspects of low bake formulation ingredients & their effect on coating performance to develop a low bake glossy monocoat white which meets the performance requirements of commercial vehicle manufacturers.

Electrografting of mixed organophosphonic monolayers for SI-ATRP of 2-methacryloyloxyethyl phosphorylcholine / Bastien Arrotin in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 16, N° 4 (07/2019)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 16, N° 4 (07/2019) . - p. 1121-1132 Titre : Electrografting of mixed organophosphonic monolayers for SI-ATRP of 2-methacryloyloxyethyl phosphorylcholine Type de document : texte imprimé Auteurs : Bastien Arrotin, Auteur ; Jean-Marc Noël, Auteur ; Joseph Delhalle, Auteur ; Laetitia Mespouille, Auteur ; Zineb Mekhalif, Auteur Année de publication : 2019 Article en page(s) : p. 1121-1132 Note générale : Bibliogr.

Poly(2-méthacryloyloxyéthyl phosphorylcholine) Polymérisation radicalaire par transfert d'atome Revêtement monocouche Revêtements organiques Index. décimale : 667.9 Revêtements et enduits Résumé : Nitinol (NiTi), one of the most important alloys for biomedical applications, is still hampered by its surface nickel inclusions, making it sensitive to pitting corrosion and leading therefore to the release of potentially carcinogenic Ni2+ ions. In this work, we assess the impact of the combination of electrografted mixed self-assembled monolayers (SAMs) on NiTi followed by a polymer coating formed by surface-initiated atom transfer radical polymerization (SI-ATRP). The molecular ratio of 11-(2-bromoisobutyrate)-undecyl-1-phosphonic acid (BUPA) to 11-decylphosphonic acid (C10P) on the electroassisted elaboration of the (BUPA/C10P)-NiTi-SAMs has been optimized. A small amount of BUPA (20%) appears to be the most promising condition, as it provides an efficient corrosion resistance and promotes the SI-ATRP of 2-methacryloyloxyethyl methacrylate (MPC). This confers to the surface hydrophilic properties and corrosion resistance close to those NiTi-SAMs when long polymerization times are used (≥ 6 h).
