R-618 is a premium rutile titanium dioxide pigment manufactured via the sulfate process, specifically engineered to deliver outstanding opacity and durability.
It is highly versatile and widely used in industrial coatings, printing inks, paper production, and other general-purpose applications.
Through an advanced, fine grinding manufacturing process, R-618 achieves a highly uniform particle size distribution, which directly translates to superior gloss in end products.
R-618 undergoes a specialized inorganic surface treatment with Zirconium (Zr) and Aluminum (Al), along with an organic treatment, to enhance weather resistance and leveling properties.
R-618 features a low oil absorption value of ≤18 g/100g, which contributes to excellent dispersibility and lower viscosity in formulation processes.
