Technical Information

Momentive RTV102 White is a one-part, acetoxy-cure silicone sealant that cures to a clean white silicone rubber with excellent adhesion, flexibility, and environmental resistance. It shares the core performance characteristics of the RTV108 Clear but in a white color formulation for applications where appearance matters — such as appliance sealing, HVAC assembly, lighting fixtures, and white-surface industrial equipment. The cured sealant provides reliable moisture exclusion, vibration damping, and thermal stability across -65°C to +204°C, making RTV102 a trusted general-purpose white silicone sealant for both electronics and industrial manufacturing.
