The application scenarios of epoxy structural adhesives are as follows:
Electronics and Electrical Applications: In the electronics and electrical fields, epoxy structural adhesives are not only used for bonding mechanical structures, but also widely used to prevent electrical short circuits and other problems due to their good electrical insulation properties. Their high insulation performance ensures the safe operation of electronic equipment.。
Coatings Industry: In the coatings industry, epoxy structural adhesives are mainly used to prepare water-based coatings, powder coatings, and high-solids coatings. Their excellent bonding strength, chemical corrosion resistance, and low shrinkage rate make them widely used in pipelines, containers, automobiles, ships, aerospace, and other fields.。
Craft Applications: Crafts often need to showcase exquisite and unique designs. The application of epoxy structural adhesives in the craft field is mainly to increase the firmness and aesthetics of the product. Epoxy structural adhesives in this field may have a wider variety of choices in terms of color and transparency.
Motor Applications: In motor manufacturing, epoxy structural adhesives are mainly used to bond motor components, ensuring stability under high loads and frequent start-up conditions. Epoxy structural adhesives have high strength, high temperature resistance (they can remain stable in a wide temperature range of-40°Cto200°C), chemical corrosion resistance, and good electrical insulation properties, making it particularly important in motor manufacturing.。
Construction Applications: In the construction industry, epoxy structural adhesives are mainly used for bonding materials such as stone, ceramics, and glass. Due to the variable construction environment, the adhesive is required to have good weather resistance and anti-aging properties. In addition, construction epoxy structural adhesives also need to consider environmental protection performance, such as lowVOCetc.

Types of Hinnel Epoxy Structural Adhesives
1.Two-component Epoxy Structural Adhesive
Two-component epoxy adhesives are made by mixing two components. They have high transparency, fast curing, and can cure at room temperature, suitable for large-area bonding or applications requiring longer working times. They have extremely high bonding strength, and the cured structure is very strong. Two-component epoxy adhesives are widely used in bonding motor housings, brackets, and other components.
2.One-component Epoxy Structural Adhesive
Thixotropic paste-like, non-sagging, long-curing, one-component epoxy resin structural adhesive. Easy to use, it can be quickly cured by heating. Very long shelf life, at room temperature20~25℃can be stored for90days,0~5℃can be stored for180days, used for structural bonding or caulking, has strong toughness after curing, excellent bonding strength, and high-temperature resistance.
In summary, epoxy structural adhesives are materials with broad application prospects. Different structural adhesives have different application fields and characteristics due to their unique chemical properties and manufacturing processes. Therefore, when choosing structural adhesives, the selection should be based on actual needs and application scenarios.
