Colour predictions in particulate matter from size and refractive index of particles / H. S. Shah in PAINTINDIA, Vol. L, N° 4 (04/2000)
[article]
Titre : Colour predictions in particulate matter from size and refractive index of particles Type de document : texte imprimé Auteurs : H. S. Shah, Auteur ; M. S. Roy, Auteur Année de publication : 2000 Article en page(s) : p. 43-52 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Etude théorique' Colorimétrie 'Indice réfraction' 'Dimension particule' 'Réflexion diffuse' expérimentale' Poudre 'Mélange binaire' ternaire' Pigment Index. décimale : 667.9 Revêtements et enduits Résumé : A theoretical relation correlating particle size and refractive index with diffuse reflectance of particulate system is proposed. Fundamental optical and morphological parameters of particulate systems are determined. Colourimetric curves of seven single component and fifteen binary/ternary mixtures are experimentally measured and compared with predicted curves determined using proposed relation. Overall performance evaluation of the theoretical formulation is made by determining colour difference between measured and calculated curves. Results show that the proposed method satisfactorily work to assess the colourimetric curves of particulate matter. The theoretical technique will be useful to study the colour change due to variation in size in pigment dispersions or chemical powders.

It is highly resistant to a wide range of solvents (including water), has a low coefficient of friction and low cured film refractive index. It has excellent thermal, oxidative and UV stability, resists yellowing and is suitable for high speed application. Markets for this coating include electronics, fibre optic telecommunications and military applications.
