Elantas Bectron® PU 4513 is a soft, elastic polyurethane. It features low shrinkage and excellent insulation properties, offering superior mechanical and chemical protection. You can use this product for potting sensitive components and PCBs, especially in outdoor applications.
Highlight Features
- High Flexibility: The polyurethane retains flexibility even at sub-zero temperatures, down to -40°C.
- Dielectric Properties: It provides strong dielectric properties for reliable insulation.
- Versatile Curing: You can cure it at room temperature or use heat curing as an option.
- Thermal Conductivity: It effectively manages heat due to its good thermal conductivity.
- Solvent-Free: The formula does not include solvents.
- ROHS Compliant: It meets ROHS standards for environmental safety.
Applications of Elantas Bectron® PU 4513
Elantas Bectron® PU 4513 works well for potting sensitive components and PCBs, particularly in outdoor environments. The processing time is about 50 minutes, during which the viscosity increases. For batch production, prepare the volume to fit within this processing time. If you use metering equipment, you can reduce the setting time with accelerators.
