Synthetic enamels - Direct to metal (DTM) / Mukund Hulyalkar in PAINTINDIA, Vol. LXIX, N° 11 (11/2019)
[article]
Titre : Synthetic enamels - Direct to metal (DTM) Type de document : texte imprimé Auteurs : Mukund Hulyalkar, Auteur Année de publication : 2019 Article en page(s) : p. 128-130 Langues : Anglais (eng) Catégories : Application directe sur le métal

Revêtement émail:Peinture-émailIndex. décimale : 667.9 Revêtements et enduits Résumé : This is totally new concept to save money on labor cost materials. Concept is similar to high build paints mor DFT in single coat. Which acts as primer as well ass finishing coat. It is formulated in such a way that it gives anti corrosive properties of primer as well and it is made with surface tolerant properties also and in addition fast dring to avoid dust accumulation and mild corrosive atmosphere like industrial area structures, buildings near sea shore, heavily raining areas like hill stations. In short, paint is in between primer and top coat.

Titre : Water-based coatings powered by NANO-VpCI Type de document : texte imprimé Auteurs : Ron Camp, Auteur ; Margarita Kharshan, Auteur Année de publication : 2015 Article en page(s) : p. 20-22 Note générale : Bibliogr. Langues : Anglais (eng) 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.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Today's waterborne coatings are steadily approaching to fulfil several requirements that are usually met by solventborne systems (good adhesion, corrosion resistance and improved weathering). Aqueous technologies are generally preferred over their solvent-based counterparts due to ease of application, lower VOCs and cost. However, waterborne coatings still struggle to provide long term protection for metals in extremely corrosive environments.
Through research it has been found that combining Vapor Phase Corrosion Inhibitors (NANO-VpCI) with a non-zinc environmentally friendly metal complex inhibitor, will significantly improve the long-term corrosion protection of acrylic paints on steel substrates ; the combination of these inhibitors provides a synergetic multilayer defence of corrosion resistance through passivation and film formation.En ligne : https://drive.google.com/file/d/17vNymsezs-LNOKdzjs1MxyFaoraFQ80n/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=22962

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Corrosion is a process where a refined metal, such as aluminum or iron or alloys such as steel, undergoes degradation. In scientific terms, corrosion is an electrochemical process leading to oxidation of the metal and returning it to its natural state, such as iron being converted to iron oxides.
Electrochemical reactions eat away at the underlying metal substrate, sometimes degrading it to such an extent that it creates aesthetic, mechanical, or structural failures. The economic impact of corrosion is enormous. In a recent report, corrosion was estimated to cost the global economy more than $2.5 trillion annually, or approximately 3.4% of global gross domestic product (GDP).1 Preventing corrosion is clearly an important goal, and paints and coatings play an important role in this never-ending battle. Coatings applied to metal substrates can have a variety of purposes, including the enhancement of aesthetics such as gloss and color, or various functional purposes such as thermal insulation, sound dampening, or antimicrobial properties.
However, in many cases the most important role of a coating on a metal substrate is protection of the metal surface from the environmental effects that lead to corrosion. Waterborne direct-to-metal (DTM) coatings are just one category of coatings designed to protect metal substrates.
We begin by considering the science behind the corrosion process and the methods by which a coating can prevent corrosion. Then we will examine what is meant by direct-to-metal and how the term “DTM coating” is typically discussed in the industry, followed by a description of one-component (1K) DTM coatings based on acrylic latex polymers, which are the most common type of waterborne DTM coatings. We will also discuss principles of formulating waterborne acrylic DTMs for maximum performance over metal substrates.
Finally, we will present a twopart, roundtable Q&A, where industry experts discuss the current trends and technology advances.Note de contenu : - The science of corrosion
