Reinforced with aggregated diamond nano-rods -- a harder structure than SiO2 alone, and optically different on metallic paint. The diamond particles scatter light from inside the coating, intensifying metallic flake and pearl shimmer in a way standard ceramics don't. Built for show-quality finishes and complex metallics. 5-year warranty.

Warranty

Diamas contains Advanced Diamond Nanorods -- not ground diamond, but crystal rods created under extreme pressure and heat, harder than natural diamond. The nanorods reinforce the ceramic resin like rebar in concrete, but the difference most customers notice first is optical: diamond scatters light in a way glass doesn’t. On metallic paint and complex pearl finishes, that scatter intensifies the flake in a way standard ceramics don’t -- there’s a depth and sparkle to the finish that’s genuinely different.
Backed by our own no-fuss, 5-year transferable guarantee. See our full guarantee.
Is Diamas the right coating for you?
Diamas is for the customer who cares about how complex metallics and pearl finishes look -- not just protected, but alive. If your car has a multi-layer metallic or a strong pearl, Diamas will do things to the finish that a standard ceramic won’t. At the 5-year warranty level it sits between Matrix Black and LGS on price; a step up from ceramic without the full graphene commitment.
Diamas Professionali Diamond Coating
Advanced Diamond Nanorods are created by compressing carbon-60 molecules at extreme pressure and temperature -- the result is crystal rods about a micron long and harder than natural diamond. In a coating, they act like glass-fibre in fibreglass: anchors for the ceramic resin that strengthen the barrier and stabilise the optical layer. SiRamik manufacture it; we apply it as trained professionals.
What Diamas delivers
- Optical depth -- diamond nanorods scatter light from inside the coating, intensifying metallic flake and pearl shimmer in a way standard ceramics don’t produce.
- Super-hydrophobic -- with a sliding angle as low as 10 degrees, water beads and rolls off immediately, carrying surface contamination with it.
- 5-year warranty -- backed by SiRamik’s manufacturer guarantee and our own no-fuss, transferable warranty. See our full guarantee.
