Modern Technology of Surface Coating with Formulae & Their Applications

Surface coating technology specializes in finding out engineering solutions to all the critical production problems related to coating the products on a continuous and consistent basis in your production plant. Surface coating can be defined as a process in which a substance is applied to other materials to change the surface properties, such as colour, gloss, resistance to wear or chemical attack, or permeability, without changing the bulk properties. The development of science and technology revolutionized the surface coating industry in the progressive countries of the world. Surface coating involves different types of products for example paints, varnishes, resins, polyesters, pigments etc. Varnish is one of the important parts of surface coating industry. Varnish is a transparent, hard, protective finish or film primarily used in wood finishing but also for other materials. They are used to change the surface gloss, making the surface more matte or higher gloss, or to provide the various areas of a painting with a more unified finish. Varnishes are also applied over wood stains as a final step to achieve a film for gloss and protection. Some products are marketed as a combined stain and varnish. Paint is any liquid, liquefiable, or mastic composition which after application to a substrate in a thin layer is converted to an opaque solid film. It is most commonly used to protect, colour or provide texture to objects. The paint industry volume in India has been growing at 15% per annum for quite some years now. Alkyd resin is complex oil modified polyester that serves as the film coating agent in some paints and clear coatings. Within the surface coating industry, the name polyester when used alone, indicates polyester free of natural oil modifiers. Such polyesters are used extensively in coatings. There has been considerable impact in this field. We have completely replaced costly petroleum solvent with water and we get cheaper finished products with no evaporation loss and tire hazard. These newer products have enabled paint manufacturers to improve the performance properties of their paints and coatings and so satisfy the more stringent requirements of our modern industrial society. The major contents of this book are past, present future of the surface coatings industry, manufacture of alkyd resins, solvents, organic pigments, paint additives, industrial application emulsion polymers, manufacture of paints, architectural paints, corrosion resistant and chemical resistant paint systems, vehicles for corrosion inhibiting primers, metal lead primers, coal tar epoxy resin, corrosion mechanism, control of corrosion, coating sallylated methylol phenol resins, industrial finishes and many more which helps you to get a complete understanding of the technology of surface coating. Finally this book will help old as well as new entrepreneurs and technocrats to achieve improved performance on various surface coating raw materials as well as finished products.
