High performance surface tolerant coatings / Mike J. Mitchell in PAINTINDIA, Vol. XLIX, N° 11 (11/1999)
[article]
Titre : High performance surface tolerant coatings Type de document : texte imprimé Auteurs : Mike J. Mitchell, Auteur Année de publication : 1999 Article en page(s) : p. XXVIII-XXXIII Langues : Anglais (eng) Tags : Epoxy Urethane 'Red lead' Petrolatum Index. décimale : 667.9 Revêtements et enduits Résumé : High performance surface tolerant coatings have now been use for over 20 years. This paper reviews the benefits and limitations of these coatings and attempts to give a realistic estimation of expected performance in a range of environments from bridges, coastal refineries and steel plants to offshore maintenance. The evaluation of these materials is described as also the formulation development necessary to give good performance over both rusty hand-prepared steel and intact old coatings.

Langues : Américain (ame) Tags : Chromatographie gel Spectrométrie UV Etude expérimentale Dispersant Traitement surface Titane Oxyde Agent non ionique Adsorption Pigment minéral Interaction Uréthane Epaississant Adjuvant Peinture eau Matériau revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : Size exclusion chromatography in tandem with UV absorbance of the surfactant is used to separate and quantify the amount of nonionic surfactant and model hydrophobically modified ethoxylated urethane (HEUR) thickeners adsorbed on different organic oligomeric polyacid, metal oxide-treated TiO2 surfaces. The isoelectric point imposed on TiO2 by the metal oxide surface treatment determines the amount of organic dispersant adsorbed. The size of the a-olefin on the maleic acid dispersant is also important in the adsorption of the dispersant. The size of the a-olefin on the organic acid dispersant, in turn, determines the amount of surfactant and HEUR thickener adsorbed. The surfactant, unlike the HEUR thickener, exhibits a dependence on the metal oxide treatment in neutral media, independent in several aspects of the amount of organic dispersant adsorbed. The adsorption dependence of HEUR thickeners and nonionic surfactant on the hydrophobe size of the HEUR is discussed.

Titre : New high- throughput screening tool for the evaluation of pigmented UV-A curable coatings- : A case study using low energy lamps Type de document : texte imprimé Auteurs : Stephanie Strazisar, Auteur ; Margaret Kendi, Auteur ; Thomas Fäcke, Auteur ; Leoné Hermans-Blackburn, Auteur ; Xudong Sharon Feng, Auteur Année de publication : 2006 Article en page(s) : p. 307-312 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Marquage fluorescent' 'Criblage haut débit' Photoamorceur Cinétique Copolymérisation Photochimie 'Copolymère uréthane acrylate' Index. décimale : 667.9 Revêtements et enduits Résumé : Pigmented UV radiation-curable coatings have been a challenge to the coatings formulator for a long time. A critical match of pigment and photoinitiator package is crucial for good cure. Another issue facing the coatings chemist is the popularity of low energy lamps, which offer ease of handling, reduced safety concerns, and a low price tag. Obviously, the combination of curing pigmented coatings and using low energy lamps poses a special challenge. To improve the pigmented coating development cycle, a rapid workflow was needed to screen formulations for cure under low energy UV-A radiation. For these types of applications, a high-throughput screening assay for discovering desirable photoinitiator packages was developed. Fluorescent dye-doped coatings cured under UV-A radiation were extracted with solvent. The relative degree-of-cure of the film was determined to be inversely related to a combination of the absorbance and fluorescence of the extractant. When this assay is used in conjunction with automated liquid handling and a spectrophotometer with an x-y scanning stage, the coatings formulator can analyze a large variable set in a short period of time. A primary screening of photoinitiators using this workflow suggests Lucirin® TPO-L, Darocur® 4265, and Irgacure® 2100 as optimum choices.

Nichols, Auteur ; K. Henderson, Auteur ; Markus Mechtel, Auteur ; Thomas Klimmasch, Auteur ; Torsten Pohl, Auteur Année de publication : 2010 Article en page(s) : p. 159-166 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Peinture automobile' Clearcoat Uréthane 'Résistance éraflure' 'Nano-éraflure' 'Macro-éraflure' Guérison Index. décimale : 667.9 Revêtements et enduits Résumé : The scratch and scratch recovery characteristics of two clearcoats, a polyurethane and an acrylic/melamine/silane clearcoat, were measured by a variety of methods. On most size scales tested, the polyurethane possessed superior scratch and mar resistance. The polyurethane also possessed improved scratch recovery after warming for 2 h at 60°C. After 2000 h of accelerated weathering, the scratch recovery characteristics of the polyurethane were largely maintained, while the acrylic/melamine/silane showed a significant drop in scratch recovery performance. Performance of both coatings was related to T g, hardness, and crosslink density.

Titre : The effects of neutralizing bases on the water sensitivity of HEURASE rheology modifiers and their performance in low VOC paints Type de document : texte imprimé Auteurs : Greg D. Shay, Auteur ; J. L. Stallings, Auteur ; P. J.-M. Manus, Auteur Année de publication : 1997 Article en page(s) : p. 285-293 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Peinture eau' Adjuvant Epaississant 'Propriété rhéologique' 'Composé hydrophobe' Uréthane Ethoxylate Sorption 'Vapeur d'eau' Neutralisation 'Base chimique' Index. décimale : 667.9 Revêtements et enduits Résumé : Thickeners and rheology modifiers (TRMs collectivity) are necessary ingredients in nearly all architectural and industrial water-borne coatings formulations. The majority of these coatings additives are organic polymers of either the associative or the non-associative variety depending on the primary mode of thickening. As such, they are film-formers to varying degrees and technically could be considered part of the binder system in a coating. When they are viewed in this capacity, they comprise a minor though important fraction of the total binder in a typical paint formulation.
Based on a recent survey of some 250 architectural interior and exterior coating formulas obtained from supplier literature, the average concentration of TRMs on an active weight basis was approximately 2,5% on latex binder solids. Though the amount is relatively small, most of these TRMs are inherently water soluble and considerably lower in molecular weight than the most latex binders, and because of this, these TRMs tend to impart some degree of water sensitivity to the coating formulations in which they are incorporated. Among the properties that may be affected are scrub resistance, wet adhesion, blister resistance and corrosion resistance.Note de contenu : - HEURASE TRMs
