- Features
Electrically Insulating, Good Damping, Good Mechanical Properties, Low Viscosity, Platinum Catalyzed, Resilient, Soft, Tacky. P-429 has a low viscosity that allows for easy mixing, dearing, and pouring. It is used for potting or encapsulating electrical parts where visual inspection is required. It has excellent electrical insulating properties and provides superior damping characteristics. P-429 has greater mechanical properties than traditional gels and can be used in conjunction with platinum cured special effect silicones to produce realistic simulations of living tissue
