Characterisation of the experimental resins in respect of physical properties was carried out using instruments namely vapour pressure osmometer, rotational viscometer, universal tensile testing instrument (Instron 1123) and differential scanning calorimeter. Performance of the resins was evaluated using fluorescent UV accelerated weatherometer and multi-head glossmeter. The results reveal substantial improvement in drying and weather resistance properties of castor oil alkyd on graft copolymerisation with both, methyl methacrylate and butyl methacrylate. The improvement in these properties is marginally superior in case of MMA grafted alkyds. MMA modification also enhances the mechanical properties of the grafted castor oil alkyd.

The generation of an in-vitro tissue from bovine fibroblasts is carried out using a scatfold to generate a three-dimensional extra-cellular matrix (3D ECM). The development of a biopelt is by an in-vitro production at lab scale in a bioreactor with specific culturing conditions. New methodologies to stabilize the biomaterial generated were investigated. In particular, the biomaterial was stabilized by immersion in solutions of vegetable tannins and cross-linking agents in an aqueous-solvent medium.

Titre : A model for the dehydration of waterborne basecoat Type de document : texte imprimé Auteurs : Paul Henshaw, Auteur ; Tony Mancina, Auteur ; Lindita Prendi, Auteur Année de publication : 2006 Article en page(s) : p. 285-294 Note générale : Bibliogr. Langues : Américain (ame) Tags : Vernis 'Revêtement protecteur' Distribution Concentration Déshydratation 'Copolymère uréthane' acrylate' Polyester Modélisation 'Peinture en phase aqueuse' 'Méthode des différences finies' Index. décimale : 667.9 Revêtements et enduits Résumé : In vehicle manufacturing, a common topcoat process sequence is the application of a waterborne basecoat, partial dehydration, application of a solventborne clearcoat, then curing at approximately 150°C. Anecdotal evidence suggests that under "harsh" (high temperature and velocity) dehydration conditions, a skin can be formed, which can trap excess water in the basecoat. Upon curing, the excess water forms vapor that can burst through the topcoat, leading to surface imperfections, termed pinholes or pops. A forward-time center-distance finite difference model, incorporating only diffusion and evaporation and experimentally determined coefficients, was used to simulate the water concentration in the layers of a paint film. Simulations were conducted at constant temperatures (27°C and 82°C) as well as by using temperature traces from a full-size dehydration oven under harsh (82°C) and gentle (54°C) conditions. The model accurately predicted the overall solids content after dehydration. However, in both temperature scenarios, the surface layer water concentration was less at the low temperature for the same overall solids content. This counter-intuitive finding is attributed to the increase in diffusivity with temperature, which allows water to be supplied to the surface faster in the high temperature run in each scenario. Therefore, this simple diffusion-evaporation model is not suitable for simulating water entrapment leading to popping.
