ThermodurcissablesIndex. 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.Note de contenu : - Technology feasibility in Indian market

Rhéologie
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.
Vapeur d'eauIndex. décimale : 667.9 Revêtements et enduits Résumé : Although thermoplastic dispersions have reached a high level of sophistication, there is a place in the market for the more environmentally friendly alkyd emulsions where high gloss can be obtained without cosolvents, amines, and the like. Water, alkyd, nonionic surfactant, and the appropriate equipment is all one needs to make a clear varnish with >85% gloss under 20°, dry in three to five hours.
With the present state of technology, it is unlikely that alkyd emulsions can match the performance of the present solvent-based siliconized alkyds and other extreme outdoor durable systems.
Beacause of their more conventional permeability behavior and the higher applied layer thickness, high solids seem more suitable for this purpose. Going to the lower end of the market, high-solids systems can be applied in specific segments, taking into account limitations like its price, hardness development, and yellowing characteristics. For the lowest segments (primers and stains), their application will be limited. It is in these segments that acrylic dispersions have acquired a good reputation, for both their performance and price have been accepted by the do-it-yourself market.
In the middle section, ranging from normal outdoor durable alkyds to the better performance stains, alkyd emulsions can be positioned. Their versatility and excellent environmental score (no volatile organic components are necessary) make them exceptionally suitable for this.Note de contenu : - THE ENVIRONMENTAL ISSUE : Workers versus environment - Water versus air protection - Controlled versus uncontrolled application

ZéolitesIndex. décimale : 667.9 Revêtements et enduits Résumé : Since a long time, work has been carried out of how to make coatings eco-friendly so that they don't bring any serious problem for the future generations and mainly for the sustainable development. In this paper various coatings are discussed and about what makes it to be called ecofriendly and their modification to make them so. It also focuses on the cost-efficient and environmental friendly coatings. Coatings like poly urethane, ceramic coatings etc were discussed based on their properties and their behaviour and effect on environment. It also discusses various ways to test its behaviour and modifications that can be done. Ceramic coatings are among the most durable materials, underlying the performance and extending the service life of equipment parts that must operate reliably in harsh environments, including aircraft landing gear, tractors, oilfield pumps, and gun tubes. However, in the mid- 1990s, processes that could apply wear-resistant coatings and that were environmentally friendly had not been developed. But now a days various methods are developed for the same. Note de contenu : - Study and discussion of various types of coatings

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Solvent-based epoxy coating systems for the protection of steel and concrete have been successfully used for many years. 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.

In the first paper of this study, the effectiveness of new APE-free emulsifying agents to generate stable oil-in-water alkyd emulsions containing small particle size between 180-500nm and solid content ranging from 45-72wt% was presented, as well as the technical performance of waterborne enamels formulated with those oil-in-water alkyd emulsions.
In the second part of this study, a comparative evaluation of the environmental performance accessed through LCA (Life Cycle Assessment) of waterborne enamel and conventional solventborne enamel is presented.Note de contenu : - EXPERIMENTAL : Enamels En ligne : https://drive.google.com/file/d/14IXOhpwZDs8wUbzI4dBWmwtVyyNU4Egy/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27322
