Polymeric surfactants and their application in polymerisation and in coatings / A. Bouvy in PAINTINDIA, Vol. XLVI, N° 8 (08/1996)
[article]
Titre : Polymeric surfactants and their application in polymerisation and in coatings Type de document : texte imprimé Auteurs : A. Bouvy, Auteur Année de publication : 1996 Article en page(s) : p. 29-34 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture Adjuvant 'Agent surface' Polymère 'Alkyde résine' Emulsification Dispersant 'Effet stérique' Polymérisation 'Article synthèse' Index. décimale : 667.9 Revêtements et enduits Résumé : In recent years, there has been considerable interest in polymeric surfactants. EO/PO copolymers can be considered to be polymeric surfactants. Polyacrylic acid of low specular weight (<15.000), condensates of naphtalene sulphonate with formaldehyde and sulfonated styrene/maleic anhydride copolymers are often also included in descriptions of polymerics surfactants. The word polymeric suggests high molecular weight but there is no real justification for calling these materials as such. Although the term olipgomeric would be more appropriate, the word polymeric has now been firmly established. Note de contenu : STRUCTURE OF POLYMERIC SURFACTANTS

Revêtements en phase aqueuse:Peinture en phase aqueuseTags : 'Peinture phase aqueuse' Formulation Pigment Mouillage Dispersion Floculation Défloculation 'Répulsion électrostatique' 'Encombrement stérique' Index. décimale : 667.9 Revêtements et enduits Résumé : Environmentally friendly coatings pose multiple technological and cost-containment challenges. As a result, new wetting and dispersing technologies which simultaneously enhance performance and reduce costs have gained in importance. An in-depth discussion of the above crucial issues will be presented. Key words are : wetting vs. dispersing, deflocculation, controlled flocculation, reengineering, pigment concentrates, usage levels, points of addition, formulation hints. New, multifunctional polymeric additives for resin-free pigment concentrates and new additive structures to enhance performance in aqueous and high solids systems will also be presented. Note de contenu : - Wetting versus dispersing : What's the difference ? - The wetting phenomenon; distinctive features - The dispersing phenomenon : distinctive features - Electrostatic repulsion - Steric hindrance
- Deflocculation: how and why ?
- Controlled flocculation: how and why ? - Special considerations in aqueous systems - Pigment charge
- The reengineering of wetting and dispersing
- Less cost and more performance - Pigments - Grinding resins - Solvents - Additives
- Usage levels, points of addition, and practical formulaion hints - Determining the appropriate usage level : initial considerations - Point of addition/order of addition - Single grinds and co-grinds - Rheological additive combinations - The possible side-effects of wetting and dispersing additivesPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11384
