Polyester resin is a type of synthetic resin that consists of chemical compounds called polyester. This resin is available as a colorless or light yellow liquid and hardens by combining it with a substance called a hardener.
Polyester resin is used in various industries due to its features such as high resistance to impact, corrosion, heat and UV, resistance to chemical agents, light weight and beautiful appearance.
Polyester resin has the ability to form strong, light and resistant parts against chemical and thermal conditions. It is used to make sheets, pipes, car parts and marine parts.
By adding different materials such as color and additives, different properties such as colorability, impact resistance and resistance to certain environmental conditions can be obtained in polyester resin.

Polyester resin is a type of thermal plastic that is made from polyolefin esters. Polyester resin hardens in two ways, which are described below:
In this method, the polyester compound is mixed with a chemical catalyst (for example, benzoyl peroxide) in the presence of heat. This process starts a polymerization reaction in polyester, which results in the formation of a hard surface layer and more resistance for the polyester resin.
In this method, the polyester resin is sweated at high temperature (typically between 60-80°C) and high pressure (typically between 200-300 psi). This process causes polyester molecules to combine together and form a harder surface layer.
In both methods, after hardening, the polyester resin takes on more strength and hardness, which makes it suitable for industrial use.
There are different types of polyester resins, each of which is used for a specific application. Among the types of polyesters, we can refer to fiberglass polyester resin, sculpture, automotive industry, composite parts, molding, sink, etc. The most important of which are as follows.
Polyester resin for sculpture has a liquid and transparent state, which is very resistant in terms of elasticity and flexibility. On the other hand, high penetration and adhesion, resistance to uv rays and also non-absorption of moisture are other features of this polyester resin. For this reason, it is used in making composite parts, sculptures, car parts and layering.
Buying polyester resin for molding has very good flexibility and elasticity. For this reason, they are easily deformed and with the right thickness, they are very suitable and standard for molding.
Polyester resin for sinks have very good resistance to thermal stresses and are antibacterial. On the other hand, their extraordinary mechanical properties make them resistant to sanitary detergents. For this reason, they can be used to make kitchen granite stones and sinks.
The amount of hardener in polyester resin depends on the type of polyester resin and its application. There are different hardeners for polyester resin that are used to make a variety of products with different characteristics.
Usually, in the industry, the amount of hardener used for polyester resin is about 1 to 3% of the total volume of the material used. By increasing the amount of hardener, the hardness and resistance of the polyester resin increases, but this also comes with a decrease in the applicabilitytime and drying time.
For example, to make transparent parts from polyester resin, hardeners of 2-3% are usually used. While for the production of durable and widely used parts with high mechanical properties, the amount of hardener can be up to 4-5%. However, the amount of hardener in each case should be determined based on the instructions of the material manufacturer and the experience of industry experts.
If the polyester resin is not of high quality, they do not have high resistance to sunlight, temperature increase, humidity, etc., and this issue reduces the lifespan of the polyester resin.
On the other hand, considering that resins are used in making molds, industrial parts, etc., their high quality is extremely important. One of the most important features of quality polyester resins is their high hardening speed, high mechanical and thermal resistance, resistance to UV rays, extremely high adhesive properties, and their antibacterial properties.

Polyester resin and epoxy resin are both types of construction resins that are used to produce a variety of industrial and construction products, but there are also differences between them:
Polyester resin is made from polyester filaments that are hardened by isocyanate (such as toluene diisocyanate). While epoxy resin is made of twin epoxies that are hardened by a hardening agent (such as amines).
Compared to polyester resin, epoxy resin has higher hardness, resistance to corrosion, impact, and heat. While polyester resin has flexibility, resistance to sunlight, and higher processability (in cutting and carving).
Epoxy resin is mostly used in coating, bonding, aluminum and steel products, aerospace and aircraft construction, precision instruments, and machinery manufacturing industries. While polyester resin is mostly used in construction industry, shipbuilding industry, boat construction and repair, industrial machinery, and interior decoration.
A substance that helps polyester resin harden quickly and completely is known as a catalyst or catalyzer. This material is usually added in a small percentage to the polyester resin to make the hardening process faster. In industry, two types of catalysts are commonly used for polyester resin:
This catalyst is mostly used to make large parts or similar structures, and as the temperature increases, the rate of hardening of the polyester resin increases.
This catalyst is used to make almost any type of part, including small and thin parts. Here, the catalyst is combined with the polyester resin and the hardener to form a triple system that ultimately gives the desired part enough hardness.
It should be noted that the type of catalyst used depends on the type of polyester resin, the type of hardener and the conditions of the manufacturing process.
Curing time or polyester closing time is the time when the polyester resin is fully hardened and closed. This time can be different depending on the type of polyester resin and hardener used, the temperature and humidity of the environment, the thickness of the part and different environmental conditions.
In general, polyester resin hardens faster than epoxy resin, but its curing time can be from a few minutes to a few hours or even a few days long depending on different environmental conditions. In general, to ensure that the polyester resin has fully cured, you should wait at least 24 to 48 hours after applying it in a cool, dry environment.
Polyester resins are usually obtained by combining different raw materials and must be cured in order to harden them. The baking method and the required temperature are different depending on the type of polyester resin and the type of hardener used, and it is better to follow the instructions for each type of polyester resin.
But in general, the following steps can be followed for baking polyester resin:
The temperature and curing time may vary depending on the type of polyester resin and hardener used, the thickness of the part and different environmental conditions. It is better to read the instructions for each type of polyester resin and do the baking according to the environmental conditions and the available equipment.
