A thermal interface paste built from non-oxidising nano MWCNT, aluminium nitride, zinc oxide and surface-passivated aluminium powder in a silicone base. Nano modification and dispersion raise the compatibility between filler and substrate, which lets the paste carry a higher solids loading while staying workable. It also lowers the paste density, so a given weight covers roughly 1.5–2× the area — the same thermal spec at a lower cost per board.

Yes — surface resistivity is specified at greater than 10¹⁴ Ω/sq, despite the carbon nanotube content, because the conductive filler is dispersed within an insulating silicone matrix rather than forming a percolating network.
Standard filled silicone greases typically sit in the 1–3 W/m·K range. This is specified at 5.3 W/m·K under the stated bond line, and the lower paste density means more coverage per kilogram.
Three years, stored dry and dark.
1 kg bottle. Production is a 10 kg drum.
