This material consists of nano-size silicon flakes each covered with a titanium compound. The flakes possess amazing light scattering properties if mixed with clear varnishes or polymers.

The material can be mixed into practically any clear medium to produce optical fireworks’ and colourchanging characteristics. 5g (approx. 20ml) pot (colour shift: red to green).Please note: this small quantity covers a huge area as a surface finish or fills large volumes if embedded in clear resin etc.
