DELO-Application areas – Automotive

Adhesives for chip and sensor casting in the automotive industry must withstand extreme chemical stress and elevated temperatures from -65 °C to +200 °C.

Both DELOMONOPOX (1C) and DELO-DUOPOX CR (2C anhydrides) unify excellent adhesion, optimally adjusted flow properties and variable curing parameters. They reliably retain their properties even after years of use.

When casting sensors, the sensor module is cast on the printed circuit board in a housing. It is essential that the casting protects the sensor against chemicals, such as gasoline, diesel, oils and cleaners. The highly reliable 2C anhydrides are especially suitable for this task.

When encapsulating chips (COB), SMD components are Dam&Fill-encapsulated. Several adhesive beads are stacked as “Dam” and subsequently “Fill”-ed. The finished encapsulation protects the component or the sensitive electronic parts from environmental influences.

A multitude of sensors are used in cars. These include position sensors, speed sensors, concentration sensors, pressure sensors, fill level sensors, and many more. Bonding sensors requires special adhesives. They must protect the sensor from the environmental conditions prevailing at the point of use, such as elevated temperatures, high pressure, or aggressive media. The open contact areas of the housing must be reliably covered and protected from corrosion.

DELO’s light-curing adhesives enable the reliable sealing of microswitches, relays and connectors, fixing of electronic components, and bonding of housing parts. Applications in the automotive industry in particular require fast bonding processes combining short cycle time with reliable process control. DELO’s light-curing adhesives are excellent for this purpose: Fast curing within seconds by exposure to light (“curing on demand”) enables immediate in-line quality control. This is how component defects can be detected promptly and necessary remedial actions can be taken, saving time and cost.
