SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.Index. décimale : 667.9 Revêtements et enduits Résumé : The author discusses a proven method for dispersing fumed metal oxides down to individual particles in water for efficient utilisation in polymer latex systems.
Fumed silica and fumed alumina are examples of nanoscale inorganic additives for waterborne (WB) polymer film and coating systems. Fumed metal oxides can often be difficult to work with because they exist mostly as high surface area powdery agglomerates that are not easily separated or dispersed into individual particels. Cabot's Cab-O-Sperse colloidal scale dispersions are available in a range of concentrations, particle sizes, surface charges and different pH ranges for use in a wide variety of applications. Specifically, Cab-O-Sperse fumed metal oxide particle dispersions provide formulationflexibility to waterborne coatings that can help balance wet formulation processing needs with coating optical, mechanical and chemical performance demands. These dispersions provide a convenient waterborne vehicle for nanocomposite materials.Note de contenu : - State of dispersion

Huile de linL'huile de lin ou "huile de graines de lin" est une huile de couleur jaune d'or, tirée des graines mûres du lin cultivé, pressées à froid et/ou à chaud ; parfois elle est extraite par un solvant, en vue de l'usage industriel ou artistique, principalement comme siccatif, ou huile auto-siccative.
Les utilisations de l'huile de lin dérivent de sa richesse en acides gras polyinsaturés, en particulier en acides linolénique et linoléique, qui lui doivent leur nom.
L'huile de lin polymérise spontanément à l'air, avec une réaction exothermique : un chiffon imbibé d'huile peut ainsi, dans certaines conditions, s'enflammer spontanément.
Pour ses propriétés de polymère, l'huile de lin est employée seule, ou mélangée à d'autres huiles, résines et solvants, et est utilisée en tant que : Imprégnateur et protecteur des bois à l'intérieur comme à l'extérieur : protection contre l'humidité, les champignons et insectes, et contre la poussière par son caractère antistatique, composant de certains vernis de finition, liant de broyage pour la peinture à l'huile, agent plastifiant du mastic de vitrier, agent durcisseur de diverses préparations, agent de cohérence et liant dans la fabrication du linoléum.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The penetration of wood coating primer products into pine and spruce softwood was evaluated with microautoradiography. 14C-labeled binders of alkyd and linseed oil were synthesized and used in eight different products. The penetration front in wood is uneven due to a heterogeneous structure with different types of wood cells. It was demonstrated that conventional solventborne alkyd primers and waterborne alkyd emulsion primers have similar ability to penetrate into wood. Improved penetration was found for products with lower viscosity, such as an alkyd stain and a linseed oil coating. A priming oil had superior penetration. Generally better penetration was obtained for coatings applied onto sawn and rough surfaces as compared to planed and smooth surfaces.

Revêtements:PeintureIndex. décimale : 667.6 Peintures Résumé : The goal of every chemical manufacturer is to ship a quality product to his customer. One common requirement for waterborne products such as coatings is that the product remains microbiologically stable until used, and in some instances, for some period alter its use (paint films for example). Being aqueous, these products are susceptible to microbial contamination and degradation. Anti-microbial (biocides) are routinel y added to assist with the delivery and maintenance of productqualities so that they meet customer expectations. However, it has long been apparent that even adding an appropriate lab tested anti-microbial to the finished product may not be sufficient to accomplish th is goal due to some unseen challenges at manufacturing level which remain out of scope during product development at lab scale. It is now understood that the product must first, and foremost, be manu factured under a tightly controlled process that includes adequate plant hygiene. Doing so m in im izes the final cost of the product and helps ensure that a quality product is manufactured and delivered.
Contamination and cross-contamination in paint and coatings manufacturing is a serious issue. As, it can occur at any point of the manufacturing cycle — during production, processing, packaging, distribution or storage.
This article also details some of the areas of concem in a "generalized" aqueous product (such as coating) manufacturing scheme. The intention is to highlight those areas that are most likely to cause microbial quality problems so that a plant hygiene program can proactively address them. Regular attention to hygiene at the plant will pay dividende to the manufacturing process of waterborne paints.Note de contenu : - Plant hygiene and its importance : Raw materials - Water - Equipment - Cellulosic thickener solution - Mill base - Biocide addition validation & records - Filling line - Packaging material - Storage/transportation of finished gods

SurfactantsIndex. décimale : 667.9 Revêtements et enduits Résumé : A model is presented for the adsorption of a mixture of an anionic and a nonionic surfactant on latex particles. The model is based on the Langmuir equation for adsorption and the regular solution theory for mixed micelle formation. Good agreement between the experimental data and the calculated adsorption was obtained with a mixture of sodium dodecyl sulphate (SDS) and nonylphenol ethoxylate (NPE10). The preferential adsorption of the more surface active NPE10 is greatest at the onset of micellization and diminishes as the total surfactant concentration increases. The composition of the mixed surfactant at the surface greatly depends on the total surfactant concentration and on the surface area/solution volume ratio. This is illustrated by the calculated adsorption equilibria at different conditions. Addition of small amounts of organic solvents (e.g., coalescing aids) increases the critical micelle concentration (cmc) of NPE and decreases the cmc of SDS. The decrease in the difference between the cmc values of the two surfactants is paralleled by a reduction in the preferential adsorption of the nonionic surfactant in the presence of a coalescing aid.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Waterborne 2K polyurethane coatings based on the new generation of cosolvent-free, OH-functional polyurethane dispersions and internally activated polyacrylate dispersions are excellently suited for the use in transportation (eg trains, trucks, buses and ACE market) clearcoats and topcoats as well as for metal, plastic and wood substrates. Depending on the coating formulation, they prove to be hard, yet still flexible, even in cold weather.
Additional values to mention are the corresponding coatings are high-gloss, weather resistant, highly chemical resistant and, depending on the dispersion used, characterised by a pronounced self-healing effect after scratching or are very fast drying, meaning the oven temperature for drying coated objects can be reduced to cut energy costs and CO2 emissions. These new PU and PAC dispersions are already used in the field of general industrial, wood and furniture coating. The dispersions presented here make it possible, using waterborne products, to fulfill or even exceed the requirements imposed on coatings in market segments previously dominated by conventional coating systems and they are very eco-friendly thanks to their low VOC content. A significant expansion is expected in the use of waterborne polyurethane coatings in the medium term. These new building blocks, therefore, will add a new chapter to the overall success story of aliphatic 2K polyurethane coatings.Note de contenu : - Internal activation cuts energy costs and reduces CO2 emissions
