Highest Quality, Purity & Consistency

What is a Nanodiamond (ND)?

Nanodiamond (ND) is a Nano-crystallite particle of hybrid carbon cubic structure <100 nm, with chemically active surface radicals and inert diamond core the average size of 4-5 nm (≈1/10,000 of a human hair thickness).

Adding small amounts of Nanodiamond particles imparts unique diamond-like mechanical and tribological properties, enhancing capabilities and improving functionality.
