The easy-to-handle two-component epoxy resin exhibits good adhesion to different plastics, including polyamide and ABS. It offers a compression shear strength of 20 MPa on polyethylene after plasma treatment. With an elongation at tear of 5%, DELO-DUOPOX CR8031 is tough-hard and can withstand permanent temperatures up to 180°C. After 1000 hours of storage at this same temperature, and after 1000 hours at 85°C and 85% air humidity, the product’s mechanical properties remain the same. Resistant to oil and fuel, the compound is well suited for potting sensors and printed circuit boards or sealing housings in the engine compartment of vehicles.
This new epoxy resin achieves reliability and flows easily without any fillers, allowing for no risk of filler sedimentation. No stirring or degassing of the potting compound is needed, resulting in a simpler system design. Mixed in a 2:1 ratio, the multi-purpose casting compound can be applied as if it is a one component adhesive through dispensing guns with static mixing tubes. It is optimized for fast production and can be heat-cured within 10 minutes at 80°C.
