Titre : Formulating with polyurethane dispersions Type de document : texte imprimé Auteurs : Ibrahim Bechara, Auteur Année de publication : 1998 Article en page(s) : p. 236-243 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Polyurethane dispersion films are inherently more sensitive to moisture, however, when crosslinked they are an effective substitute for the solvent-based urethanes. Different crosslinkers, their activation temperatures, typical crosslinking mechanisms and advantages of these resins as grinding vehicles and paint extenders for both organic and inorganic pigments are shown. Also discussed is their formulation with a variety of other water-borne resins and with different crosslinkers to optimize their properties. Examples of different formulations and their properties both clear and pigmented are shown. Note de contenu : - Chemistry of PUDs

Titre : Polyisocyanates today and tomorrow Type de document : texte imprimé Auteurs : Andreas Wenning, Auteur ; Jorn-Volker Weib, Auteur ; Werner Grenda, Auteur Année de publication : 1998 Article en page(s) : p. 244-249 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : For more than 25 years polyurethane powder coatings have enjoyed a strong global presence in the powder coating industry. The article presents the development and chemistry of polyurethane powder coatings comprising the basic structure of the polyisocyanate crosslinkers. The recently achieved improvements in reactivity and performance of isophorone diisocyanate based crosslinkers, which contain no blocking agent and are emission-free, are discussed. New, future-oriented perspectives on obtaining mat surfaces by means of uretdione chemistry are indicated. Note de contenu : - The powder coating market
- Externally blocked polyisocyanates as crosslinkers for polyurethane powder coatings
- Internally blocked polyisocyanates as crooslinkers for polyurethane powder coatings
- New applications of polyuretdione crosslinkersEn ligne : https://drive.google.com/file/d/13ZyEf-6r5SW52dQVsnXh0Ar4WnXYlS9I/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11092

Titre : Colloid Chemistry, Part XI : interfacial and heterogeneous coating structures Type de document : texte imprimé Auteurs : Vladimir V. Verkholantsev, Auteur Année de publication : 1998 Article en page(s) : p. 256-263 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Heterogeneous structures are very common in coatings. Majority of coatings are multicoat systems, built up with a few layers of different materials even comprising a greater number of open, as well as locked and developed interfaces. Typically decorative, protective and special coatings are based on homogeneous polymer matrixes, however the use of heterogeneous polymer matrixes (polymer/polymer composites) for industrial coatings is expanding. Coatings filled with pigments and extenders are essentially heterogeneous and possess many features of composites. Note de contenu : - macro-heterogeneous coating structures
- Adhesion : Coating adhesion - Intercoat adhesion
- Phase modification : Properties inherent to heterophase structures - Pigments and extenders as phase modifiers - Phase modification mechanisms - Filling level - May we consider pigmented coatings composites ? - Minor phase modifiers
- Heterogeneous binder structures : Nonhomogeneous-in-layer and gradiental coatings - Self-stratifying coatings - Multicolor paints
- Organic polymer/inorganic binder combinations : Silicate paints, polymer-ceramics and polymer-cements - Metal-filled coatingsEn ligne : https://drive.google.com/file/d/1s9UeaSZyqS2BHRIOyktzHEDlrixQPeLy/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11093

Titre : Theoretical studies of light scattering power Type de document : texte imprimé Auteurs : N. C. Debnath, Auteur ; D. D. Kotkar, Auteur Année de publication : 1998 Article en page(s) : P. 264-269 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The theoretical light scattering efficiency of commonly used white pigments, extenders and microvoids dispersed in a polymer film has been computed at λ = 5500 Ã… as a function of particle or void size. Either Mie or Aden Kerker's theory has been used for computation depending upon the geometry of scattering particles. The utility of these results for selection and optimum utilization of different scattering materials for paint formulations is discussed. Finally the effect of PVC on the opacity of rutile based paints is discussed in the framework of modified Stieg's model for hiding power based on the dependent scattering theory of Fitzwater. Note de contenu : - Computation of scattering efficiencies of white pigments and extenders : Effect of particle size and refractive index - Effect of the wavelength variation - Relative intensity of scattered light
- Computation of light scattering efficiency of coated rutiles and microvoid disperses in alkyd medium
- Effect of pigment volume concentration and the hiding models for pigmented film
