Product Description
LOCTITE ABLESTIK 12-1 is a one-part, heat-cure silicone adhesive designed for general assembly bonding at operating temperatures up to 200°C. Supplied as an off-white, unfilled paste, it cures via a heat-activated schedule and offers approximately seven times the thermal conductivity of unfilled silicone adhesives. The adhesive is reworkable after cure, supporting rework or rework-sensitive assembly processes. It is packaged in metal squeeze tubes for dispensing and is intended for applications where thermal management and temperature-resistant bonding are required, with a primer recommended for improved adhesion on certain substrates.
Key features
- Thermally conductive: Roughly seven times the thermal conductivity of unfilled silicone adhesives.
- Reworkable: Cured bonds can be reworked, supporting rework and rework-sensitive assembly.
- High-temperature capability: Rated for continuous operating temperatures up to 200°C.
Applications / Suitable for: General assembly bonding where heat resistance and thermal conductivity are required.
