We engineered the bandgap of our Enhanced Sunblock™ to maximize absorbtion over the ultraviolet and deep blue spectrum (the green absorption spectrum line in the graph to the right). It is designed for enhanced absorption of high-energy light for use in protecting materials and people from their harmful effects, rather than for photocatalysis.
For example, titania is currently used in sunscreen to absorb the ultraviolet before it can reach our skin to do damage. But the deep blue rays that are not blocked by titania are blocked instead by organic compounds in the sunscreen. Evidence is mounting that these compounds can form carcinogens in the process of absorbing the blue light.
Our Enhanced Sunblock™ powder absorbs nearly all the ultraviolet as well as the deep blue, eliminating the need for organic compound absorbers.
And because it is titania, it remains inert in the process.
We also produce our Nanoptek Yellow™ by a similar proprietary process. It is a vibrant and ultra-stable yellow pigment (we also produce Nanoptek Green™ that is more of a moss green) to color any number of coatings and materials. And unlike other complex inorganic colored pigments (CICPs), ours contain NO HEAVY METALS.
In addition to it’s unique spectral absorption (green line in the set of spectra at right), our pigment has excellent reflection: over 90% in the non-absorbing region, shown in the reflection spectrum below. This is superior to other CICPs and produces a brighter and more saturated color. Moreover, its high reflectance in the near infra-red results in cooler surfaces, helping to protect materials damaged by heat absorption, and reducing heat load.
