Material Notes:
Two-part condensation cure. Two-part condensation cure silicones RTVs are designed to cute at room temperature, and can be applied at temperature up to one inch (2.5 cm). These are very tough materials, highly resistant to contamination, and will not be affected by other chemicals during cure or after. Typical uses: Electronic assemblies and components.Data provided by the manufacturer, GE Silicones.GE Silicones became a part of Momentive Performance Materials in 2006.
