Introduction and application of epoxy curing agent

Epoxy curing agent is a common chemical that is usually used to chemically react with epoxy resins to form solid materials with high strength, high heat resistance, and high corrosion resistance.

Epoxy resin itself is a thermosetting polymer material with good electrical insulation, adhesion and chemical stability, which is widely used in electronic and electrical, construction, machinery, aerospace and other fields.

However, the curing agent must be added to the epoxy resin when it is used, and the curing reaction is carried out under certain conditions to generate a product with a three-dimensional network structure, in order to show excellent performance and become an epoxy material with real use value.

Classification of epoxy curing agents

Epoxy curing agent can be divided into alkaline epoxy curing agent and acidic epoxy curing agent according to their chemical structure.

According to the curing mechanism, it can be divided into additive forming epoxy curing agent and catalytic epoxy curing agent.

Among them, latent curing agent has been the focus of research in recent years. The single-component system composed of curing agent and epoxy resin has certain storage stability at room temperature.

Under the conditions of light, moisture, heating and pressure, the curing reaction can be carried out quickly.

Main uses of cyclic hydrogen curing agent

Architecture and Civil Engineering:

Epoxy curing agents are often used to repair damaged concrete structures, such as Bridges, tunnels and underground pipelines, which can increase the hardness and compressive properties of concrete, prevent water penetration and chemical erosion. In addition, it is also used in floor coatings and waterproof coatings.

Paints and Coatings:

In household and industrial coatings, such as weather-resistant coatings, automotive paints and Marine coatings, epoxy hardeners can increase the hardness and gloss of the coating to prevent color change and corrosion. It is also used for printing inks and graphable surfaces such as whiteboards and magnetic coatings.

Electronics and Appliances:

In the electronics industry, epoxy assimilators are used to encapsulate semiconductor devices, circuit boards and cables, etc., to improve the impact resistance and water resistance of these devices, while improving electrical performance and thermal insulation.

Aerospace and Automotive:

In aerospace and automotive manufacturing, epoxy hardeners are used to make lightweight composites, such as carbon fiber and glass fiber reinforced plastics, to improve the strength and stiffness of the composite, reduce weight and improve fire resistance.

Medical equipment:

In the manufacture of medical devices, epoxy curing agents are used to manufacture medical materials such as bionic bodies and artificial joints, improve the durability and corrosion resistance of these materials, and extend the service life.

Market trends and major vendors

With the acceleration of urbanization and the improvement of people's requirements for building and electronic environment, the application prospect of epoxy curing agent is very broad. At the same time, the development and application of environmentally friendly epoxy curing agent has also become an important trend in the market. Major manufacturers in the global epoxy curing agent market include Asia Dragon, Wanhua Chemical, Huntsman, Ishichemical, Evonik and so on. These enterprises have a relatively complete industrial chain and technical support, and continue to introduce new varieties and new technologies to meet market demand.

In short, as an important chemical material, epoxy assimilators play an important role in improving the hardness, strength and durability of materials, providing better solutions for different industries. With the continuous progress of technology and the expansion of application fields, the market prospect of epoxy curing agent will be broader.
