Scratch resistance is one of the most important customer requirements for automotive painting. Scratches occur as a result of a load being imposed on a paint film, which then destroys or deforms it. In order to improve the scratch resistance properties of clear coat, a specially developed molecular that act to accelerate closslinking reaction was added to the clear coat main resin. This developed molecular facilitates closslinking between multiple molecules and creates an unprecedentedly fine molecular structure. The result is a soft, highly elastic, and durable clear coat with improved resistance to light and acid as well as enhanced deformation recovery properties. It requires no special maintenance, prevents luster degradation caused by surface scratches and helps to prolong new-car color and gloss. Developmental Clear Coat is introduced into the flagship of the Lexus range - the LS as Self-restoring Coat in 2009. Presenter Junya Ogawa, Developmental Center

This paper reports solubility, diffusivity and permeability data for soy and rapeseed methyl esters in polyethylene together with comparisons with methyl oleate and linoleate. These data were used to discuss the reliability of predictive models for diffusion and solubility of additive type molecules into semi-crystalline thermoplastic polymers. Presenter Emmanuel Richaud

This study evaluates utilizing an accelerated test method that correlates customer interaction with a vehicle seat where bagginess and wrinkling is produced. The evaluation includes correlation from warranty returns as well as test vehicle results for test verification. Consumer metrics will be discussed within this paper with respect to potential application of this test method, including but not limited to JD Power ratings. The intent of the test method is to aid in establishing appropriate design parameters of the seat trim covers and to incorporate appropriate design measures such as tie downs and lamination. This test procedure was utilized in a Design for Six Sigma (DFSS) project as an aid in optimizing seat parameters influencing trim cover performance using a Design of Experiment approach.
