Langues : Anglais (eng) Tags : 'Industrie  peinture  vernis'  Biotechnologie  Microorganisme  'Epuration  eau  usée'  'Eau  usée  industrielle'  biologique'  'Déchet  industriel'  'Traitement  déchets'  Adjuvant  Antisalissure Index. décimale : 667.9 Revêtements et enduits Résumé : In the paint industry, the general emphasis has been on the control of micro-organisms due to their deleterious effects on both raw materials as well as the finished product. However increasingly, research is being conducted to discover ways of exploiting micro-organisms in a positive way. Thus the ability of micro-organisms to tolerate and degrade unwanted, waste products that are often toxic to the environment, is made use ofin biofiltration plants for VOC reduction and emission control. Effluent treatment plants use the same principle to reduce levels of wastes to acceptable standards. Micro-organisms are also capable of synthesizing useful products which may find use as raw materials in the paint field. Thus the production of antifouling agents, industrial polysaccharides, pigments, etc. by micro-organisms offer eco-friendly and cheaper alternatives to chemically produced products without any compromise on the quality of the final product. Moreover the ability to manipulate micro-organisms through genetic engineering opens the road to a host of possibilities in the future, making microbial biotechnology an exciting and interesting field of research.

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.
