RhéologieIndex. décimale : 667.6 Peintures Résumé : Now let us turn our attention to a very important property of Paints viz ; Rheology. It is the study of how materials flow and deform when subjected to externat forces. Rheological measurements therefore define some of the fundamental properties of materials and can be used effectively to characterize and predict product behaviour. For coatings, product behaviour under very different sets of conditions must be well understood and controlled in order for the product to be successful. A coating, for example, must be stable during storage, easy to apply using whatever application process is appropriate, and, ideally, the final surface finish should be smooth and drip-free. All three of these aspects of paint performance are linked to product rheology. As a result, rheological evaluation has become a key step in the development and monitoring of coatings.

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : While understanding the rheology of any formulation, clarity around the core fundamentals enables efficient management of the rheological properties of your product. Let us begin by understanding some fundamentals terms. What is viscosity ? Viscosity and rheology are often confused, and they are significantly different concepts. While rheology is the study of flow, viscosity, a part of rheology, can be obtained from rheological measurements. Viscosity is a measurement of the fluid's resistance to flow and a function of shear rate or stress, with time and temperature dependence. In rheological measurements, the strain rate is related to the measurement of the deformation and stress is related to the measurement of the for required to deform a material. Shear stress (τ; Pa), one of the main parameters studied in rheology, is the force per unit area that a fluid requires to start flowing. Shear rate (γ; s-1) describes the velocity gradient. It is the rate at which a fluid is sheared or "worked" during flow. Note de contenu : - Pseudo-plasticity

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Researchers have developed a new measuring geometry for a rheometer that offers good sensitivity and has no impact on the drying process. The new method helps determine the drying behaviour of paint formulations with different binders and presents a useful tool for formulators to optimise their water-borne paints. Note de contenu : - More sensitive method to viscosity changes
- Experimental
- Drying behaviour differed for surfactant only stabilisation
- Additive pigment interactions key

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.6 Peintures Résumé : Now let us turn our attention to yet another functional paint called Road Marking Paints. Earlier road contractors used to mark the roads viz: the central median, side boundaries and lane separating lines with ordinary synthetic enamel white. According to the state of Michigan, the idea of using a painted centre line was conceived in 1911 by Edward N. Hines, the chairman of the Wayne County, Michigan, Board of Roads, after watching a leaky milk wagon leave a white trail along a road. White Lines painted on the pavement indicate traffic travelling in your direction. Broken White Line : you may change lanes if it is safe to do so. Solid White Line : requires you to stay within the lane and also marks the shoulder of the roadway. Yellow Lines mark the centre of a two-way road used for two-way traffic. This had a very short life in view of heavy vehicular traffic on the roads. Frequent road markings added to the road maintenance costs. Slowly they shifted to water based coatings with good white pigments such as Rutile and higher percentage of Emulsions to give better scrub resistance so that the coating can last longer. They were also used in factory floors as markers or indicators and cautionary signals to guide the people working in the Factory, Airport taxiways, Apron etc. Note de contenu : - Various road marking paints
