In the application of organic pigments, the dispersion effect directly determines the final product's color performance, gloss, and stability. Many production processes often face challenges such as pigment particle agglomeration, insufficient development of tinting strength, sedimentation and re-coarsening of color pastes after storage, and noticeable color differences between batches. These pain points not only affect product quality but also lead to reduced production efficiency and higher costs.
Chemi Tech is well aware of these challenges and, drawing on in-depth research into pigment surface characteristics, has developed a series of high-efficiency dispersants for organic pigments. The core of our solution lies in precise molecular structure design, which can rapidly wet the pigment surface and, through strong anchoring groups and steric hindrance, stably disperse pigment particles in the system to prevent re-agglomeration.
The specific implementation steps are divided into four: the first is diagnostic analysis, where our technical team will understand your pigment system, resin medium, and process conditions; the second is product recommendation, matching the most suitable Chemi Tech dispersant grade for your system based on the analysis; the third is process optimization, providing specific suggestions on dosage and dispersion process parameters (such as speed and time); the fourth is effect verification, helping you evaluate the fineness, tinting strength, gloss, and storage stability after dispersion.
We once helped a coatings company solve the dispersion challenge of its phthalocyanine blue system. The customer's original formula suffered from weak color development, low gloss, and obvious re-coarsening after one week of storage. After technical evaluation by Chemi Tech, a polymer dispersant with a special block structure was recommended. After adjusting the dosage ratio and optimizing the grinding process, the fineness of the resulting color paste remained stable below one micron over the long term, the tinting strength increased by about 15%, the gloss was significantly improved, and after a three-month storage test there was no hard sedimentation and the fluidity remained excellent, successfully achieving a product upgrade.
Choosing Chemi Tech is not merely choosing a dispersant, but obtaining a complete solution that ensures stable and reliable pigment dispersion quality. We are committed to helping customers unlock the fullest potential of their pigments and enhance product competitiveness.
