Thermal Conductive Paste.
A two-part inorganic thixotropic sealing compound built for heat transfer. Mix 5:1, trowel a 1–2 mm layer between copper pipe and surface — gels in ~10 min, cures in 25–30 min at room temperature, then survives −80 °C to +150 °C without melting.

Application steps
Six steps, one technician
- 1
Prepare
All surfaces must be free of oil, dust and surface coatings. A light abrasion improves mechanical key.
- 2
Stir
Stir the paste container to overcome any ingredient settlement during storage.
- 3
Mix
Combine paste and hardener at 5:1 by weight (e.g. 200 g paste + 30 g hardener) until uniform.
- 4
Load & Apply
Load into an empty silicone cartridge and gun out — or trowel a 1–2 mm layer covering the full contact surface.
- 5
Seat
Press the components together so every surface is fully wetted. Gel in ~10 minutes.
- 6
Cure
Hardens by air-drying and operational heat. Full cure in 25–30 minutes at room temperature.
If moisture is present after mixing, foam may form — add moisture powder or contact our representatives. Curing time can be tuned to customer preference.
