Epoxy sealant | Oil pressure sensor packaging

Oil pressure sensors are usually installed in the engine lubrication system and are exposed to high temperatures, strong vibrations, oil and fuel vapors for a long time. They also need to withstand harsh working conditions such as cold and hot shocks, refrigerant immersion, salt spray, and humid heat.Therefore, materials used for packaging electronic components inside sensors must meet the following key performance requirements:Excellent oil resistance and chemical stabilityCan resist long-term erosion from fully synthetic engine oil, mineral engine oil, transmission fluid, gasoline vapor, and common refrigerants.Wide temperature adaptation rangeThe engine compartment environment temperature fluctuates greatly, requiring materials to have long-term temperature resistance of -40 ℃ to 150 ℃ and be able to withstand transient high temperatures of the engine.Reliable mechanical and insulation performanceIncluding anti vibration, anti cracking, and stable electrical insulation to ensure the long-term stability of sensor output signals.Low water absorption and sealing performanceLong term exposure to humid and hot environments requires materials to have excellent moisture resistance to avoid insulation performance degradation and metal pin corrosion.EP 1710A/B two-component epoxy potting materialEP 1710A/B is a two-component solvent-free room temperature curing epoxy potting material developed specifically for packaging automotive electronics, motors, power tools, and electrical instruments. Its performance highly meets the requirements for the use of oil pressure sensors and is the preferred packaging solution for this type of product. Main performance advantages
