Leveraging advanced thermo-mechanical properties, ERICW EW-9708 delivers nanoscale protection via fluorinated acrylic polymer technology (8% solid content in hydrofluoroether solvent). With UV tracer for quality control and rapid drying (≤5 sec at 25°C), it provides extreme moisture resistance (water absorption ≤0.1%) and dielectric strength (≥25 kV/mm). Compliant with RoHS and VOC-exempt standards (EPA SNAP), it enables sustainable solutions for automotive electronics and industrial PCBA.
Excellent protection performance: It has good moisture and corrosion resistance, and can effectively resist oil, water, hydrocarbons, silicone resin and photoresist, etc.
Good electrical performance: It has good dielectric properties, thermal stability and electrical stability, which can ensure the stable operation of electronic equipment in different environments.
Convenient construction performance: It can be dried in seconds without heat post-curing. Only a small amount or no covering is required, and it can be repaired after being worn, which is easy to remove and convenient for rework and repair.
Good environmental performance: Low volatile organic compound (VOC) content, low global warming potential,
Consumer electronics: such as printed circuit boards and internal electronic components of mobile phones, laptops, tablets, etc. Protection can improve the reliability of equipment in daily use.
Communication equipment: used to protect circuit boards and electronic components in outdoor communication facilities so that they can maintain stable performance in harsh natural environments.
Automotive electronics: protect the circuit boards of the electronic control system and on-board electronic equipment of the car to ensure that they are not affected by moisture, oil, etc. during the operation of the car.
Industrial electronics: can be used to protect electronic components of various industrial automation equipment, instruments, etc., to extend the service life of the equipment and ensure the stable operation of industrial production
