VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Auto refinish coating market is moving towards Polyurethane based products because of its superior performance, finish, durability, and exhaustive shade choices. Auto refinishing demands different qualities from paint. An auto finish has to be soft enough to allow the polishing out of dust and minor imperfections. Polyurethane proved right choice for this need.
Covestro provides a wide range of solvent-borne and waterborne systems that achieve the processing standards needed for refinish coatings as well as the high-quality performance to match factory-applied coatings. With increasing environmental awareness and stricter legislations, coating manufacturers have started investing in waterborne, high sol ids technology. Solvent-reduced high-sol id polyurethane coatings systems known as 'Polyaspartics' offer the lowest possible solvent content and the fastest curing.
Covestro offers water-borne polyols and polyisocyanates for clear coat and basecoat formulations that fulfill the highest standards for car refinish coatings and help reduce the solvent content of coating formulations.Note de contenu : - RISE OF POLYURETHANES IN CAR REFINISH COATINGS MARKET

Primaire (revêtement)Index. décimale : 667.2 Colorants et pigments Résumé : High performance coatings require high jet-black pigments, but achieving this high colour strength is a challenge with new formulations technologies such as waterborne and HAPS-free.
Carbon black is used in many types of coatings applications, but it's the automotive application that is the most demanding.
When developing high-colour performance automotive base-coats, the coatings formulator is still faced with long and costly dispersion times. And, the challenge of dispersing and stabilising high-colour carbon blacks is made more difficult due to changes in coatings technologies driven by environmental (VOC) concerns.
Because new waterborne technologies can reduce VOC emissions by half - verses conventional solventborne base-coats 1 - formulators in Europe and North America have been transitioning to waterborne and HAPS-free automotive base-coats. Europe is leading the shift towards environmentally friendly automotive coatings technologies, followed by North America. Japan is also making plans to move towards waterborne and this trend will find its way to other major automotive markets, such as Asia Pacific and South America.Note de contenu : - Technology shift

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : Although several methods exist for determining the metallic zinc content of the zinc dust pigment in inorganic and organic zinc rich primers, no generally recognized method exists for the analysis of the metallic zinc content in the dried films of such coatings. This paper demonstrates a rapid and precise method, based on differential scanning calorimetry, for making this determination.

Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

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

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : Fine zinc powder was recommended for use in paints as long ago as 1840. But it is only in the past 50 years, with the development of zinc-rich paints based on synthetic and inorganic paint resins, that zinc powder has become commonly used, specifically in paints for heavy-duty corrosion protection.
The main applications for coatings containing zinc are the long-term corrosion protection of industrial and marine constructions (such as steel infrastructure, pipelines, bridges, windmills, and offshore drilling platforms) and the temporary protection of steel sheets (shop primers) during newbuilding of ships. Zinc coatings are specified in standards such as ISO 12944, Norsok M-501, SSPC-Paint 20, and the new IMO Performance Standard for Protective Coatings (PSPC).
Zinc primers are considered to be the most effective anti-corrosion paint systems in use and have proven their excellent performance over many decades. The thickness of the zinc primers can vary between 10 and 120 microns ; the higher the thickness and the higher the zinc powder content are in the paint, the longer the corrosion protection of the steel will last. This article reviews types of zinc powder and how they are made, types and composition of zinc primers, the corrosion protection mechanisms of zinc primers, suitable uses of the primers, and tips on application.Note de contenu : - Zinc powder : the main constituent of zinc primers
