During coating production and storage, are you often troubled by these problems: pigment particles that cannot be fully dispersed, causing color difference and uneven gloss in the paint film; poor system stability, with hard settling or severe flocculation appearing shortly after storage, requiring frequent stirring; or having to grind repeatedly to achieve the desired state, which is time-consuming and costly. These dispersion challenges directly affect the quality, appearance and user experience of the final product.
Targeting these core pain points, Chemi Tech has developed a series of high-performance coating dispersants based on years of technical expertise. Our solutions not only focus on dispersion efficiency, but also aim to improve the long-term stability of the entire coating system.
Our solution path consists of four steps:
Step 1: Precise diagnosis. Our technical team analyzes your coating formulation base, the type of pigments used and your production process to identify the key points of dispersion failure.
Step 2: Product selection and matching. Chemi Tech has a rich dispersant product line, including high-efficiency wetting dispersants for inorganic pigments and strong steric-hindrance dispersants for organic pigments and carbon black. We will select the most suitable product for you.
Step 3: Process optimization advice. We provide specific optimization plans for the addition sequence, recommended dosage and dispersion process parameters (such as stirring speed and time) to ensure the dispersant performs at its best.
Step 4: Effect verification and follow-up. By testing fineness after dispersion, viscosity changes, storage stability (hot and cold storage) and paint film performance, we verify the effectiveness of the solution and provide long-term support.
Case study: An industrial coating manufacturer encountered uneven dispersion of carbon black and titanium dioxide in its gray topcoat formulation, resulting in tiny color specks and gloss fluctuation in the paint film. With the involvement of Chemi Tech's technical team, a high-molecular block copolymer dispersant was recommended and the feeding sequence was optimized. After the adjustment, pigment fineness improved significantly and remained stable over time, with no obvious settling after 30 days of hot storage at 50°C. The paint film gloss became uniform and consistent, and the customer was highly satisfied with product consistency.
Choosing Chemi Tech means you get not just a dispersant product, but a complete technical service from problem analysis to performance improvement. We are committed to helping coating manufacturers enhance product competitiveness and make dispersion no longer a bottleneck.
