Global Latent Curing Agents for Epoxy Resin Market Strategic Research Report

Scope of the Report

The global Latent Curing Agents for Epoxy Resin market size is predicted to grow from US$ 378 million in 2025 to US$ 597 million in 2032; it is expected to grow at a CAGR of 6.8% from 2026 to 2032.

Latent curing agent is a curing agent that has certain storage stability at room temperature after being combined with epoxy resin, and can quickly cross-link and cure epoxy resin under conditions such as heating, light, moisture or pressure.

Now most epoxy curing agents are two-component, they not only need to be packaged, stored and transported separately, which brings many operational and environmental problems, but also measurement errors and uneven mixing during mixing and preparation can easily cause fluctuations in important properties such as the adhesive strength of the product. The viscosity of the system continues to increase with the progress of the chemical reaction, and its service life is limited. It is not suitable for the new automatic bonding process, and it is easy to cause scrap.

The development of one-component epoxy resin curing agents with improved quality and suitable for new processes has always attracted people"s attention.

The research and development of latent curing agent is the most active and important. This type of curing agent is mainly implemented by temporarily blocking or passivating the active groups and structures of some curing agents with high reactivity and poor storage stability. Many general-purpose two-component rings The low-temperature, medium-temperature and high-temperature curing agents of epoxy resin adhesives are developed by adjusting and controlling the reactivity by physical and chemical means. After this type of curing agent is added to epoxy resin, it has good room temperature, Storage stability under normal pressure. During use, external physical and chemical factors such as moisture, light, heat or pressure can be used to activate relatively stable curing agents according to different mechanisms and participate in the curing of epoxy resin.

The key manufacturers of latent curing agents for epoxy resin in the world include Westlake (Hexion), Asahi Kasei, Dasen Material, Alzchem Group, Shikoku Chemicals Corporation, Ajinomoto Fine-Techno, T&K toka and Mitsubishi Chemical, among which the top three manufacturers have more than 30% market share. The global production of latent curing agents for epoxy resin is mainly distributed in North America, Europe, China, Japan and Southeast Asia, among which the first two major production regions account for more than 40% of the market share. At present, North America is the largest production region, accounting for more than 20% of the market share. In terms of products, the growth rate of fine powder is relatively faster, and the current market share exceeds 80%, followed by viscous liquid. As far as applications are concerned, electronics is the first application field, accounting for more than 65% of the market share, followed by automotive.
