SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).

ThermogravimétrieIndex. décimale : 667.9 Revêtements et enduits Résumé : Three two-layer heat-resistant and anticorrosion paints have been formulated from urethane siloxane binder and traditional anticorrosion pigments such as micaceous iron oxide (MIO), zinc phosphate (ZP), and aluminum oxide. These pigments were used as the dominant components of different undercoats or topcoats. Heat-resistant pigments such as silicon nitride and glass-spheres were used in the composition of the topcoats. Thermogravimetric analysis of paints shows that the paint with ZP as dominant component of the undercoat have the highest heat-resistance and stability in inert gas and oxygen. The paint with a combination of MIO and ZP has the best hardness as well as the best protective and anticorrosion properties based on the electrochemical impedance spectroscopy. A maximum synergic effect of the properties of pigments seems to appear in this paint. Surface morphology of paints was studied by means of scanning electron microscopy. Heated at different temperatures and for several hours, paint containing MIO as the dominant component in the undercoat exhibits the best mechanical and adhesion properties.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Water-soluble hydroxyl functionalized hyperbranched polyester (WH-HP) resin was synthesized using pentaerythritol, pyromellitic dianhydride, phthalic anhydride, and 1,1,1-tris(hydroxymethyl)propane. The synthesized WH-HP was characterized by spectroscopic (FTIR and NMR) as well as thermal (TGA and DSC) analysis. WH-HP and hexa methoxy methyl melamine (HMMM) resins were mixed in different mole ratios (1:2.5, 1:5, 1:7.5, and 1:10), coated on mild steel panel, and cured by baking at 110°C for 1 h. These coating compositions were evaluated for their mechanical and anticorrosive properties. It was observed that coating composition having 1:5 mol ratio (WH-HP:HMMM) has shown very good mechanical and anticorrosive properties compared to the rest.

ThermocinétiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The inadvertent transfer of thermal energy in the form of heat leads to a variety of issues in industrial settings. Issues include heat loss from processing equipment and piping, increased energy usage, worker injuries from contact with hot substrates, and associated costs. The traditional insulation methods to combat these issues include use of materials such as fiberglass and polyurethane foam ; however, thick layers of insulation can often hide severe maintenance problems such as corrosion under insulation (CUI).
An alternative to traditional insulation is the use of thin-film thermal insulation coatings based on waterborne acrylic and epoxy resins. This article describes our efforts to better understand the polymer design and formulation parameters for these thin-film waterborne thermal insulation coatings. Their potential use in thermal insulation will be described through test results on thermal conductivity, safe-touch properties, and corrosion performance in multilayer systems that can be applied by traditional methods. Both one-component waterborne acrylic and two-component waterborne epoxy resins and coating formulations have been evaluated and compared to commercial insulation coatings. The use of two types of low thermal conductivity fillers, hollow glass microspheres and silica aerogel, is also described.Note de contenu : - How heat transfers

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : The mechanical properties of pigmented coating layers are important in a variety of applications. However, the large number of parameters that influence these properties as well as the numerous types of deformations challenge the prediction of the performance of these systems. A discrete element method (DEM) is proposed to predict the mechanical properties of paper coating layers that have a range of starch and latex content. The model is developed in both 2D and 3D and is adapted to tensile and flexural deformations. The model predictions are compared to experimental results in the literature. The predictions are generally good for the moduli and the strain at failure of the systems, but underpredict the maximum stress. This result may be caused by the complex particle size distribution of the experimental systems or by the impact of the brittleness of the starch when making the freestanding films.
