Waterborne Coatings Dispersion Challenges? Chemi Tech Dispersants Help You Overcome Pigment Agglomeration and Enhance Coating Performance

In the production and application of waterborne coatings, efficiently dispersing pigments is the crucial first step towards achieving a high-quality film. However, many manufacturers frequently face a series of challenges such as difficulty in wetting pigment particles, low grinding efficiency, re-coarsening and flocculation after storage, and failure to meet targets for film gloss and tinting strength. These pain points directly impact product consistency, production efficiency, and ultimately, market competitiveness.

Addressing these core needs, Chemi Tech, with its deep expertise in waterborne system additives, has developed a series of high-performance dispersant products. Our solution starts from understanding pigment surface characteristics and compatibility with waterborne systems. Through unique molecular structure design, we achieve efficient encapsulation and stabilization of both inorganic and organic pigments.

The implementation steps are clear and specific: First, our technical team assists clients in analyzing their pigment system and process conditions. Subsequently, we recommend suitable Chemi Tech dispersant types and determine the optimal addition point and dosage. During experimentation or production, this dispersant rapidly wets the pigment surface, reduces grinding energy consumption, and significantly shortens grinding time. Finally, the formed stable steric hindrance or electrostatic stabilization effectively prevents pigment particle re-agglomeration over the long term, ensuring consistent coating performance from production to the final application stage.

For instance, an enterprise in East China specializing in industrial coatings encountered issues of floating/flooding and viscosity increase after storage in a newly developed medium-gray topcoat. After adopting a designated polymeric dispersant from Chemi Tech, not only was the grinding time reduced by approximately 20% and the pigment paste stability greatly improved—showing no significant re-coarsening after three months of storage—but the final film's color uniformity, gloss, and weatherability also received high recognition from the client, successfully passing the strict acceptance criteria of their downstream users.

Choosing Chemi Tech is not just selecting a product; it is choosing a partner dedicated to enhancing the core performance of your coatings. We are committed to supporting your waterborne coatings projects with professional technical service and consistent product quality, making them more smooth and efficient, helping you gain a competitive edge in the market.
