The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pigment regrind stage. The research will investigate the development of a highly durable dry-coated pigment utilising a novel high dielectric coating. This development has the potential to ensure the partner company's future competitiveness through reduced processing costs and improved product performance.

合作伙伴公司Tiwest位于西澳大利亚州，是澳大利亚经济的主要贡献者，每年出口收入超过4亿澳元。它是世界上唯一一家在一个地区开采、分离、精炼和制造包括颜料在内的二氧化钛产品的公司。然而，目前的二氧化钛颗粒形成后湿涂方法存在主要的资本和经常性成本，并且需要颜料再研磨阶段。该研究将研究利用新型高介电涂层开发高度耐用的干涂颜料。这一发展有可能通过降低加工成本和提高产品性能来确保合作伙伴公司未来的竞争力。
