Titre : Chitosan-hybridized acrylic resins prepared in emulsion polymerizations and their application as interior finishing coatings Type de document : texte imprimé Auteurs : Tamaki Wada, Auteur ; Yasuhiro Matoba, Auteur ; Tadashi Uragami, Auteur Année de publication : 2005 Article en page(s) : p. 577-582 Note générale : Bibliogr.

Chitosan-hybridized acrylic emulsions were prepared by two methods. To produce stable chitosan-hybridized acrylic emulsions, the pre-emulsion dropping method is superior to the monomer dropping method. The adsorption performances for formaldehyde in chitosan-hybridized acrylic resin films increased with increasing chitosan contents; the films also had adsorption abilities for hydrogen sulfide and ammonia. Tensile strengths and elongation at breaking points decreased with increasing chitosan contents. Interior finishing coatings made from chitosan-hybridized acrylic resin emulsions have the qualities necessary for an interior finishing coating and showed excellent adsorption abilities for formaldehyde.

Titre : Effect of particle size distribution on the performance of two-component water-reducible acrylic polyurethane coatings using tertiary polyisocyanate crosslinkers Type de document : texte imprimé Auteurs : Denise E.

This paper discussed an experimental study to develop a two-component water-reducible polyurethane coating using a tertiary aliphatic polyisocyanete crosslinker with dry times, appearance, and reactivity equivalent to a two-component solventborne system. The effects of acrylic polyol monomer composition, glass transition temperature (Tg), and hydroxyl concentration on drytime and ambient cure film performance have been determined. The effects of particle size distribution of the formulated coating on performance were examined. It was found that smaller particle size provides overall improved film propertics, i.e., jaster dry time, increased hardness, and faster development of solvent resistance. The relationship of both acrylic polyol composition and formulation variables on the particle size distribution are discussed.

Titre : Evaluation of alkane sulfonic acid catalysts and derivatives for curing activity in a melamine/acrylic polyol coating formulation using Fourier transform infrared spectroscopy Type de document : texte imprimé Auteurs : Dana Garcia, Auteur ; Stanley I. Sandler, Auteur ; Joseph Brennan, Auteur ; Olivier Bousquet, Auteur Année de publication : 2000 Article en page(s) : p. 89-93 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture Mélamine résine Acrylique dérivé polymère Durcissement Réticulation Acide alcanesulfonique Spectrométrie IR Transformation Fourier Etude expérimentale Index. décimale : 667.9 Revêtements et enduits Résumé : FTIR measurements may be able to replace more laborious physical property determinations and thus serve as an efficient screening methodology in catalysis driven processes. This possibility was considered in evaluating alkane sulfonic acids catalyst performance to promote the cure of a melamine resin with acrylic polyols. The example chosen here is an evaluation of alkane sulfonic acid derivatives to measure catalytic efficiency of the cure reaction between hexamethoxymethylmelamine (HMMM) and an acrylic polyol. The IR measurements provided information on the extent of reaction, via monitoring the disappearance of the OH stretching mode at 3472 cm-1 associated with the acrylic polyol. This method may also be used to provide detailed information on reaction kinetics and insight into the cure mechanism. As the reaction proceeds, the coating's properties change and IR measurements can serve as a probe for these changes.

Titre : Mechanism for environmental etch of acrylic melamine - based automotive clearcoats : identification of degredation Type de document : texte imprimé Auteurs : P. J. Schmitz, Auteur ; Joseph W. Holubka, Auteur ; Li - Feng Xu, Auteur Année de publication : 2000 Article en page(s) : p. 39-45 Note générale : Bibliogr. Langues : Américain (ame) Tags : Industrie automobile Matériau revêtement Vernis Mélamine résine Acrylique dérivé polymère Feuil Dégradation chimique Hydrolyse Pluie acide Mécanisme réaction Produit Etude expérimentale Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : This paper focuses on defining the reaction mechanism involved in the environmental etch of acrylic melaminic-based automative clearcoats via an identification of reaction products. This has been accomplished through a comparative study of products formed on acid treatment of neat crosslinkers, and those formed following laboratory acid treatment and field exposure of acrylic melamine clearcoat systems. Bulk elemental, X-ray photoelectron spectroscopy (XPS), and infrared (IR) analyses of sulfuric acid-treated melamine crossllinkers show that acid hydrolysis results primarily in the formation of melamine sulfate. Melamine sulfate formation was also observed following laboratory and field exposure of acrylic melamine clearcoat systems. These results confirm that the primary mode of melamine crosslink decomposition is through hydrolysis of acetal linkages and subsequent formation of melamine sulfate. However, data show that hydrolysis of pendent amino groups on the triazine ring also occurs. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5805

Briscoe, Auteur ; S. G. Yeates, Auteur ; J. N. Hay, Auteur ; Joseph L. Keddie, Auteur Année de publication : 2001 Article en page(s) : p. 65-73 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture poudre Propriété mécanique Feuil Structure surface Thermodurcissable Acrylique dérivé polymère Résistance rayure Vernis Dureté Microdureté Module élasticité Topographie Etude expérimentale Index. décimale : 667.9 Revêtements et enduits Résumé : Both nano-scratching and nano-indentation techniques have been used to evaluated the mechanical properties of the surface of acrylic coatings, with and without added pigment. The coatings were formed from thermosetting, acrylic powders. Both types of coatings-clear and pigmented-do not exhibit any significant differences in their hardness with an increase in baking time from 7 to 15 min. According to the scratching profiles, the deformation induced at the surface is virtually elastic. Introducing the pigment causes a slight increase in the elastic modulus but not significant variation in hardness. In all coatings, the computed hardness and the elastic modulus vaues are higher near the surface (perhaps as a result of tip geometry effects), but these readily reach plateau values that are consistent with other work available in the literature. A long-range surface profiler, which provided two-dimensional and three-dimensional topographical maps of the coatings surfaces, reveals undulations in the surface with a wavelength on the order of 2-4 mm. Moreover, the topography of the pigmented coating is significantly smoother than that of the clear coating in which shallow pits (about 100 µm in diameter) are randomly distributed at the surface. The nano-mechanical properties within these pits are similar to the bulk of the coating. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5688
