Tackling Coating Dispersion Challenges: Chemi Tech's Efficient Dispersant Solution Explained

In the process of coating production and storage, are you often troubled by these issues: pigment particles failing to disperse fully, leading to film color difference and uneven gloss; poor system stability, resulting in hard settling or severe flocculation shortly after storage, requiring frequent stirring; or the need for repeated grinding to achieve the desired state, which is time-consuming and increases costs. These dispersion challenges directly impact the final product's quality, appearance, and user experience.

Addressing these core pain points, Chemi Tech, leveraging years of technical expertise, has developed a series of high-performance coating dispersants. Our solution focuses not only on dispersion efficiency but also on enhancing the long-term stability of the entire coating system.

Our specific approach is divided into four steps:

Step 1: Precise Diagnosis. Our technical team analyzes your coating formulation base, the types of pigments used, and production processes to identify the key points of dispersion failure.

Step 2: Product Selection and Matching. Chemi Tech offers a comprehensive line of dispersants, including efficient wetting and dispersing agents suitable for inorganic pigments, and strong steric hindrance dispersants for organic pigments and carbon black. We will help you select the most compatible product.

Step 3: Process Optimization Recommendations. We provide specific advice on addition sequence, recommended dosage, and optimization of dispersion process parameters (such as stirring speed and time) to ensure the dispersant performs at its maximum effectiveness.

Step 4: Effect Verification and Tracking. By testing fineness after dispersion, viscosity changes, storage stability (hot and cold storage), and film performance, we verify the solution's effectiveness and provide ongoing support.

Case Study: An industrial coatings manufacturer faced issues with uneven dispersion of carbon black and titanium dioxide in its gray topcoat formulation, resulting in tiny color spots and fluctuating gloss in the film. After engagement by the Chemi Tech technical team, a polymeric block copolymer dispersant was recommended, and the feeding sequence was optimized. Post-adjustment, pigment fineness significantly improved and remained stable long-term. No significant settling was observed after 30 days of hot storage at 50°C, and the film gloss became uniform and consistent. The customer expressed high satisfaction with the improved product consistency.

Choosing Chemi Tech means you receive not just a dispersant product, but a complete technical service package from problem analysis to performance enhancement. We are committed to helping coating manufacturers enhance product competitiveness, ensuring dispersion is no longer a bottleneck.
