Sažetak

The application of thermogravimetric analysis can be very useful in the method since an extensive range of resins is used in founding. The thermal analysis performed for three different binders indicated the similar destruction mechanism.Along with the temperature increase the mass decrease of samples is related to the organic compounds decomposition and proceeds in a similar fashion regardless of the atmosphere in which the process occurs. However, for each of the tested binders,a certain critical temperature exists, above which - in the oxygen presence - the burning process of the majority of organic compounds forming the given substance occurs.
