High-solids automotive coatings

Manufacturers of automotive repair finishes are tending to reduce more and more the level of volatile organic compounds in their paints in order to co mply with increasingly strict environmental legislation After a review of t he main parameters allowing a viscosity reduction in acrylic resins in gene ral, this paper describes the use of a reactive intermediate called CARDURA E10 (a trade mark of the Royal Dutch group of companies) which is able to reduce the solution viscosity of different resins and, hence, allows to inc rease the solids content of automotive paints while improving the final coa ting properties.
