Automotive OEM Coatings
In today's coatings world, automotive OEM coatings are considered to be one of the most demanding applications for high-performance solutions. They are tremendously innovative in terms of materials and processes, providing solutions for better cost efficiency and more environmentally friendly systems as well as being more resistant to various chemical or mechanical stresses.
With its highly specialized product portfolio and broad-based chemicals background, Evonik is a major and essential provider of new solutions for modern automotive OEM coatings.
AEROSIL® fumed silica is mainly used to control rheological characteristics, as a thixotroping agent, as an anti-settling agent, and to help in the prevention of rust and corrosion. Several hydrophilic or hydrophobic AEROSIL® fumed silica grades are available to meet your application needs. AEROSIL® R 9200 a structure-modified silica, acts as an additive that increases the mechanical stability of resins and thus either diminishes scratching or modifies surfaces to be more hydrophobic.
Automotive OEM coatings require superior, high-performance crosslinking technologies. Evonik is a significant contributor in this field, offering polyisocyanate crosslinkers for 2K or 1K thermosetting systems or as powder coatings for superior, scratch-resistant novel hybrid systems based on silane and urethane technology.
High-performance automotive coatings call for high-performance resins. Evonik offers a broad portfolio of monomers for the design of superior resin technology: Aliphatic diisocyanates for water-borne resins like CED and especially water-borne basecoats. VISIOMER® methacrylate monomers provide excellent weatherability and scratch resistance, high gloss, and appearance. Functional silanes can be used for the modification of crosslink density or the chemical resistance of clearcoats.
TEGO® additives provide superior solutions in many respects, such as pigment wetting, flow, and leveling.
