How long can unsaturated polyester resin be stored for? It is also a very durable form of resin. Unsaturated polyester resin is a thermoset, capable of being cured from a liquid or solid state when subject to the right conditions. However, the rate of curing depends on the temperature of the resin and the activity of the catalyst. Fibers used to reinforce composites are supplied directly by fiber manufacturers and indirectly by converters in a number of different forms, which vary depending on the application.
