Epoxy resins are versatile polymers widely used in various applications, such as adhesives, coatings, and composites. To achieve their full potential, epoxy resins require a curing agent, also known as a hardener. The curing agent plays a crucial role in the epoxy resin curing process, where it facilitates the transformation of the liquid epoxy into a solid, durable material with desirable mechanical and thermal properties.

There are different types of curing agents available for epoxy resins, including amine-based, anhydride-based, and mercaptan-based hardeners. Each type offers distinct properties and curing characteristics, making them suitable for specific applications. For instance, amine-based curing agents are known for their fast curing times and excellent adhesion properties, making them ideal for applications such as coatings and adhesives. Anhydride-based curing agents, on the other hand, are often chosen for applications requiring high-temperature resistance, such as in electronic encapsulation.

KEY FINDINGS

COVID-19 IMPACT

Market Growth Hampered by Pandemic due to Production Challenges

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to market’s growth and demand returning to pre-pandemic levels.

Many industries faced production slowdowns or shutdowns during the pandemic, affecting the production of epoxy resins and their curing agents. This has led to potential shortages and increased lead times for obtaining curing agents. Additionally, social distancing measures and health protocols may have impacted workforce availability, affecting production efficiency. The pandemic has influenced changes in consumer behavior and industrial priorities. Some industries, such as construction and automotive, experienced slowdowns, impacting the demand for epoxy resin and its curing agents. Conversely, sectors like healthcare, electronics, and packaging may have seen increased demand, influencing the type and quantity of curing agents required.

The pandemic has caused disruptions in global supply chains due to lockdowns, travel restrictions, and labor shortages. This has affected the availability and transportation of raw materials used in the production of curing agents. Manufacturers may face challenges in securing a stable supply of key components, potentially leading to delays and fluctuations in the pricing of curing agents for epoxy resin. The global curing agent for epoxy resin market growth is anticipated to boost following the pandemic.
