DELO develops adhesives for high-temperature applications

DELO, the manufacturer of industrial adhesives, has added new structural adhesives to its product range.

These products are mainly used when components to be bonded are exposed to temperatures up to +220 °C.   Adhesives resistant to elevated temperatures are particularly in demand in mechanical engineering and the automotive industry, for example for electric motors.They must prove high strength, and permanent resistance to environmental influences, such as gear oil. However, the strength of adhesives is highly dependent on the temperature: Many adhesives exhibit a strong performance drop at temperatures above +150 °C. DELO’s new high-temperature adhesives impress by an increased shear strength of 12 MPa at such temperatures, approximating a gain of 50 percent compared to established products.

Thanks to an increased glass transition temperature and an improved long-term temperature stability, up to 3 N/mm² are possible even when the bonded connection is subjected to +220 °C. The tensile strength after intensive tests, in which the adhesive is stored at a temperature of +220 °C for 1,000 h, is still above 80 percent of the initial value. This enhancement of one-component epoxy resins clearly expands their temperature range of use.

Powerful in mechanical engineering

The adhesives’ mechanical properties open up versatile application possibilities in mechanical engineering. For example, DELOMONOPOX HT282 with aluminum filler is used for bonding magnets in electric motors as it can withstand dynamic stress thanks to its high impact resistance. In contrast, DELOMONOPOX HT281 with mineral filler is electrically insulating. This product bonds and casts components in electric motors, and can also be used in applications where excellent chemical resistance is required, for example slide ring seals. Tried and tested processing properties enable simple and fast dispensing. In addition, the adhesives can be processed within a period of up to four weeks at room temperature. The new products are available in all standard containers.
