Spectroscopie d'absorptionIndex. décimale : 667.2 Colorants et pigments Résumé : With an annual consumption of around one million metric tons, synthetic iron oxides are the most important group of inorganic colour pigments. Although these products have already been used very successfully to colour a wide range of materials for many years, their colouring mechanism (causes of colouring) has not been described sufficiently to date. In the case of inorganic pigments, colouring is commonly produced by a combination of light absorption and diffusion in the visible spectral range. This publication offers a detailed description of colouring for red, yellow, orange and black iron oxides. It is explained using structural features of the respective iron oxides and findings from ligand field and molecular orbital theory (MO theory). The tests performed were carried out on phase-pure iron oxide pigments that are grouped together with selected properties in Table 1. Note de contenu : - TESTS ON IRON OXIDE RED PIGMENTS : 1.

Matériaux -- AllègementIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The motor car has been with us for more than 120 years and today it is hard to imagine life without the motor car. It has transformed our way of life, our landscape, and our outlook. Worldwide it has provided mobility, pleasure and economic opportunity to millions of people, but its widespread use has damaged the environment. Now the big question is how sustainable is the motor car, and the way we use it? The European Commission is committed to reducing CO2 emissions from new cars and vans sold in the European Union, to ensure that the EU meets its greenhouse gas emission targets under the Kyoto Protocol and beyond. To meet the targets requires some fundamental changes in the way cars are assembled, used, and – ultimately – disposed of. Adhesive bonding is one of beneficial factors in car production since it helps to reduce the vehicle’s weight, and thus also the CO2 emission, of the finished car. Moreover, it has also proved to be the most energy efficient joining technique. A lighter car generally emits less CO2. But modern cars also need to display ever more innovative and functional designs and continously improve the safety of the passengers. In order to achieve these various goals, whilst also limiting the overall weight of the car, many different materials – such as aluminium, magnesium, steel, or fibre-reinforced plastics – need to be used. Joining all these different parts and materials to make a complete car can only be done with the help of adhesives, since traditional joining techniques like welding, riveting and clinching might damage the material and cannot be applied on all substrates. Increasingly, vehicle manufacturers are using plastic in doors and other vehicle body parts, while most use plastic in bumpers. Tooling for plastic components generally reduces costs and requires less time to develop than that for steel components and therefore may be changed by designers at a lower cost, making it an attractive material for vehicle makers, despite its higher cost per pound. The relative low weight also contributes to higher fuel efficiency in cars. Not only the car body, but many exterior and interior components, visible or hidden in a car, owe their functionality to state-of-the-art adhesive technologies. Overall the energy spent per bonding application with adhesives is lower than the energy spent for conventional joining techniques like welding or clinching. Adhesive bonding increases the choice of material used and enables more innovative designs; both are important factors for the safety of the car. For example, the windscreen provides structural strength to the car body and helps keep passengers inside the car if an accident should occur. The use of adhesives in car production contributes to improving safety standards and allows modern design with innovative material. Adhesives help the car industry to meet its challenges of developing more environmentally friendly solutions for the future. Note de contenu : - And what of the future

Revêtements de solsIndex. décimale : 667.9 Revêtements et enduits Résumé : UV curable field applied coatings for wood (restaurants, shops and residential settings), vinyl composite tile (VCT; hospitals and office buildings) and concrete (warehouses and factories) are in various stages of commercial development. For all these substrates, UV-cured coatings provide many advantages over conventional epoxy, polyurethane and related systems with respect to both application and performance properties. Improvements in both portable UV curing equipment and resin technologies are driving the further adoption of field applied UV-cured coatings in all of the above flooring applications. Most recently, new resins have been introduced that change colour to indicate both coating thickness and cure, increasing ease of application and providing greater efficiency and cost savings.

Vernis bi-composantIndex. décimale : 667.9 Revêtements et enduits Résumé : Evonik has developed a new and versatile product family of crosslinkers/binders for high performance wood coatings. The innovative approach combines the benefits of silane chemistry with the performance of polyurethanes enabling excellent scratch resistance, while maintaining urethane properties in coatings. 3-Isocyanatopropyltrimethoxysilane (IPMS) is the core building block of the novel technology platform and responsible for a high freedom of design creating tailor-made binders and crosslinkers. The resin concept also enables non-isocyanate (NISO) technology exhibiting and exceeding polyurethane performance. This technology can be realised generally in one and two component coating formulations. Modern aliphatic 2K-polyurethane wood coatings are considered as today's benchmark to environmental etch, durability and are, in general, well-known for their excellent balance of flexibility and hardness ? Furthermore, superb overall properties and good adhesion to wooden substrates are advantages, which helped the technology to set the benchmark in the wood coating industry in the last decades. Here, especially the multilayer coatings, which are easy to use with their universal use in sanding or filling primer and top coat.

Mesure
NormalisationIndex. décimale : 667.9 Revêtements et enduits Résumé : ISO has made the first step by renewing ISO2813. However, this solves just a part of the problem. The main issue is with the primary standard. All data are currently derived from just one reference, a quartz-glass wedge with no proof for the assumed linearity. Ideally a series of reliable reference materials would be developed and defined in order to prove and secure gloss references over a range of values rather than just one or two points. A series of references would also prove or disprove the assumed linearity of the calibration line. Thorough scientific research seems to be required to define the effects of roughness and wavelength in order to develop a primary-standard that puts ISO and ASTM in-line and that leaves no room for questions. Ideally these primary standards are of an accuracy level at least tenfold better than those of today's commercial glossmeters. Scientific research on a global definition of gloss would be of great use to the industry. All specifications on gloss should be checked for feasibility and correctness. Although gloss is a generally accepted appearance criteria for quality control in many indutries, recent revelations on gloss standards require us to rethink the way we consider the accuracy of our obtained results.

Composés organiques semi-volatils
Etiquetage écologiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The definition of an SVOC in accordance with the Ecolabel clearly states that the upper SVOC limit is based on the elution of the compound relative to n-docosane on a non-polar column or methyl palmitate on a polar column. Using the boiling point as guidance can be very misleading for some compounds. Although there is a relationship between boiling point, volatility and elution on a GC column, there is not necessarily a direct correlation. If a coatings manufacturer is unfamiliar with VOC/SVOC/non-VOC classification based on elution on a GC column, they should seek guidance from the supplier to obtain confirmation on the status of the compound rather than relying on boiling point guidance. Formulating with Eastman Optifilm enhancer 400 will help to eliminate the need for extensive re-formulation and will offer the formulator a simple, cost effective way to create a low-odour, near-zero emission coating that can meet the requirements of many of the mandatory and voluntary labelling schemes present in Europe at this time.
