Adhesives/Sealants

Low Volatility RTV Silicone Adhesive

DESCRIPTION
  • One-Part, RTV Condensation Cure
  • Oxime Cure
  • Non-Slump
APPLICATION
  • For applications requiring low volatility and high purity
  • Designed for protection of electrical components and assemblies against shock, vibration, moisture, dust, chemicals, and other environmental hazards
  • For bonding and sealing in applications such as overhead or vertical joints that require a non-slumping and one-part material
  • Bonds well to plastics such as polycarbonate
