Název v původním jazyce

Catalytic effects of transition metals in the form of the salts of organic acids in the cross-linking of alkyds

Popis výsledku v původním jazyce

The driers of Co-octoate, Mn-octoate with an active organic ligand, and mixed drier containing the salts of Mn, Ca, and Zn were employed in the cross linking reactions of alkyds. The study verified the possibility of using manganese as an active cation in catalytic curing reactions. The course of the cross-linking of alkyds was monitored on a model system of the reactions of drier with ethyl linoleate, using FTIR spectroscopy. Reaction-rate constants corresponding to the first phase of cross linking were obtained. The final phase of the cross linking reactions was monitored by means of measurement the hardness of the created alkyd film depending on time. The highest efficiency was found with Co-octoate resulting in the development of the highest hardness of coatings. Mn-octoate and mixed driers show a steeper increase in film hardness than Co-drier, yet the final films are suppler.
