High Aspect Ratio NanoFlakes

Sigma, using its proprietary multi-layer deposition technology, has the ability to produce high aspect ratio particles, or "NanoFlakes," composed of various organic and inorganic materials.

Sigma utilizes a proprietary process for simultaneous deposition of polymer and various metal and ceramic coating to produce multi-layer nano-composite. The bulk nano-composite is reduced into a fine polymer/metal or polymer/ceramic powder, which can be further reduced to a pigment or particle for use in a variety of applications including multi-functional paints, inks, and coatings, IR signature reduction, and high-energy explosives and propellants.
