Waterborne epoxies / Vladimir V. Verkholantsev in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/96 (05/1996)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/96 (05/1996) . - p. 286-293 Titre : Waterborne epoxies : Self-emulsifying routes to modification Type de document : texte imprimé Auteurs : Vladimir V. Verkholantsev, Auteur Année de publication : 1996 Article en page(s) : p. 286-293 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Additifs Emulsifiants Epoxydes Formulation (Génie chimique) Revêtements en phase aqueuse:Peinture en phase aqueuse Index. décimale : 667.9 Revêtements et enduits Résumé : Compositions suitable for self-emulsifying technology (liquid epoxy resin + water-soluble amine-type hardener) of 2-part ambient cured waterborne epoxy paints and their possible modification to achieve better application and service properties are discussed. Framework for such a modification, which particularly employs the blending of different grades of epoxy resins and water-soluble hardeners, introduction of polymer modifiers and functional additives, is analyzed in terms of colloid behavior of these paints, focusing on the main steps of self-emulsifying technology : resin/hardener co-emulsification, induction period, in-pot life and film-forming process.

Waterborne acrylic barrier coatings / Stephen G. Yeates in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/96 (05/1996)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/96 (05/1996) . - p. 294-298 Titre : Waterborne acrylic barrier coatings Type de document : texte imprimé Auteurs : Stephen G. Yeates, Auteur ; H. Passier, Auteur ; R. Satguru, Auteur ; J. Farrar, Auteur Année de publication : 1996 Article en page(s) : p. 294-298 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Environmental considerations are clearly influencing current decision making concerning barrier technology and will continue to do so in the future. Concerns around recyclability, energy conservation and air-pollution are leading to a reassessment of available barrier technologies. Against this background Zeneca Resins have been actively researching the area of moisture/water barrier coatings, which has led to the launch of a range of water based acrylic barrier coating resins (NeoCryl). This paper describes some of the fundamental work undertaken in understanding the mechanism of liquid-water and moisture vapour diffusion through an acrylic based coating. Some of the design parameters involved in developing hydrophobic acrylic copolymers are discussed, as well as the role crystalline-wax modification has to play. Wax modification is described in terms of a simple stratification model and results from Atomic Force Microscopy (AFM) and Dynamic Contact Angle Analysis (DCAA) are presented.

Additives for water borne coatings / Robert D. Athey in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/96 (05/1996)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/96 (05/1996) . - p. 299-304 Titre : Additives for water borne coatings : Part 2: Fillers, pigments and reinforcing agents Type de document : texte imprimé Auteurs : Robert D. Athey, Auteur Année de publication : 1996 Article en page(s) : p. 299-304 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : There are solid particles added to latex formulations for a variety of reasons. Each of the types of solid particles has their own need for analysis and testing. These solid particles have a variety of effects on the formulation, both in the fluid state and in the final dry film. There are also several classes of these solid particles. We shall discuss the analysis/testing needs, the effects to be expected upon addition of the particles, and the particle classes, as separate sections.

Radiation curing : Health, safety and environment aspects / Philippe Chatton in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/96 (05/1996)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/96 (05/1996) . - p. 307-309 Titre : Radiation curing : Health, safety and environment aspects Type de document : texte imprimé Auteurs : Philippe Chatton, Auteur Année de publication : 1996 Article en page(s) : p. 307-309 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Health and environmental issues do not only affect the competitiveness of the chemical industry in Europe, but also restrict the free trade of products and technologies due to the lack of harmonisation of legislation around the world. The paper covers European (EU) regulatory aspects relevant to RadCure products, such as the implementation of the 7th Amendment of Council Directive 67/548/EEC (Existing Chemicals Programme, Risk Assessment Directive, OECD polymer definition,...) and current regulatory developments (further extension of EC Directive 90/128 governing food contract applications, environmental labelling). The paper will also describe the strategy developed by European chemical suppliers within the RadTech association to comply with EU Directives. Emphasis will be put on topics which should be addressed globally and for which global harmonisation should be sought. This is a key step for the global introduction of new products and technologies at an acceptable cost, which is essential for the long-term sustainability of the RadCure and coating industries. Note de contenu : - Why all these challenges ? - Need for standardization and global harmonization - Risk assessment - Legislative framework in the EU / chemicals regulations - European volatile organic compound (VOC) council directive - Extension of the EC food contact directive to coatings and varnishes Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11292 [article]
