Description

The AS1802 is a non-corrosive, neutral cure, 1-part, RTV (Room Temperature Vulcanising) silicone adhesive sealant. It is one in a range of Acetone cure products which are solvent-free. It exhibits excellent primerless adhesion to many substrates and cures rapidly 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.

Key Features:

  • Excellent thermal conductivity
  • Non Corrosive
  • Fast Skinning
  • Low linear shrinkage

Applications: Automotive, thermal transfer, and bonding/potting in PCBs
