In coatings, inks, plastics and many other fields, titanium dioxide (titanium white pigment) is widely used for its excellent whiteness, hiding power and chemical stability. However, its high surface energy makes it prone to agglomeration and difficult to disperse, a problem that has long troubled production and R&D personnel. Agglomerated titanium dioxide particles not only affect the gloss, hue and hiding power of the final product, but may also cause sedimentation and flocculation, seriously undermining product storage stability and performance.
The market generally faces core pain points such as poor dispersion stability, low grinding efficiency and high formulation costs. Conventional dispersion methods are often inadequate, calling for the intervention of professional and efficient chemical dispersion solutions.
To address these challenges, Chemi Tech, drawing on deep experience in surface chemistry, has developed a series of high-performance dispersants dedicated to titanium dioxide. The core of our solution lies in precise molecular design: the anchoring groups of the dispersant firmly adsorb onto the surface of titanium dioxide particles, while the solvating chain segments extend fully in the medium, forming strong steric hindrance and electrostatic repulsion that prevent particles from agglomerating again at the root.
The specific implementation steps are clear and definite: first, our technical team conducts an in-depth analysis of your specific application system (such as solvent-borne, waterborne or plastic systems) and the titanium dioxide grade. Then we recommend the best-matching Chemi Tech dispersant, for example the CT-100 series designed for highly polar systems, or the CT-200 series suited to low-polarity environments. In the initial laboratory evaluation, we guide customers to determine the optimal dosage and addition sequence of the dispersant, usually recommended before grinding to achieve better wetting and de-agglomeration. Through simple grinding or high-speed dispersion, slurry viscosity can be significantly reduced while fineness and gloss are improved. Finally, long-term storage stability tests are conducted to verify that the dispersion effect is lasting.
We once helped an industrial coatings manufacturer in East China solve titanium dioxide sedimentation and uneven gloss in its solvent-borne system. After adopting the Chemi Tech CT-110 dispersant and optimizing the process, its titanium white slurry maintained a dispersion fineness stably below 15 microns, showed no hard sedimentation after six months of storage, and the resulting coating film achieved a 20% increase in gloss, while cost losses from rework were reduced. The customer spoke highly of the market competitiveness of the final product.
Choosing Chemi Tech means choosing not just a product, but a complete technical support system covering problem diagnosis, product selection, process optimization and performance verification. We are committed to helping customers overcome dispersion difficulties, unlock the full performance potential of titanium dioxide and enhance product added value.
