Unsaturated polyester resin is a chemical used as a polymer. This type of resin is saturated because its polymer chains are not saturated. This type of resin in the polymer state is generally stored in liquid form in containers and is used to produce plastic parts or various industries.
Exothermic peak
When the cobalt catalyst is added to the resin, chemical reactions occur that result in the resin changing from a liquid to a solid state. This process is known as exothermic peak, which is accompanied by an increase in temperature and heat production. As the temperature increases, the chemical reactions run faster and the resin forms as a solid.

During the curing process of unsaturated polyester resin, a higher temperature is recorded as an exothermic peak. This temperature indicates the maximum temperature that the resin can withstand to become a solid state. This process increases the strength and hardness of manufactured parts, which are especially used in the automotive, packaging and construction industries.
Unsaturated polyester resin is widely used in the production of various plastic products due to its special features such as formability and flexibility. Since unsaturated polyester resin can be easily produced and processed, this type of resin is known as one of the important basic materials in the plastic industry and is used in the production of various consumer products.
Chemical properties of resin
Chemical properties of resin include heat resistance properties, mechanical properties such as bending and stretching resistance, and electrical properties including electrical insulation. The peak exotherm is also known as an important temperature for resin curing where the resin is fully cured and begins to form crosslinks. At this temperature, the curing and processing of the resin is done completely.
