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

Peinture solaireIndex. décimale : 667.9 Revêtements et enduits Résumé : Continuous decrease of reserves of fossil fuels has sparked a wave of innovation in energy. As the world's energy consumption set to increase 35 percent by 2035, the need to develop renewable and cleaner alternatives is becoming very important. Among wind, water, biomass and nuclear, solar power has a significant role to play, especially in developing areas with high levels of sunlight. Hence the necessity is felt to develop the "solar paint ". The idea is that you can solar-paint on to various surfaces regardless of shape, e.g., sides of buildings, roofs, vehicles and just about any other structure you can think of that faces the sun. Right now, solar paint is not as efficient as silicon-based solar panels and this is the single major hurdle researchers are facing before solar paint is commercially viable. Solar paint is mostly stuck in the single digits — between 3 % and 11 % depending on the technology used. Various universities are working on different technologies to improve the efficiency. In this review those various routes to produce solar paints will be discussed in details. Note de contenu : - Traditional solar cells recent developments
