Epoxy resins in automotive engineering
In the automotive industry, durability, safety, and efficiency are essential in order to meet the high demands placed on modern vehicle components. Epoxy resins make an important contribution to automotive engineering: they enable robust connections, functional coatings, and reliable protection for sensitive electronics. Special epoxy resin formulations make it possible to provide tailor-made solutions for the various requirements in the automotive industry, thereby ensuring the quality and longevity of vehicles.
Key product features
- High-performance epoxy adhesives: excellent strength, secure connections between epoxy bonding agents
- Thermal resistance: stability even at high temperatures, first choice for use in the engine compartment or near exhaust pipes
- Chemical resistance: resistant to oils, fuels, coolants, and other mediums, ideal for harsh operating environments
- Flexible potting compound: protection of delicate components such as ferrites
- Long processing time: specifically adjusted processing time enables clean application
Which epoxy resins are used in automotive engineering?
EPOXONIC offers specialized epoxy resins that are suitable for automotive engineering. Here are a few examples:
- EPOXONIC 361: A particularly flexible 2K casting resin characterized by low tensile strength and high elongation at break (70%). It is ideal for low-stress encapsulation of pressure-sensitive electronics, such as inductive components or pressure-sensitive sensors. With a water absorption of only 1.7% and a wide operating temperature range from -40 to +150°C, it remains reliably functional even under extreme conditions.
- EPOXONIC 366: This single-component, filler-containing casting resin system is particularly suitable for electronics encapsulation. It has an extremely high glass transition temperature of 170°C and also exhibits excellent mechanical strength. Typical applications are found in the field of sensors that are subject to high thermal and mechanical stress. The high density of the material (1.7 g/cm³) and its excellent dimensional stability make it a proven system for continuous use.
- EPOXONIC 370: A thixotropic, tough-elastic two-component epoxy adhesive that is characterized by its impact strength and crack resistance. It is ideal for bonding materials with different coefficients of expansion, such as aluminum and plastic – for example, in the assembly of housing parts or hybrid modules. It can also be cured at room temperature, allowing for flexible process control, and achieves maximum strength when heated.
