How to Solve Organic Pigment Dispersion Challenges? Chemi Tech Offers Efficient Dispersant Solutions

In the application of organic pigments, the dispersion effect directly determines the final product's color performance, gloss, and stability. Many production processes often encounter challenges such as pigment particle agglomeration, underutilized coloring strength, sedimentation and re-coarsening of color paste after storage, and noticeable color differences between batches. These pain points not only affect product quality but also lead to reduced production efficiency and increased costs.

Chemi Tech deeply understands these challenges. Based on in-depth research on pigment surface characteristics, we have developed a series of high-efficiency dispersants for organic pigments. The core of our solution lies in the precise design of molecular structures, which can rapidly wet the pigment surface and stabilize the pigment particles in the system through strong anchoring groups and steric hindrance, preventing re-agglomeration.

The specific implementation involves four steps: First, diagnosis and analysis. Our technical team will understand your pigment system, resin medium, and process conditions. Second, product recommendation. Based on the analysis, we match the most suitable Chemi Tech dispersant model for your system. Third, process optimization. We provide specific recommendations on dosage and dispersion process parameters (such as speed and time). Fourth, effect verification. We assist you in evaluating the fineness, coloring strength, gloss, and storage stability after dispersion.

We once assisted a coatings manufacturer in resolving dispersion issues with their phthalocyanine blue system. The customer's original formulation suffered from weak color development, low gloss, and significant re-coarsening after just one week of storage. After technical evaluation by Chemi Tech, a polymer dispersant with a special block structure was recommended. After adjusting the addition ratio and optimizing the grinding process, the produced color paste maintained a fineness below the micron level long-term, coloring strength increased by approximately 15%, gloss improved significantly, and after three months of storage testing, there was no hard settlement, and fluidity remained excellent, successfully achieving product upgrade.

Choosing Chemi Tech means not only selecting a dispersant but also acquiring a solution that ensures stable and reliable pigment dispersion quality. We are committed to helping customers unlock the full potential of pigments and enhance product competitiveness.
