Structural Adhesive Offers High Temperature Stability

DELO has developed a structural adhesive that offers increased stability at high temperatures. DELO MONOPOX HT2860 achieves up to three times the strength at a temperature of 150°C compared to previous product generations.

Ideal for bonding magnets in electric motors used in cars, drilling, milling tools, washing machines, as well as in many other applications, this new adhesive has a glass transition temperature (Tg) of 168°C. As a result, the elasticity (Young’s modulus) below Tg does not change significantly, allowing the adhesive to achieve a very high temperature stability with flexibility only increasing if the temperature rises above 168°C. 

DELO MONOPOX HT2860 achieves a strength of 18 MPa on sand-blasted aluminum at 150°C. This is up to three times higher than standard epoxy resins.

Achieving a compression shear strength of 65 MPa on aluminum and 55 MPa on ceramics at room temperature, DELO MONOPOX HT2860 has excellent adhesion to metals, as well as to temperature-resistant plastics, ferrite compounds and ceramics.

The versatile epoxy resin can be heat-cured in an oven for 40 minutes at 150°C or by induction. Induction-curing requires metal joining partners and enables a reduction in the process time by 90%.

DELO MONOPOX HT2860 has a processing time at room temperature of four weeks before curing and an operating temperature range of -55°C to 220°C. It is suitable for bonding under high static or dynamic loads.
