Against the backdrop of accelerated upgrading in new energy, semiconductors, and high-end equipment manufacturing, epoxy curing agents have evolved from traditional auxiliary materials into core functional components that determine product performance and reliability. With three major technological breakthroughs - ‌intrinsic flame retardancy, water-based environmental protection, and rapid curing‌ - we have broken the foreign monopoly on high-performance formulations, providing customers with curing agent system solutions that are ‌highly reliable, low in TCO (Total Cost of Ownership), and green throughout their lifecycle‌.

 Biet  Epoxy Curing Agent Classification & Supply System

Based on epoxy resin curing mechanisms, Byt offers a diverse range of curing agent products:

• ‌Applications‌: Heavy-duty anti-corrosion coatings, structural adhesives, epoxy intermediate primers, floor coatings, grinding wheels, etc.

‌Technical Principle‌: Through reactive groups that bond with epoxy groups, a three-dimensional cross-linked network structure is formed, converting linear molecules into thermosetting materials, thereby achieving:

• Mechanical strength: Bending strength up to 50-70MPa
• Heat resistance: High-temperature curing agents supporting long-term operation at 200℃
• Chemical stability: Resistant to water, acids, alkalis, and oil-based media
• Adhesion: 30% improved bonding strength with metal/plastic/concrete substrates

Core Application Solutions

Construction Sector

Epoxy curing agents are widely used in construction:

• Sealant adhesives for airtight sealing
• Self-leveling epoxy putty for easier application and stronger bonding
• Epoxy mortar with faster hardening and crack resistance
• Water-based epoxy curing agents for concrete repair, enhancing strength and durability
• Water-based epoxy floor coatings for commercial and hospital environments, offering wear resistance and environmental protection
• Water-based epoxy metal protective coatings for steel structures, with excellent anti-rust performance

Coatings Industry

In coatings, epoxy curing agents provide multiple benefits:

• Enhancing organic glass light transmission while improving wear and UV resistance, ideal for aircraft and automotive glass protection
• Effective corrosion prevention on copper, aluminum, and other metals
• Providing glossy, smooth, and waterproof finishes for paper and ceramic surfaces
• Insulating coatings for electronic components, resistant to high temperatures and humidity
• Durable alternatives to latex paints for walls
• Solving bonding issues between silicone rubber and metal

Electronics Industry

Epoxy curing agents are indispensable in electronics:

• Latent curing agents for new energy vehicle battery encapsulation, reducing curing time by 40%
• High-frequency coil insulation, maintaining stability in high-temperature and high-humidity environments
• Enhancing thermal-mechanical properties, reducing thermal expansion, and lowering dielectric loss in epoxy molding compounds, making electronic components more durable

The core functionality of epoxy curing agents relies on chemical reactions. Their reactive groups bond with epoxy groups to form a three-dimensional cross-linked network, converting linear molecules into thermosetting structures. This results in:

• Harder and more stable materials
• Improved heat resistance (with high-temperature curing agents enabling long-term operation at 200℃)
• Enhanced chemical resistance (resistant to water and corrosion)
• Stronger adhesion (firmly bonding with metal, plastic, and concrete, preventing coating detachment)
•  

Product Performance Advantages

Rapid Curing

• Taking T-31 curing agent as an example, it can rapidly cure epoxy resins at room temperature, low temperatures (above 0℃), and humid environments, outperforming traditional amine-based curing agents.
• At room temperature, curing degree can reach over 91% in 24 hours; post-curing treatments (e.g., 40℃, 80℃, 120℃ stage processing) can significantly enhance shear strength.

Enhanced Durability

• Cured epoxy resins exhibit excellent heat resistance, chemical corrosion resistance, water resistance, and insulation properties.
• For instance, epoxy resin mortar forms a three-dimensional network structure through cross-linking polymerization, with tensile strength exceeding 10MPa and resistance to acids, alkalis, and oil-based media.

Mechanical Performance

• High shear strength, good toughness, and strong impact resistance in cured materials.
• Adding fibers (e.g., polypropylene fibers) can disperse stress, reduce shrinkage cracks, and improve material toughness.

Operational Flexibility

• Broad ratio range, with no strict requirements on dosage, facilitating construction.
• For example, the standard ratio for T-31 curing agent with E44 epoxy resin is 100 parts resin to 15-40 parts curing agent, with specific dosages adjustable based on ambient temperature.
