Description
AS1700 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 primerless 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.
Key Features:
- Non Corrosive
- Excellent adhesion to most substrates
- Excellent dielectric and isolating properties
- Low odor
Applications: Fiber optic cables, bonding/potting PCBs
