Titre : Basic concept of paint technology and interaction parameters Type de document : texte imprimé Auteurs : K. V. S. N. Raju, Auteur ; M. Yaseen, Auteur Année de publication : 1996 Article en page(s) : p.19-24 Langues : Anglais (eng) Tags : Peinture Liant Solvant Pigment 'Matière charge' Adjuvant 'Concentration pigmentaire volumique critique' Index. décimale : 667.9 Revêtements et enduits Résumé : The growing organic materials production potential calls for the industry to take several factors into consideration while diesigning a paint formulation. It i essential to charcterise it carefully before the coating formulation becomes commercial product. The majority of paint formulations are composed of components like pigments, resins, solvents, and additives. The knowledge abut their interaction parameters among the components of the paint formulation is very essential to access their compatibility . The sdesign of an organic coatig/paint formulation requires the understanding and establishing the phenomena involved from the stage of its preparation to the stage of it being used in actual service. In recent years, the physico-chemical properties of individual components and their intercation parameters are being examined more critically before a paint is formulated. This practice requires data on interaction and other physical parameters of the main components of the paint formulation. The information provided here on various aspects of raw materials and about their interaction parameters may help in designing paint formulations. This also provides information about the effect of internal and external physico- chemical parameters on the properties of coatings in service.

Titre : Role of micaceous iron oxide in protective coatings Type de document : texte imprimé Auteurs : Chinmaya Nayak, Auteur Année de publication : 2002 Article en page(s) : p. 52-72 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Résistance intempérie' Feuil 'Perméabilité eau' 'Propriété physique' Délaminage Cloquage Liant 'Forme particule' 'Concentration pigmentaire volumique critique' volumique' Performance 'Structure lamellaire' Fer Oxyde 'Protection corrosion' 'Pigment anticorrosion' minéral' Formulation 'Peinture Matériau Revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : Micaceous iron oxide (MIO) pigments have long been used successfully all over the world in a variety of protective coatings for long term protection of structural steels. The protective characteristics of these pigments have been attributed to the orientation of lamellar and flaky pigments which produces an increase in resistance to water permeation through the paint film. Use of micaceous iron oxide also reduces the ultraviolet degradation of the binder system and provides mechanical reinforcement to the paint film. The present article deals with the physical and chemical characteristics of these pigments and their effects on the final coating performance. Several other factors such as their incorporation level, influence of pigment volume concentrations, compatibility with different binders and extenders have also been discussed. The mechanism, using micaceous iron oxide has also been discussed in detail. Special emphasis has also been focussed on their water permeability and weatherability characteristics. In addition to this the blistering behavior of the pigmented paint film has been explained on the basis of water vapor transmission phenomena.

The nature of the interactions between dyes and surfactants is one of the basic piece of information for understanding the process of dyeing and finishing of textile material. The role of attractive interactions between the hydrocarbon tails and repulsive interactions between the surfactant head groups on the micellar association process have been studied. The presented work is oriented on the determination of the critical micelle concentration and molar conductance, in aqueous solution of cationic surfactant cetyltrimethyl ammonium bromide by using the electric conductivity method. From conductivity data parameters for dyes – surfactant interaction such as micellar ionization degree α, counter ion binding and free energy of micellization have been calculated. On the basis of results it is clear that critical micelle concentration depends on the nature of ionic group and concentration of counter ion in solution.
