Product Introduction

The polyurethane potting compounds (CPU-42-BC30A-A/B and CPU-42-BC30D-A/B) are transparent two-component materials for electrical device and housing. The polyurethane potting compounds can also be used to cast for other suitable products.
  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)
