Two-component potting compound protects sensors reliably

DELO-DUOPOX CR8031 potting compound for automotive and power electronics protects electronic components such as sensors even at high temperatures and is easy to handle. Two-component epoxy resin shows good adhesion to various plastics such as PA or ABS. Even with PE, a compression shear strength of 20 MPa was reached after plasma pretreatment, although this cheap and resistant plastics is difficult to bond due to its low surface energy. With an elongation at tear of 5 %, product is tough-hard and withstands permanent temperatures of up to 180 °C. Even after 1000 hours of storage at maximum temperature of use, or at 85 °C and 85 % air humidity, the product’s mechanical properties remain unchanged. Furthermore, it is resistant to oil and fuel, a property that makes it suitable for applications in the engine compartment – for example for potting of sensors and printed circuit boards or for sealing of housings.
