Step aside, Vantablack. There’s a new superblack paint in town.
Named to reference the center of a black hole, Singularity Black is a solvent-based paint full of carbon nanotubes that absorb almost all light, from the visible to the long-wave infrared, that falls on them. You can apply it with a brush or even with a spray gun, to make objects look utterly flat, even if their surfaces are incredibly textured. The above screw, for instance, was coated in Singularity Black, and it disappears when set against a sheet of wrinkled aluminum foil, also coated in the pigment.
Singularity Black is technically less black than Vantablack, which is also chock-full of carbon nanotubes. The latter exhibits lower reflectance in the visible range — about 0.2% total hemispherical reflectance (THR) at 700 nm — and Singularity Black exhibits about 1.15% THR at 700 nm, Preston said.
But Singularity Black has the lowest visible reflectance of any paint in the world that is generally available to the public. You can buy it right now, by contacting NanoLab’s sales department, in volumes of 250mL, 500mL, or 1000mL. Preston, however, advises that artists first purchase a 20mL artist sample to experiment with Singularity Black and get acquainted with the prescribed coating techniques and its required treatment process. The artist sample, which resembles a vial of nail polish, costs $30 (shipping not included).
