    Application
    CPU-42-BC30A-A/B is the transparent potting materials for sealing material between electrical device and housing. It can also be used to cast for other suitable products.
    Characteristic
    1. Halogen free
    2. Flame retardant grade: UL-94-V2 (1.8mm)
    3. Soft grade and can absorb vibration
    4. Highly transparent sealing material
    5. Good at blocking moisture
    6. Great repairability
    Advantage
    1. Solvent-free (100% solid content)
    2. Great electrical characteristics
    3. Low initial viscosity after mixing (The performance is compared to solvent-free two component casting resin)
    4. The reaction of mixture starts at room temperature (The reaction is speeded up at higher temperature)
