It introduces a terminology so that the material class 'yield stress fluid' is defined and can be distinguished from the terms `solid' and liquide. This new material classification is based on two criteria, the equilibrium relation and the flow function. In line with this terminology, an experimental procedure for classifying the material behavior is presented. The second key aspect of this paper is a discussion on the proper definition of the term 'viscosity'. The benefit of the differential viscosity over the dynamic viscosity in case of non-Newtonian fluids in general is worked out. This is shown by the most ele-mentary yield stress fluid, the friction element, because it is the basis of the yield stress concept. Its constitutive equations are given for positive as well as negative strain rates and are also able to represent the preyield behavior. The theory presented in this article is also applied to the Maxwell, Kelvin-Voigt, and Bingham element to demonstrate the working principle.

ViscositéIndex. décimale : 668.4 Plastiques, vinyles Résumé : Injection molding machine manufacturers increase the available injection pressures to allow for parts with larger flow path/wall thickness ratios. What is typically not considered, however, is the fact that the pressure also substantially influences the melt flow, and that increasing the injection pressure can be counterproductive in terms of energy efficiency. Note de contenu : - Factors that influence viscosity
- Pressure-dependence of viscosity

ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : Solvent-borne epoxy coatings dominate the marine, petrochemical and infrastructure protective coatings markets. However, current lower VOC epoxy formulations may have high viscosity, poor spray application and reduced corrosion resistance. A novel low viscosity epoxy can provide ultra-high solids coatings with improved sprayability and excellent corrosion resistance. The global marine and protective formulated coating market in 2010 was valued at US$ 12 billion [1]. This market is dominated by the use of epoxy resin systems with a 60 % market share due to the inherent need for corrosion resistance and durability. Polyurethanes, in second place, hold only a 14 % market share.
However, there is still a need for new materials to address the limitations of epoxies. For example, standard epoxy resins are very viscous (or solid) and therefore require a significant amount of organic solvent to achieve sprayable paint viscosities and facilitate application onto substrates.Note de contenu : - Coating formulation and preparation
