Momentive RTV 655 Silicone Rubber Compound Clear A/B 10Lb (4.5Kg) Kit

Momentive RTV 655 Silicone Rubber Compound Clear A/B 10Lb (4.5Kg) Kit
RTV 655 is a 2 Part RTV pourable silicone rubber compound that protects electronic components and assenblies against shock, vibration, moisture, ozone, dust, chemicals and other environmental hazards by potting or encapsulation of the components and assemblies. It protects at low temperature (-115°C - +200°C) and is Crystal Clear, 10:1 mix ratio, accelerate cure by heat, deep section cure, ideal for potting solar cells.

These compounds are clear and colourless but differ in low temperature flexibility. Both are low viscosity, easily pourable liquids with nominal viscosities ranging between 3000 and 7000 mPa·s.

The optical clarity of the silicone rubber compounds suggests evaluation for applications such as potting solar cells for maximum light transmissions and electronic assemblies where component identification is necessary or desirable.  RTV 655 silicone rubber compound is preferred where flexibility at temperatures down to -115°C is required.

Key Performance Properties

  • Convenient 10:1 mixing ration use in automatic dispensing or hand operations
  • Low viscosity allows easy flow in and around complex parts, providing excellent electrical insulation and shock resistance
  • Cure rate can be acclerated by heat
  • Will cure in deep sections or enclosed assemblies without exotherm and with low shrinkage
  • Chemical composition contains no solvents for ease of use on production lines
  • Reversion resistance and hydrolytic stability permit use in high humidity environments at elevated temperatures
  • Clarity permits visual inspection for easy identification and repair of encapsulated parts
  • Retention of elastomeric properties at temperatures up to 200°C
