Pigments for cellulose

For preparation of cellulose paint pigment paste requires some materials and ingredients that are short oil alkyd resin, nitrocellulose solution, paint pigment powder,wetting agent, cellulose thinner, solvents and etc.

Cellulose paint pigment paste can be prepared different concentrated depending on market and using products are cellulose paints, cellulose primer,cellulose putty and etc.

Production of cellulose paint pigment paste is not very complicated. For the production, there is need usable and tried a formulation, raw materials and mixing tank. For raw materials to be used, quantities to be used and ingredients usage rankings, you should decide to look into this formulation. Therefore, formulation and product?on methods of cellulose paint pigment paste are important. If you have not a good formulation, you cannot make healthy and efficient production of any cellulose paint pigment paste

Interference pigments are often used to give cars that classy metallic look, and lipstick an alluring sheen. Typically created by depositing layers of a metal oxide, they generate colour by interference of light scattered at the interface of their nanostructure.

"Interference pigments are different from pigment based on light absorption, that is why they can look metallic,"

"Light interference is also responsible for the colour we see in a soap bubble – the water is colourless when we observe it in a glass, but as soon as we have a very thin layer of water the colours are easily recognisable."

Let there be lightThe pigment industry has long relied on the use of complex synthetic dyes or inorganic particles to produce colours and visual effects such as hues, brightness and shine.

A challenge for industry however is the fact that these pigments are often produced from inorganic materials that can be difficult to source. Many pigments also make extensive use of titanium dioxide, which at high levels can be harmful.

"One alternative for companies looking to be greener is to create interference pigment structures with plant cellulose," says Vignolini. "Many plants in fact produce colours through naturally occurring nanostructures."

In certain fruits and leaves for example, cellulose fibres are assembled at the nanoscale into structures that intensely reflect blue light. Replicating the natural assembly process within the plant cell, and embedding this into materials, could be the key to developing a range of cellulose-based photonic pigments.

The PixCell project sought to take this concept further in two respects. Firstly, it identified possible sustainable and renewable sources for cellulose, such as wood left over from the paper manufacturing industry.

Secondly, it demonstrated that the project’s patented method of controlling the assembly of cellulose nanocrystals to produce photonic pigments could be scaled up to manufacturing levels. A key advantage of this approach to industry is that the technique can be readily adapted to existing industrial emulsion technologies.

"In a previous European Research Council funded project, SeSaMe, we discovered that naturally occurring cellulose nanocrystals are capable of specific colour," adds Vignolini. "With PixCell, we wanted to build on this discovery and make a pigment out of this."

Forging industry linksScaling up enabled the project to produce enough material to send to potential industrial partners. These companies, from fields ranging from automotive to cosmetics, were then able to test the material in their own formulations.

"Any industry that uses colour could be a potential end user," says Vignolini. "For example, we worked with printing companies interested in using interference pigments as ink for products such as fancy labels."

Vignolini believes that forging strong collaboration and know-how exchange with industry was perhaps the project’s biggest achievement. "We worked closely with many companies throughout the project and were able to generate knowledge and awareness about this new technology and learn relevant industrial processes," she explains.

The project team is currently thinking about creating a spin-off company to support the move towards commercialisation. "As a research lab, this part of the journey is challenging," she notes.

"We need to build up a supply chain, and also be realistic about the time it will take to bring this innovation to market. Nonetheless, our proof of concept was an important milestone to demonstrate scalability of the technology."
