Vernis -- AdditifsIndex. décimale : 667.7 Cires, laques, vernis Résumé : Automotive coatings have witnessed a definite transition to greener technologies over the past decade. Paint lines are being built or retrofitted for consolidated paint processes, with the intent to reduce energy consumption and operating cost. Specific to automotive clearcoats, there is a move to a one-pass application and a continuing shift to higher solids clearcoats. Consolidated paint processes require a clearcoat with improved strike-in resistance, better flow/leveling, and "filling" power to cope with telegraphing from imperfect substrates. One-pass application requires a clearcoat with an improved sag/flow balance. This article illustrates the improved appearance achieved by the use of cellulose ester rheology additives, alone or in combination with other rheology modifiers, in automotive OEM 1K clearcoats. Electrostatic rotary bell application was utilized to assess clearcoat appearance. Flow and leveling were characterized by a BYK Wavescan Dual. the viscoelastic behavior of clearcoats during the film drying process was investigated using a novel rheological technique, and the speed of solvent release was monitored using thermogravimetric analysis (TGA).

Vernis -- AdditifsIndex. décimale : 667.6 Peintures Résumé : Interest in the use of nanoparticles of iron, titanium, aluminum, and zinc oxides in transparent coatings for wood is increasing. Such nano-composite coatings have the potential of not only preserving the natural color of the wood, but also stabilizing the wood surface against the combined degradative effects of sunlight and moisture. The nanoparticles can be used as additives to coating formulations or deposited directly as thin films on a substrate. Thin film deposition can be accomplished by plasma-enhanced chemical vapor or by sol-gel deposition. This paper describes sol-gel deposition of a hybrid inorganic-organic thin film on wood using a mixture of metal-organic precursors and its effect on weathering properties of the wood surface.
