High-Performance Alternative to DISPERBYK-190 Dispersion Agent

The coating industry currently faces practical challenges including unstable supply of imported dispersants, prolonged procurement cycles, and persistently high costs. When seeking alternatives to DISPERBYK-190, manufacturers often encounter issues with poor compatibility, insufficient dispersion efficiency, or inadequate storage stability.

Chemi Tech addresses these pain points with the KMT-3009 series polymeric dispersant. Utilizing unique anchor-group design and molecular weight control technology, it effectively meets the wetting and stabilization requirements for organic/inorganic pigments. The product incorporates multi-polar functional groups that form strong bonds with pigment surfaces, while steric hindrance prevents pigment re-flocculation.

Implementation involves three key steps:

1. Sample compatibility testing: 100g trial samples for parallel comparison, focusing on color development, flocculation degree, and viscosity stability

2. Production parameter adjustment: Recommended dosage optimization (typically 0.2%-1.5% of formula) with appropriate grinding time adjustment

3. Batch verification: Storage stability validation through ≥3 production batches (40℃ accelerated testing for 28 days)

An industrial coatings manufacturer in Eastern China achieved consistent fineness of ≤15μm in black epoxy systems after implementation, with zero precipitation after 6 months of room temperature storage. Compared to the original imported solution, production costs were reduced by 22% and procurement cycles shortened from 8 weeks to 5 working days. Customers reported an 18% reduction in single-batch production time due to improved grinding efficiency.
