Chemi Tech Oil-Based Dispersants: Professional Solution for High-Viscosity System Dispersion Challenges

In the production of oil-based coatings, inks, and high-performance composite materials, do you often encounter these frustrations? Pigments or fillers are difficult to disperse evenly in the resin system, leading to low grinding efficiency. The product develops hard settlement after storage that cannot be re-dispersed. The coating exhibits uneven gloss or floating and flooding, compromising final appearance and performance. The core of these issues often lies in the failure of the dispersion process.

Chemi Tech understands that achieving long-term, stable, and uniform dispersion in high-viscosity, high-solids oil-based systems is a critical challenge. Traditional dispersion methods or general-purpose additives struggle to meet the simultaneous demands of rapid wetting, powerful de-agglomeration, and long-term stability. To address this, we have developed a series of professional oil-based dispersants, providing a complete solution from problem diagnosis to resolution.

Our solution follows a clear action plan. The first step is accurate diagnosis and selection. Our technical team analyzes your system composition, process conditions, and specific issues to recommend dispersant types with suitable anchoring groups and solvated chains, ensuring compatibility with your resin system.

The second step is optimizing addition and dispersion process. We recommend pre-mixing the dispersant with pigments and part of the resin before grinding to ensure thorough wetting of pigment surfaces, reducing the strength of agglomerates at the source. During the grinding stage, the dispersant effectively reduces paste viscosity, improving grinding efficiency and shortening processing time.

The third step is achieving long-term stability. Chemi Tech dispersants form a strong and thick protective layer on pigment particle surfaces through steric hindrance and electrostatic stabilization mechanisms. This effectively prevents particles from re-agglomerating due to van der Waals forces, thereby preventing re-coarsening, settling, and performance degradation during storage.

A case from the industrial coatings sector demonstrates the value of this solution. A client producing dark anti-corrosion coatings could not resolve carbon black dispersion issues, resulting in fluctuating gloss and substandard anti-corrosion performance. After adopting a specific high-molecular-weight block copolymer dispersant from Chemi Tech, the carbon black was fully dispersed. Grinding time was reduced by approximately 30%. The resulting coating showed consistent gloss, and no hard settlement occurred after prolonged accelerated storage testing. The coating's salt spray resistance also improved significantly due to uniform pigment distribution.

Choosing Chemi Tech means selecting not just a product, but a reliable dispersion strategy for high-viscosity oil-based systems. We are committed to supporting your product quality enhancement, production process stabilization, and market competitiveness with professional chemicals and technical services.
