OCSiAl has introduced new graphene nanotube solutions in the form of water-based dispersions with low solid content for films, coatings and packaging. According to the company, applications for these include ultra-thin coatings, such as UV coatings and coatings on polyethylene terephthalate (PET) and anti-static binders with no changes in processing and retained level of rheology.

The expanded product line includes nanotube water-based dispersions stabilized by anionic surfactants. The dispersions will be used in ultra-thin coatings where retained processing and rheology are essential, as well as in applications where polymer-based systems are used, including anti-static UV coatings and coatings on PET, binders and primers. A BA dispersion is also said to be under development.

The expansion of the graphene nanotube-based dispersion product line was  developed to target new markets for nanotube use. “We’ve noticed that the packaging and film industries prefer to use dispersions with 0.2–0.4% content of graphene nanotubes,” says Ekaterina Gorbunova, development and support leader for elastomers, vice president, OCSiAl Group. “The recently developed products have an extremely fine quality of nanotube dispersion and are easier to handle in specific applications, especially with low solid content. It allows manufacturers to produce thin coatings that are stable over time with minimal impact on the color or transparency of the final products.”

The company plans to scale-up production of these new dispersions and to target regions such as Asia, Europe and the U.S.
