Influence of the Thickening Agents and Some External Parameters to the Formulation on the Viscosimetric Kinetics of the Preimpregnated Polyester
The influence of such thickening agents as CaO; MgO; Ca(OH)2 and Mg(OH)2 on the viscosimetric behaviour of preimpregnated polyester samples (SMC), has been studied. The results of these studies, allow us to conclude that, even though with all the agents the viscosity increases, the MgO is the most effective, as it originates the faster kinetics of viscosimetric increase, compatible with most of the references of transforming through usual moulding. In addition we try to present and discuss some results we have obtained to prove the influence of amount of water and other of the preimpregnated SMC preparation.
