As the core component of modern intelligent access control system, induction gate is widely used in office buildings, residential areas, factories and transportation hubs. In order to ensure the long-term stable operation of the induction gate, especially in various complex environments such as high temperature, high humidity or frequent mechanical vibration, high-performance potting glue must be used for protection. The potting glue not only needs to have excellent waterproof, dustproof and corrosion resistance, but also needs to provide excellent electrical insulation and mechanical stress relief functions to extend the product life.
Potting material requirements:
Waterproof: The induction gate needs to be exposed to the outdoors and be affected by rain, moisture, etc. for a long time. Therefore, the potting glue needs to have a protection level of IP67 or higher to ensure that the electronic components are not corroded by moisture.
Weather resistance: Adaptability to different environmental conditions, including high temperature, low temperature, UV rays, etc. The material must maintain stable performance in the temperature range of -40°C to +120°C.
Electrical insulation: To ensure the safety of circuit components in long-term operation and avoid the risk of short circuit or electric shock, the electrical insulation should reach 10^14 Ω·cm.
Mechanical properties: Good impact resistance and vibration resistance to ensure that the equipment will not be damaged under daily use and external impact.
Environmental requirements: Materials must comply with environmental standards such as RoHS and REACH.
