Titre : Multi-angle spectrophotometers for metallic, pearlescent and effect finishes Type de document : texte imprimé Auteurs : V. C. Gupte, Auteur ; P. M. Phadke, Auteur Année de publication : 1998 Article en page(s) : p. 31-38 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Matériau revêtement' 'Peinture métallisée' 'Propriété optique' 'Angle observation' Spectrophotométrie Feuil Index. décimale : 667.9 Revêtements et enduits Résumé : Normal (matte or even glossy) coatings do not exhibit significiant colour change with the change in the viewing angle. Hence, these can be easily assesed using conventional sphere (or 45/0) spectrophotometers. The use of these instruments is widely accepted, and they are routinely used in the Indian paint industry.

Titre : Aqueous polyurethane dispersions : Effect of DMPA and acrylic polyol on dispersion and physical properties of emulsion cast films Type de document : texte imprimé Auteurs : K. G. Raut, Auteur ; S. S. Tanvade, Auteur ; S. R. Srinivasan, Auteur Année de publication : 1998 Article en page(s) : p. 105-109 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Peinture eau' émulsion' Liant 'Uréthanne polymère' Formulation Préparation 'Dimension particule' 'Propriété mécanique' Feuil 'Résistance traction' 'Allongement rupture' 'Relation composition propriété' 'Matériau revêtement' Index. décimale : 667.9 Revêtements et enduits Résumé : The effect of acrylic polyol on properties of emulsion cast films of polyurethane (PU) ionomers has been examined. Isocyanate terminated prepolymers prepared primarily from isophorone diisocyanate (IPDI) and polyoxy propylene glycol (PPG) of MW 1000 were chain extended with trimethylol propane (TMP) and dimethylol propionic acid (DMPA) as potential ionic centers. The urethane forming reaction was carried out in N-methyl-2-pyrollidone (NMP) using dibutyl tin dilaurate (DBTDL) as catalyst. The effects of DMPA and acrylic polyol (AP) on the particle size and its distribution have been studied by automizer. The mechanical properties of the emulsion cast films were determined using Universal tensile tester (Instron). Thermal properties have been studied by using TGA and DSC. It has been observed that the particle size decreased with increase of DMPA content and increased with AP content. Tensile strength decreased, but elongation at break increased with the increase of DMPA content, whereas tensile strength increased and elongation at break decreased with the increase of AP content.

The practical test data of physico-chemical, mechanical and corrosion resistant properties indicate the superiority of uralkyds over alkyds and their proximity to two pack polyurethane coatings. Based on the findings uralkyds could be recommended for protective coating systems where quick air drying, ease of application, better protective properties and low cost are the criteria of the choice of coating system.
