Description

CHT AS1701 is a non-corrosive, neutral cure, 1-part, RTV (Room Temperature Vulcanising) silicone adhesive sealant. It is one in a range of Alkoxy cure products which are solvent free. It exhibits excellent primer-less adhesion to many substrates and cures at room temperature when in contact with atmospheric moisture to form a tough rubber. This product will not corrode copper or its alloys and is suitable for use with electronic components.

Benefits

  • Thermal Conductivity = 0.6 W/mK
  • Working Temperature = -50°C to 220°C
  • Dielectric Constant = 2.92

Features

  • Non corrosive
  • Excellent adhesion to most substrates
  • Fast skinning
  • Non slumping paste

Recommended Uses

  • Vibration damping and board coating e.g. voltage regulators
