Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : A novel short oil alkyd has been synthesized based on higher proportion of rosin. The parameters for mole ratio, reaction temperature, cooking schedule, catalyst and time of heating have been standardised. The spectroscopic analysis of the polymer has been undertaken. The viscosity of prepared polymer has been determined in polar and non-polar solvent. This alkyd has been used in formulation of stoving paints with carnuba wax instead of conventional stoving paint binders. This novel resin has been used as a binder and the performance & physiochemical characteristics of prepared composition are excellent. The use of wax gives improvement in hardness and resistance to water, alkali and solvents. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11499

ThermodurcissablesIndex. décimale : 667.9 Revêtements et enduits Résumé : Among the various binders used for industrial finishes, thermosetting acrylics (TSAs) are gaining importance. There are two main reasons for this; firstly they possess inherently superior properties; such as water clear appearance, colour retention, good durability, low pigment reactivity, excellent chemical resistance and excellent flexibility. Secondly, thermosetting acrylics provide greater formulation latitude as they can be tailor made to suit specific applications. Presently, thermosetting acrylics are commonly used in the two major forms: (a) Solvent soluble thermosetting acrylics for conventional solids coatings. (b) Thermosetting acrylics for high solids coatings. . In the present work, water-thinnable acrylic resins have been developed wherein water is used in place of volatile organic solvent which is the main source of VOC emission. Water-thinnable thermosetting acrylics are getting more prominence day after day because of their eco-friendly nature, cost effectiveness and superior films performance. However, ordinary water-thinnable thermosetting acrylic resins cure at high temperature (≈120-150°C) and hence involve high energy consumption. Through this work, efforts have also been directed towards developing such water-thinnable thermosetting acrylic resins which can be cured at lower temperature to yield low-cure surface coatings. For achieving this, a series of TSA resins were prepared by reacting 2-hydroxy ethyl methacrylate (HEMA) and acrylic acid (AA) as monomers in butanol as solvent in presence of benzoyl peroxide as initiator. The prepared TSA resins were made water soluble by neutralizing with ammonia solution. The coating films-were then baked at 90°C for 30 minutes to effect film cure. Cured films were evaluated for their various optical, mechanical and chemical resistance properties to ascertain the commercial utility of low-temperature curable water-thinnable TSA resins.
