Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Dispersant - Dispersing agents play a crucial role in adding pigments to lacquers and paints.These products wet the surfaces of the pigment particles and prevent agglomeration and sedimentation. As pigments have evolved new dispersing agents have been developed. Their pigment wetting properties become particularly important with aqueous systems and lessons learned from detergents can help in designing new dispersing agents.

Green issues / Rainer Höfer in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 196, N° 4504 (09/2006)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 196, N° 4504 (09/2006) . - p. 46-47 Titre : Green issues Type de document : texte imprimé Auteurs : Rainer Höfer, Auteur ; Simon Poulton, Auteur ; Uwe Held, Auteur ; Thorsten Roloff, Auteur ; Andreas Willing, Auteur Année de publication : 2006 Article en page(s) : p. 46-47 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Biosurfactants Dispersions et suspensions Polymères en émulsion Surfactants -- Biodégradation Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The author report on a new generation of 'green' surfactants for use in emulsion polymers and polymer dispersions. Newt yers (2007) will mark important anniversaries for a number of key events in the history of the idea of sustainability: it will be 20 years since the publication of the Brundtland report ('Our common future'); 15 years since the Earth Summit in Rio and 10 years since the Kyoto Protocol was signed - all events which have had a significant effect on global public opinion. Neither business nor individuals can afford to ignore environmental issues any longer. The sustainability trend is driven by society's changing values, with consumers demanding that industry acts more reponsability and governments around the world introducing increasingly strict legislation to ensure it does so. International paint and coatings manufacturers are among the companies that have to comply with stricter environmental regulations, while at the same time improving product performance and meeting the requirements of consumers. Unfortunately, the environmentally friendly solutions, which could help them achieve this, are often suspected of veing less effective in terms of performance and cost - a major concern when it comes to surfactants, as the reliability and performance of these substances is essential. However, Cognis' new generation of environmentally friendly surfactants firmly refutes this prejudice. The surfactant system Disponil AFX is an example of how an environmentally conscious approach can bring market success when it does not have an adverse effect on product performance. The product range recently received official recognition from the Federation of German Industries (BDI), in the shape of the organisation's Environment Award. Note de contenu : - Regulatory compliance - the key challenge for surfactants - Disponil AFX: anticipating tighter regulations - High-performance emulsion polymerisation Profitability and environmental concern - two sides of the same coin - A sustainability-based approach Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27527 [article]

Oleochemical polyols - a new raw material source for polyurethane coatings and floorings / Rainer Höfer in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 69, N° 869 (06/1997)

[article]  inJOURNAL OF COATINGS TECHNOLOGY (JCT) > Vol. 69, N° 869 (06/1997) . - p. 65-72 Titre : Oleochemical polyols - a new raw material source for polyurethane coatings and floorings Type de document : texte imprimé Auteurs : Rainer Höfer, Auteur ; Peter Daute, Auteur ; Roland Grützmacher, Auteur ; Alfred Westfechtel, Auteur Année de publication : 1997 Article en page(s) : p. 65-72 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Huiles et graisses Huiles et graisses végétales Liants Matières premières Polyols Polyuréthanes Revêtements Revêtements de sols Index. décimale : 667.9 Revêtements et enduits Résumé : The efforts of both industrialized and developing countries to use and cultivate natural oils as a renewable source for food and foodstuff manufacture have led to a high growth in worldwide production of natural oils. These efforts have also led to an expansion of natural oils as a convenient raw material base for industrial applications. To use natural oils as raw materials for polyurethane production, multiple hydroxyl functionality is required. Hydroxyl functionality occurs naturally in castor oil and can be introduced synthetically in other natural oils with unsaturated sites by epoxidation followed by ring opening. Ring opening can be accomplished by reaction with alcohols, amino alcohols, or acids. Hydroxyl functionality can also be obtained by esterification or transesterification with excess polyol. Dimerization of oleic alcohol, or, alternatively, hydrogenation of dimer acids yields dimer diols, liquid C36 hydrocarbons with two primary OH-groups. The main fields of application of these novel oleochemical polyols are areas where hydrophobicity, hardness, flexibility, and mechanical and chemical resistivity are needed. Applications for oleochemical polyols in VOC-free, two-component polyurethane coatings and floorings, as well as in oven-drying or air-drying aqueous polyurethane dispersions are described. Note de contenu : - OLEOCHEMICAL POLYOLS : Hydroxy functional natural oils - Hydroxy functional fatty acid derivatives - Aliphatic oleochemical diols - EXPERIMENTAL : Materials - Methods - Reaction of hydroxy functional natural oils with MDI - Chemical stability of hydroxy functional fatty acid derivatives - APPLICATION EXAMPLES : Aqueous polyurethane dispersions - Two-component PUR casting applications Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18260 [article]
