Silopren LSR 4600 FC liquid silicone rubber is a family of platinum catalyzed fast cure two-component liquid silicone rubber offered in a variety of different durometers. With faster cure at lower temperatures such as 100°C, it is an excellent candidate to consider for injection molding onto lower temperature substrates such as polycarbonate.

Key Features and Benefits
  • fast cure at low temperatures
  • long pot life
  • UV resistance
  • ISO 10993/USP Class VI tested(a)
