Why choose epoxy structural adhesive?
核心优势
>20MPa ultra-high shear strength
This two-component epoxy resin with amine curing agent exhibits extremely high crosslinking density. The steel-to-steel lap shear strength exceeds 20 MPa (ISO 4587), achieving structural bonding levels. It can replace traditional welding (no heat deformation) and bolted connections (no stress concentration). It is widely used in automotive, aerospace, and building reinforcement.
Multi-substrate universal bonding
It exhibits excellent adhesion to a variety of substrates, including metals (steel/aluminum/stainless steel/copper), composite materials (CFRP/GFRP), concrete, stone, ceramics, and wood. It also shows some adhesion to oiled steel surfaces (oil shear > 15MPa), reducing surface treatment requirements.
Fatigue resistance and aging resistance
Epoxy structural adhesives exhibit excellent fatigue resistance (fatigue strength >8 MPa after 1 million cycles). They are resistant to water, salt spray, oil, and solvents. Temperature resistance ranges from -40°C to 120°C. Service life is >50 years in building reinforcement applications.
Professional coating technology support services
Kexin boasts an experienced coatings R&D and application technology team, providing comprehensive services from substrate analysis, coating selection, and process parameter optimization to on-site application guidance. We work in conjunction with our clients' coating production lines to fine-tune coating application parameters, ensuring optimal coating quality and production efficiency.
Environmentally compliant green manufacturing system
All products are RoHS/REACH certified and meet national environmental standards for VOC content. Water-based and high-solids, low-VOC formulations are continuously iterated to meet increasingly stringent environmental protection requirements. Environmental performance test reports from authoritative third-party testing institutions such as SGS and CTI are provided.
Comprehensive quality control and batch traceability
A comprehensive quality control system is in place from raw material intake to finished product delivery. Each batch of products undergoes rigorous physical and chemical performance testing and coating simulation testing. Batch numbers are fully traceable, allowing for tracking of raw material origins and production process data. Each product comes with a batch test report and product warranty certificate for customer peace of mind.

常见问题
施工流程
Surface treatment
Thoroughly clean the substrate to remove oil and rust. Sandblast steel to Sa2.5 grade. Perform surface pretreatment according to product requirements. Ambient temperature 5-40°C, relative humidity...<85%。
Primer/Pretreatment
Select the appropriate primer or pretreatment based on the substrate and product system. Strictly control the film thickness by mixing according to the product ratio. Proceed to the next process after the primer has dried.
Main coating application
Apply the main coating according to the process requirements. Strictly control parameters such as film thickness, temperature, and humidity. Ensure a uniform coating free of sagging and pinholes.
Curing process
Bake or air dry at room temperature according to product requirements. Increase oven temperature gradually and evenly. For room temperature curing, ensure adequate ventilation and humidity.
Inspection and Acceptance
We test all indicators, including film thickness, adhesion, and gloss. Once all indicators pass, we issue a test report and quality assurance certificate, and ship the product in dust-free packaging.
