5. Film formation of latex in dry coating films
University essay from Fakulteten för teknik- och naturvetenskapAbstract : The objective of this master thesis was to investigate the possibility to measure the gain in stiffness of the dry coating due to film formation of latex with a Dynamic Mechanic Thermal Analyzer (DMTA). This could tell when and to which extent the latex forms a film after the drying process. READ MORE
