| 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. |
