Automotive Refinish Applications

UV curing of automotive refinish coatings represents a powerful tool providing a fast curing process and improving the productivity of paint shops. The

Exterior-grade alkyd-cellulose nitrate blends are used in large volume for metal finishing and for automotive refinishing applications. The durability and gloss retention of exterior lacquers are the most important factors contributing to their marketability. 

Thermoplastic acrylics are used extensively in aerosol lacquers, both as solid colours and metallics, in touch up automotive refinish applications. Due to their excellent colour, colour retention, rapid drying, relative inertness to metallic and fluorescent pigments, and exterior durability, they are also used for small household jobs such as repainting furniture (chairs, stools), metal coatings, marking paints etc. 

Nitrocellulose-based lacquers often contain short or medium oil alkyds to improve flexibility and adhesion. The principal applications are furniture coalings, top lacquer for printed paper, and automotive refinishing primers. 

Versions which function in aqueous media are also used in automotive refinishing metallic paint to give high viscosity immediately after application to prevent sagging and aluminium flotation. Their use has enabled the development of water-borne car refinishes, which might otherwise only have achieved solvent reduction by the high solids route. 

The refinishing side of the automotive market is growing considerably faster, because the applications have been developing over the past decade and represent numerous advantages, such as efficiency and improved environment, due to drastic reduction of the use of solvents and due to improved practices. 

Special-purpose coatings are formulated for special applications or extreme environments and include automotive and machinery refinishing, high-performance maintenance, road markings, marine (bridge) maintenance, crafts, metallic and multicolored coatings. 

P.Y.139 - opaque forms Paliotol Yellow L 2140 HD offers the optimum in terms of hiding power, brilliancy in full shade, outdoor durability and rheological properties, unfortunately at the expense of reduced colour strength. The pigment is the product of choice for lead-free high grade industrial and automotive OEM and refinish reddish yellow paints. It is stable even in automotive waterborne systems. On fresh concrete and similar applications, however, it cannot be used.
