Recent advances in vegetable oils based environment friendly coatings
In an article, Indian researchers highlight some state-of-the art-modifications of vegetable oils (VEGO) as environment friendly-low or no solvent, high solids, hyperbranched, water-borne and UV curable coatings.
The review provides a handy overall vision of VEGO based environment friendly coatings on a single platform. These approaches can be well employed on those oils that are non-edible, non-medicinal and are left unexplored, unutilised or underutilised to date, thus adding value to an unutilised or underutilised sustainable resource.
Utilising polymers from renewable resources
The overarching goal worldwide for the scientific community is "sustainable development” today, for an everlasting sustainable and green tomorrow. The strategy includes harvesting renewable resources instead of fossil fuels, using environment friendly routes, and engineering material degradation pathways operating under reasonable time frames. The concept revolves around the focal point of "green” or "sustainable” chemistry. In the world of coatings, the idea has already made its debut in the form of environment friendly technologies-low or no solvent, high solids, hyperbranched, water-borne and UV curable coatings, utilising monomers/polymers derived from renewable resources. VEGO constitute mother nature’s most abundant, cost-effective, non toxic, and biodegradable resource. They have been traditionally used for several non-food applications mainly coatings since primitive times. Today, the implementation of the modern technologies coupled with the full fledged use of VEGO based monomers or polymers in the field as raw materials, is an excellent effort toward sustainable future in the world of coatings globally.
The study is published in: Industrial Crops and Products, Volume 76, 15 December 2015, Pages 215-229.
High Solid Binders
High solids are the epitome of high performance and low environmental impact. They are usually the best option where solvent-borne systems would otherwise be the only choice. This book delivers comprehensive knowledge in the field of high solid systems. More especially, it provides an overview of the various classes of binders and ways of transforming them into high solid binders. It lists a broad range of options and approaches for tackling technological and environmental problems. This book addresses the paint and coatings chemists for a better understanding of chemistries and processes involved in film forming hopefully helping in coating design.
