SynergieIndex. décimale : 667.9 Revêtements et enduits Résumé : Over the last twenty years the surface coatings industry has undergone dramatic shifts in the direction of formulation work. Demands for increasing performance have certainly always been present, but in the last two decades consideration for the environment and worker safety have become even more important than cost effectiveness. Much of the safety improvements that have been implemented have occured as a direct result of legislation imposed upon the industry.
Historically anti-corrosive coatings relied upon resins which required large quantities of volatile organic solvent and lead or hexavalent chromium pigments. These are no longer acceptable in today's environmentally conscious world. The move towards water-based coatings and away from toxic pigments is already well underway, but the need for improvements is (and always will be) there. Current pigments have approached the performance of lead and chrome pigments, but, as yet, have not surpassed them. In addition, these materials are more complicated to work with than their toxic forbearers.
Meticulous formulation is required to optimize performance of non-toxic corrosion inhibitors. The proper loading level and pigment volume concentration must be obtained. The old adage 'more is better' does not apply to these new pigments. While the research is still underway to find the perfect replacement for leads and chromes, formulators today need techniques which will help them now. It has been found that several of today's non-toxic corrosion inhibitors can work synergistically with each other to give a performance greater than either one alone.Note de contenu : - Early synergisms

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Anticorrosion primers and direct-to-metal (DTM)-coatings are protective coatings with a primary function of protecting against corrosion. A secondary purpose is to maintain the aesthetic aspects and value of expensive good such as cars, trucks and aeroplanes. The cost of corrosion runs to approximately 3-4 % of GDP on an annual basis and therefore has an global economic impact of around US$3.3 billion.

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : 3-Methyl-4-amino-5-mercapto-1,2,4-triazole (MAMT) was synthesized, and its inhibition action on the corrosion of 6061 Al alloy in 0.5 M sodium hydroxide was investigated by means of potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The effect of inhibitor concentration, temperature, and concentration of the corrosion medium on the inhibitor action was investigated. The surface morphology of the metal surface was investigated by scanning electron microscopy (SEM). The inhibition efficiency increased with the increase in the concentration of the inhibitor, but decreased with the increase in temperature. Both thermodynamic and kinetic parameters were calculated and discussed. The adsorption of MAMT on the base alloy was found to be through physisorption, obeying Langmuir’s adsorption isotherm. The results obtained from both the techniques were in good agreement with each other.

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 667.6 Peintures Résumé : Les peintures en poudre thermoplastiques Abcite, fabriquées par Axalta Coating Systems, offrent une protection optimale et extrêmement durable contre la corrosion, pour les structures en acier, aluminium, cuivre autres métaux, même dans les conditions les plus difficiles.

Titre : Accelerated corrosion testing for bisphenol-A non-intent metal packaging resin Type de document : texte imprimé Auteurs : Goliath Beniah, Auteur ; Linqian Feng, Auteur ; Jeffrey Clauson, Auteur ; Abraham Boateng, Auteur ; Hongkun He, Auteur ; Cameron L. Brown, Auteur ; Andrew T. Detwiler, Auteur Année de publication : 2020 Article en page(s) : p. 32-40 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acétique, Acide L'acide acétique (du latin acetum) ou acide éthanoïque est un acide carboxylique de formule chimique : C2H4O2 ou CH3COOH.
L'acide acétique pur est aussi connu sous le nom d'acide acétique glacial. C'est un des plus simples des acides carboxyliques. Son acidité vient de sa capacité à perdre le proton de sa fonction carboxylique, le transformant ainsi en ion acétate CH3COO-. C'est un acide faible.
L'acide acétique pur est un liquide très faiblement conducteur, incolore, inflammable et hygroscopique. Il est naturellement présent dans le vinaigre, il lui donne son goût acide et son odeur piquante (détectable à partir de 1 ppm21).
C'est un antiseptique et un désinfectant.
L'acide acétique est corrosif et ses vapeurs sont irritantes pour le nez et les yeux.
Il doit être manipulé avec soin. Quoi qu'il n'ait pas été jugé cancérigène ou dangereux pour l'environnement, il peut causer des brûlures ainsi que des dommages permanents à la bouche, au nez, à la gorge et aux poumons. À certaines doses et en co-exposition chronique avec un produit cancérigène, son caractère irritant en fait un promoteur tumoral de tumeurs (bénignes et malignes)21. Ceci a été démontré expérimentalement chez le rat.

PolyuréthanesIndex. décimale : 667.9 Revêtements et enduits Résumé : Increasing awareness of environmental, health, and food safety issues, as well as increasing regulations on substances with potential health effects, are major driving forces for consumer behavioral changes. These behavioral changes propel the shift toward development of alternative products free from substances of concern. One such substance is Bisphenol-A (BPA), a chemical commonly found in the protective linings of food or beverage metal cans. BPA has undoubtedly become a major cause of concern, prompting serious examinations from various regulatory bodies across the world connecting BPA to adverse health effects.
Since 2015, France has issued a ban on BPA in all packaging, containers, and utensils intended to come into contact with food.1 As recently as 2018, the European Union published a regulation that further restricts the presence or use of BPA-containing substances in plastic food contact materials. The new regulation reduces the specific migration limit for BPA in varnishes and coatings for food contact applications by an order of magnitude (from 0.6 mg/kg to 0.05 mg/kg) over previous regulations.2,3 Although the U.S. Food and Drug Administration has not issued a complete ban on the use of BPA in food can lining applications, several states such as Maryland, Connecticut, and California have placed further restrictions on its presence in food cans. Given the increasing regulatory pressure, the demand for Bisphenol-A Non-Intent (BPA-NI) metal packaging coatings will continue to increase in years to come.Note de contenu : - Table 1 : Details of white PU formulation
