Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Scientists discuss the dramatic changes, which have taken place with pavement marking technology.
Marking paints for pavement surfaces used in roads, airfields and parking lots have been around for over 80 years but the technology has changed dramatically over that time. There has been a shift from the early days of oil-modified phenolformadehyde resins to alkyds, chlorinated rubber and solvent-based acrylics to today's more environmentally advanced and higher performing waterborne acrylic traffic paints. The binder breakthough which enabled the widespread use of waterborne paints was the invention of a pH triggered, quick set mechanism for faster drying waterborne paints, espacially under high humidity and low air flow conditions. Waterborne polymers continue to advance in terms of adhesion to surfaces and retention of reflective beads for night visibility.
More recent progress has enable the application of waterborne pavement marking paints under near freezing temperatures. Reflective beads have advanced along with the paint binder, providing waterborne pavement marking systems with significantly improved visibility on wet surfaces. The environment, employee safety and road safety all stand to benefit from the continuing improvements in waterborne pavement marking.Note de contenu : - Pavement marking function

Revêtements décoratifs:Peinture décorativeIndex. décimale : 667.9 Revêtements et enduits Résumé : Legislation is limiting the use of potentially harmful constituents, particularly in chemicals and related industries. Decorative paints for architectural applications are the subject of specific (VOC) contents, for example, both to help improve air quality as well as to reduce health risks. Manufacturers throughout the coatings industry are working hard to make their products more environmentally sustainable whilst maintaining performance. The main challenge for paint formulators in the industry is to differentiate thermselves from competitors, with performance improvements and more sustainable solutions.

Chimie industrielle -- Aspect de l'environnementIndex. décimale : 667.9 Revêtements et enduits Résumé : In a world of green revolution, only a little is left untouched. Biocide producers along with other parts of the chemical industry all over the world are currently focusing on projects to make their products more environmentally compatible and to promote their benefits and greener practices. Biocides are used in a variety of applications including paints and coatings, stucco/plasters, polymer emulsions, adhesives and sealants, inks, plastics, wood treatment and many more. The biocide producers have to cope with a highly variable demand of the biocidal product consuming industry, the heightened awareness of the danger of germ growth (bacteria, fungi, algae etc), increasing regulatory measures and fluctuating raw material costs. Regulations with regard to the production and application of biocides are affecting the biocide market in several way, as they are often restricting the use of biodical products and increasing the costs of the time-consuming support of biocides under new regulations. As a result, a couple of biocides are being withdrawn from some applications and traditional chemistries are being replaced with new products. While the regulations in Europe, America, Asia and other parts of the world are becoming more stringent, officials agree these changes will benefit the global biocide industry. Meeting the additional regulatory requirements will protect consumers and, in the long term, will benefit all stakeholders, customers and product manufacturers. Note de contenu : - Challenges ahead

Réduction des composés organiques volatilsIndex. décimale : 667.9 Revêtements et enduits Résumé : One of the most important recent challenges in the coatings industry is to provide greener, environmentally friendly, low VOC coatings while at the same time maintaining the self-life of products through the addition of biocides. This requires specialised biocide products which have been thoroughly researched and developed to reduce their environmental impact while retaining thei efficacy. Currently, many of the biocides used in the coatings industry are based on formaldehyde because of its excellent preservation properties. Note de contenu : - Volatile organic compounds (VOCS)

PigmentsIndex. décimale : 667.9 Revêtements et enduits Résumé : Modern chemistry and innovative processes have made tailor-made pigments for inkjet printing available. Practically all customer requirements can be met by modification during pigment synthesis and specific post-treatment. It is therefore not surprising that inkjet printing is increasingly replacing conventional processes in the large format sector and is becoming established in completely different areas such as packaging.

ViscositéIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In this paper, we assesse the effects of polymer/surfactant interactions in a pigmented water-based dispersionusing rheology, so, it was noted that :
1. Higher levels of ethoxylation led to much lower disper-sion and ink viscosities, and minimisation of pseudo-plastic behaviour.
2. Higher levers of ethoxylation led to higher polymer solution viscosities.
3. In general, with the exception of the octylphenol ethoxylates, more hydrophobie polymers and surfactants decreased the acrylic solution polymer viscosities to a greater degree, possibly due to a screening effect and conformational changes in the polymer.
4. For a given hydrophobe, higher ethoxylation levels led to lower viscosity and elasticity and generally higher print strength in inks.
5. Difunctional surfactants can lead to bridging effects, increasing polymer solution viscosities as well as dispersion and ink viscosities.
6. Lower dispersion viscosities allow for higher pigment loadings during manufacture.
7. Extensional properties have to be considered in the future to fully understand what is occurring.
The interactions between polymers, surfactants and pigments can be useful or detrimental to the characteristics of a formulation depending on its end use. Effects on rheology, adsorption at pigment/vehicle interfaces, and surface tension are common. Formulating with surfactant/polymer complexes that have the ability to nnodify the rheology of the system or enhance adsorption at the pigment surface can provide synergistic benefits. These will lead to better printability and press performance.Note de contenu : - Polymer solutions

Formulation (Génie chimique)
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.
