The Effect of Additives on the Curing of an Unsaturated Polyester Resin
Original language description
An exothermic peak, curing time and gel time can describe the curing of unsaturated resin and are used by our method. The method used the cylindrical shape for curing of an UP resin and is based on the standard ISO 584 Plastic/unsaturated polyester resins-Determination of reactivity at 80°C SPI-test. Any kinetic parameters aren´t result of the method.An isophthalic-based polyester resin was used in the experiments. For curing two initiator systems were chosen, each being a mixture of HBO (butanox 50) and BTBCPC (bis(4-t-butyl cyklohexyl) peroxicarbonate). The maximum temperature, curing time and gel time were measured at various initial temperatures in the range from 80°C to 150°C. The the effect of the Low Profile Additive (commercial PVAc additive) and the reinforcement (glass) on the curing were studied. The PVAc content added to the formulation varied betweeen 0 and 50%, according to the experiment. The glass ammount was in the range from 0 to 70%.
