Titre : Effective cost saving in high performance coating by replacing titanium dioxide with calcium aluminium silicate & magnesium aluminium silicate Type de document : texte imprimé Auteurs : Hitesh Hirani, Auteur ; Ashok Dighe, Auteur ; Chintan Patel, Auteur Année de publication : 2006 Article en page(s) : p. 75-90 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Titanium dioxide is the brightest, whitest pigment available. TiO2 is one of the most widely used pigments in paint, plastics, textiles, cosmetics, and paper industries.' It efficiently scatters visible light thereby imparting whiteness, brightness and opacity to paint and coating material. The cost of TiO2is increasing steadily and thus the cost of paint with minimum operational margin. The partial replacement of the TiO2 Pigment with the use of less expensive subsidiary product will give some cost advantage. In the present scenario high performance coatings are most widely used to preserve industrial equipment, pipelines, plant and buildings from deterioration by exposure to water, chemicals or weather which find application in automotive, industries and industrial structures, iron, steel and concrete structure, ships and marine structures, reactors, pipelines, machinery components etc. The present work emphasises on the partial replacement of TiO2pigment with Calcium Aluminum Silicate (CAS) and Magnesium Aluminum Silicate (MAS) in high performance coating application without affecting the quality of coating. Different performance coatings were prepared with partial replacement of TiO2 with CAS & MAS and analyzed for important optical properties like opacity, whiteness, Gloss and brightness. The mechanical properties were also evaluated for these coatings. The CAS & MAS fillers showed potential of replacing 5 - 30% by weight of TiO2 in different types of performance coatings.

Titre : Vinyl ester resins and their blends for protective Coatings Type de document : texte imprimé Auteurs : Arun Maithani, Auteur ; Deepak Srivastava, Auteur ; Devendra Agarwal, Auteur Année de publication : 2006 Article en page(s) : p. 97-104 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Vinyl ester resins (VER's) of varied acid values (12, 26 and 40 mg/gm solid) were prepared by reacting different monoepoxies (DEGBA, cresyl, phenyl and butyl glycidyl ether) with methacry/ic acid (mole ratio 1:0.9) in the presence of triphenyl phosphene (1 phr by wt. of epoxy resin) as catalyst and hydroquinone (200 ppm) as an inititor at 85 ± 1 °C. The samples of different VER's for curing studies was prepared by using 10/4/0.2 (by wt.) of resin, reactive diluents (Styrene) and benzoyl peroxide respectively. Blends of different VER's of comparable acid values were also cured in the same manner as with the individual VERs. The curing conditions of the experimental coatings were determined by using the Differential Scanning Calorimetry (DSC) system.. The DSC scans were obtained under dynamic and isothermal conditions choose a temperature and time for completion of curing reaction (90 min at 85°C) The coatings of individual VER's and their blends when exposed to different chemicals for a period of one year showed better chemical resistance properties than already available monoepoxy based coating systems. Thermal stability of VER's having lower acid values was better than those of VERs having higher acid values. Cresyl and phenyl based VER's blend showed better mechanical and chemical resistance properties as compared to those synthesized from DEGBA and butyl based VER's blend.
