Recently, Zhongzhan Technology has launched a new round of expansion projects, covering the expansion and upgrading of R&D laboratories, the construction of raw material production lines, and the building of modern storage workshops. This initiative aims to strengthen the company’s core competitiveness and accelerate the layout of its industrial chain. As a key measure for the company to deepen its presence in the fine chemical sector, this expansion marks a crucial step forward in its technological R&D and cost control efforts. Based on the company’s existing 2,000-square-meter laboratory building, a 500-square-meter expansion area will be added this time, focusing on upgrading the polymer material analysis laboratory and the formulation R&D center. After the expansion, the laboratory building will introduce advanced equipment such as Dynamic Mechanical Analyzers (DMA) and High-Performance Liquid Chromatographs (HPLC), enabling a full-process R&D closed loop from raw material purity testing to finished product performance verification. It is expected that R&D efficiency will increase by 30%, providing stronger technical support for the iteration of new-type epoxy curing agents and special amine-based products. Simultaneously, the construction of a new 20-mu (approximately 13,333-square-meter) factory area is also advancing, with plans to build a methanol production line and supporting storage facilities. After the commissioning of this production line, the company will achieve self-sufficiency in methanol—a core raw material. Through vertical integration of the supply chain, it is expected to reduce raw material procurement costs by 15%-20%, significantly enhancing the market competitiveness of its products. In the meantime, the new factory area will adopt intelligent control systems to realize full-process automation in raw material storage & transportation and reaction regulation, meeting high standards for environmental protection and safety.   This expansion is not only a strategic layout in response to the upgrading of the new material industry but also a concrete practice of the company’s "dual-driver (technology + cost)" development model. In the future, with a more comprehensive R&D system and a more optimized cost structure, the company will continue to provide high-quality products for fields such as coatings, adhesives, wind power, electronics, and composite materials, contributing to the green and low-carbon development of the epoxy resin and polyurethane industries.  

The T31 curing agent is a commonly used epoxy resin curing agent. The following are its main components and uses: Main components: The main component of the T31 curing agent is phenolic amine, which is made through a polycondensation reaction of phenol, formaldehyde, ethylenediamine, etc. This complex structure endows the T31 curing agent with unique properties. Main uses: In the coating field: In coatings, the T31 curing agent can undergo a cross-linking reaction with epoxy resin to form a tough, wear-resistant, and corrosion-resistant coating. It is widely applied to anti-corrosion coatings in fields such as ships, bridges, and buildings, and can effectively protect the surface of objects from the erosion of the external environment. In the adhesive field: As a curing agent for epoxy resin adhesives, the T31 can endow the adhesives with good bonding strength and water resistance, and can be used for bonding various materials such as metals, ceramics, and glass. In the composite material field: When manufacturing composite materials, the T31 curing agent can enable better combination between the epoxy resin matrix and fiber-reinforced materials, improve the mechanical properties and stability of the composite materials, and is commonly used in fields such as aerospace and automotive manufacturing. In the electrical insulation field: The epoxy resin cured by the T31 curing agent has good insulation performance and can be used for insulation potting and insulation coatings of electrical equipment to ensure the safe operation of electrical equipment.
