The 6090 block copolymer dispersant represents a pinnacle in high-performance additive technology, specifically engineered for the stabilization of organic and inorganic pigments in high-solids sol…
Enhanced Optical Properties: Delivers superior gloss levels and image clarity while eliminating haze in high-performance solvent-borne finishes.
Exceptional Pigment Stabilization: Prevents re-flocculation and settling through robust steric hindrance, ensuring long-term shelf stability and color consistency.
Optimized Color Development: Improves tinting strength and coloristic properties of high-value organic pigments, particularly carbon blacks and phthalocyanines.
Broad Compatibility: Exhibits excellent solubility across a wide range of resin systems, including acrylics, polyesters, and epoxies, without affecting inter-coat adhesion performance or the final film integrity and weather resistance levels.
规格
技术亮点
Chemical Composition: High molecular weight modified acrylic block copolymer designed via controlled radical polymerization (CRP) for architectural precision.
Active Substance Content: Formulated as a 40–50% active solution in methoxypropyl acetate (PMA) or similar high-solvency esters.
Amine Value: Features a controlled amine value (approx. 10–20 mg KOH/g), facilitating strong anchoring to acidic pigment surfaces.
Non-Volatile Matter: High solids delivery ensures minimal VOC contribution relative to performance, maintaining compliance with modern environmental standards.
Structural Architecture: Tailored A-B block distribution provides a clear distinction between the anchoring segment and the solvating stabilizing tail for maximum efficiency across diverse polar and non-polar solvent matrix.
实际行业应用
应用领域
Automotive Coatings: Ideal for OEM and refinish systems where high gloss, excellent transparency, and superior color depth are mandatory.
Industrial Finishes: Utilized in high-performance protective coatings, providing stable dispersions for anti-corrosive pigments and heavy-duty industrial primer applications.
Carbon Black Dispersions: Specifically optimized for dispersing high-surface-area carbon blacks, preventing “seeding” and ensuring jet-blackness in premium topcoats.
Wood Coatings: Enhances clarity and grain definition in solvent-borne wood stains and clear coats by maintaining ultra-fine pigment particle size.
High-End Inkjet Inks: Serves as a stabilizer in solvent-based inkjet formulations, ensuring low viscosity and nozzle reliability for industrial printing processes involving complex pigment chemistries.
