In the production and application of waterborne coatings, efficiently dispersing pigments is the crucial first step toward achieving a high-quality film. However, many manufacturers face a series of challenges, including pigment particles that are difficult to wet, low grinding efficiency, re-agglomeration and flocculation after storage, and substandard film gloss and tinting strength. These pain points directly affect product consistency, production efficiency, and ultimately market competitiveness.
To meet these core needs, Chemi Tech has deep expertise in waterborne-system additives and has developed a series of high-performance dispersants. Our solution starts from understanding the surface characteristics of pigments and their compatibility with waterborne systems, using unique molecular structure design to achieve efficient encapsulation and stabilization of both inorganic and organic pigments.
The implementation steps are clear and well defined. First, our technical team assists customers in analyzing the pigment system and process conditions in use. Next, we recommend a suitable Chemi Tech dispersant grade and determine the optimal addition point and dosage. During trials or production, the dispersant quickly wets the pigment surface, reduces grinding energy consumption, and significantly shortens grinding time. Finally, the resulting steric hindrance or electrostatic stabilization prevents pigment particles from re-agglomerating over the long term, ensuring consistent performance from production through end application.
For example, a company in East China specializing in industrial coating encountered problems of floating and flooding as well as rising viscosity after storage in a newly developed medium-gray topcoat. After adopting the Chemi Tech-recommended polymeric dispersant, grinding time was reduced by about 20% and paste stability improved substantially, with no significant re-agglomeration after three months of storage. Moreover, the color uniformity, gloss, and weather resistance of the final film were highly praised by the customer, and it successfully passed the strict acceptance of its downstream users.
Choosing Chemi Tech means choosing not only a product, but a partner focused on enhancing the core performance of your coatings. We are committed to helping you make your waterborne coating projects smoother and more efficient through professional technical service and stable product quality, gaining a market edge.
