New fast drying styrenated alkyds / P. D. Sathe in PAINTINDIA, Vol. XLIX, N° 5 (05/1999)

[article]  inPAINTINDIA > Vol. XLIX, N° 5 (05/1999) . - p. 43-46 Titre : New fast drying styrenated alkyds Type de document : texte imprimé Auteurs : P. D. Sathe, Auteur ; Bhalchandra B. Gogte, Auteur Année de publication : 1999 Article en page(s) : p. 43-46 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Matériau  revêtement'  Vernis  Liant  'Alkyde  résine'  Formulation  modifié'  Styrène  'Propriété  physique'  mécanique'  chimique'  Feuil Index. décimale : 667.9 Revêtements et enduits Résumé : Some interesting experiments on styrenated alkyds containing 5 to 50% styrene have been conducted. The oil length of alkyds have been varied from 28 to 60%. A special catalyst called styro catalyst has been developed in our laboratory for smooth polymerisation. The proportion of polyol has been drastically reduced. A net saving of 28-30% has been claimed on raw material cost. The physico-chemical properties and film properties of varnish samples have been studied. Some fast drying compositions have been identified. The resistance of film to water, alkali and detergent is good. The resistance to acids is slightly poor. The hardness, adhesion and drying characteristics of many formulations are excellent. A two pack system one containing the binder and other containing the drier has been recommended. The stability of attempted formulations is excellent when used as a two pack system. A wide variation in proportion of oil, styrene and rosin can help to control the raw material cost depending on price fluctuation. These varnishes can be used in formulations of metal primers, wood primers, semigloss enamels, oil bound distempers, printing inks and duplicating inks.

Novel inks from styrenated alkyld resins / P. D. Sathe in PAINTINDIA, Vol. XLIX, N° 7 (07/1999)

[article]  inPAINTINDIA > Vol. XLIX, N° 7 (07/1999) . - p. 77-78 Titre : Novel inks from styrenated alkyld resins Type de document : texte imprimé Auteurs : P. D. Sathe, Auteur ; Bhalchandra B. Gogte, Auteur Année de publication : 1999 Article en page(s) : p. 77-78 Langues : Anglais (eng) Tags : Encre  Liant  '  Alkyde  résine'  'Matériau  modifié'  Styrène  Formulation Index. décimale : 667.9 Revêtements et enduits Résumé : Novel inks could be prepared from styrenated alkyd resins specially prepared to suit the requirement of inks. The characteristics of inks required for various printing processes are different. We have formulated the ink-compound such as Styro Letter Compound for letter press ink, Styro Screen Compound for screen printing and Styro Litho Compound for lithographic printing. The inks prepared from these ink compounds were actually used on respective printing presses. The results are satisfactory.

Primer and enamel compositions based on new type of styrenated alkyds / P. D. Sathe in PAINTINDIA, Vol. XLIX, N° 6 (06/1999)

[article]  inPAINTINDIA > Vol. XLIX, N° 6 (06/1999) . - p.43-50 Titre : Primer and enamel compositions based on new type of styrenated alkyds Type de document : texte imprimé Auteurs : P. D. Sathe, Auteur ; Bhalchandra B. Gogte, Auteur Année de publication : 1999 Article en page(s) : p.43-50 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : A new type of styrened alkyds have been synthetised using substantial proportion of styrene (30 to 50%), a lower percentage of polyols and anhydrides and moderate proportion of oil and rosin. A new catalyst, styrocatalyst has been developed in our laboratory dor this synthesis. Various paint compositions like enamel, metal primer, wood primer and cement primer have been described in a two pack system. These compositions have excellent drying, hardness, durability and gloss characteristics. The resistance of films of these primers and enamels to water, alkali detergent and hydro chloric acid solutions is good to excellent. The resistane to sulphuric acid and nitric acid needs improvement. There is a net saving of 15 to 20 % in raw material cost of these paints.
