Pune, India, Nov. This is attributable to the surging demand for advanced paints and coatings additives owing to the increasing residential projects and the rising automotive sector across the globe. The global lockdown imposed by government agencies has affected the painting and coating applications across the globe.

Automotive paint is paint used on automobiles for both protection and decoration purposes. Paint application requires preparation and primer steps to ensure proper application. A basecoat is applied after the primer paint is applied. Following this, a clearcoat of paint may be applied that forms a glossy and transparent coating.

The clearcoat layer must be able to withstand UV light. In the early days of the automobile industry , paint was applied manually and dried for weeks at room temperature because it was a single component paint that dried by solvent evaporation. As mass production of cars made the process untenable, paint began to be dried in ovens.

Nowadays, two-component catalyzed paint is usually applied by robotic arms and cures in just a few hours either at room temperature or in heated booths. Until several decades ago lead , chromium and other heavy metals were used in automotive paint. Environmental laws have prohibited this, which has resulted in a move to water-based paints.

Enamel paint is better for the environment and replaced lacquer paint in the late 20th century. High-pressure water spray jets are directed to the body. Without proper pretreatment, premature failure of the finish system can almost be guaranteed.

A phosphate coat is necessary to protect the body against corrosion effects and prepares the surface for the E-Coat.

The body works as a cathode and the paint as an anode sticking on the body surface. It is an eco-friendly painting process. The base coat is applied after the primer coat. This coat contains the visual properties of color and effects, and is usually the one referred to as the paint. Base coat used in automotive applications is commonly divided into three categories: solid, metallic, and pearlescent pigments.

Usually sprayed on top of a colored basecoat, clearcoat is a glossy and transparent coating that forms the final interface with the environment. For this reason, clearcoat must be durable enough to resist abrasion and chemically stable enough to withstand UV light. Clearcoat can be either solvent or water-borne.

One part and two part formulations are often referred to as "1K" and "2K" respectively. These 2K systems are normally applied "off line" with the coated plastic parts fixed to the painted metallic body. Owing to the difference in formulation of the 1K and 2K systems and the fact they are coated in different locations they have a different effect on the "redissolving" of the metallic base coat. This is most easily seen in the light metallic paints like the silver and light blue or green shades where the "flop" difference is most marked.

The terminology for automotive paints has been driven by the progression of technologies and by the desire to both distinguish new technologies and relate to previous technologies for the same purpose. Modern car paints are nearly always an acrylic polyurethane "enamel" with a pigmented basecoat and a clear topcoat. It may be described as "acrylic", "acrylic enamel", "urethane", etc. True lacquers and acrylic lacquers are obsolete, and plain acrylic enamels have largely been superseded by better-performing paints.

The term is common for any tough glossy paint but its use in the automotive industry is often restricted to older paints before the introduction of polyurethane hardeners. Innovations are taking place in paint industry as well. These days, automotive paints come in liquid form, spray form, and powder forms You can prepare a chrome bumper for paint washing with soap and water, wiping with a waxy material, and using sandpaper to remove any rusty content from the surface of a chrome bumper.

You can also spray self-etching primer before applying paint. From Wikipedia, the free encyclopedia. See also: Primer paint. See also: Metallic paint. How to Restore Your Corvette, CarTech Inc. Retrieved How Truck. Categories : Automotive technologies Painting materials.

In this work the influence of different climatic parameters on the rate of gloss reduction was studied for a number of different automotive coatings. The purpose was to improve the reliability of accelerated test procedures by selecting test conditions that improve the simulation of the degradation processes that occur during outdoor exposure. Results from Florida exposure and accelerated exposure tests were evaluated using an acceleration factor based on the light dose needed to cause a certain reduction in gloss. The results indicate that agreement between accelerated tests and Florida exposure is improved when a test sequence simulating acid rain is included in the accelerated test cycle.

Paint is used to decorate, protect and prolong the life of natural and synthetic materials, and acts as a barrier against environmental conditions. Paints may be broadly classified into Decorative paints, applied on site to decorate and protect buildings and other objects, and Industrial coatings which are applied in factories to finish manufactured goods such as cars. The binder resin and solvent together are sometimes known as the vehicle. The binder may be dissolved as a solution or carried as a dispersion of microscopically small particles in a liquid. Paints are formulated according to their proposed use - primer, undercoat, special finishes matt, gloss, heat resistance, anti-corrosion, abrasion resistance.

Sustainability has emerged as a key issue across the globe. While the specific interpretations and implications are complex and can vary among stakeholders, most agree that sustainability entails creating value through environmental stewardship, social responsibility and economic growth — both now and for future generations. Sustainability includes making balanced choices and pursuing solutions that are best for communities, countries, businesses and the world. Rigorous tools such as life cycle assessment LCA are vital to generate insight and promote a more holistic understanding of environmental benefits, burdens and trade-offs.

Presents the view that higher solids clearcoats more than 60 per cent solids appear to be an attractive way for original equipment manufacture and refinish to meet European legislations as of New inventions in the area of low MW oligomers, alternative crosslinking mechanisms and rheology control agents appear to be capable of meeting the automotive and refinish performance levels. New developments in the area of surfactant free copolymerization open a new horizon to formulate waterborne clearcoats with excellent properties and appearance.
