Характеристики

Ключевые свойства и преимущества

Drastic Viscosity Reduction: Enables significantly higher filler loadings without compromising flow or pumpability.
Superior Surface Wetting: Rapidly displaces air and moisture from the filler surface to ensure complete encapsulation.
Steric Stabilization: Prevents flocculation and particle settling during long-term storage or processing.
Improved Surface Finish: Eliminates surface defects and ‘orange peel’ effects by ensuring homogenous particle distribution.
Enhanced Throughput: Reduces mixing time and energy consumption by accelerating the wetting process.
Mechanical Optimization: Improves the tensile and impact strength of the final composite through better interfacial bonding.

Спецификации

Технические особенности

Functional Anchoring Groups: Designed with high affinity for mineral surfaces, including acidic and basic functional sites.
Low Volatility: High-solids or solvent-free liquid composition suitable for low-VOC industrial requirements.
Thermal Stability: Maintains chemical integrity at high processing temperatures (up to 250°C) without discoloration.
Broad Compatibility: Effective in various systems including unsaturated polyesters, epoxies, acrylics, and polyurethanes.
Dosage Efficiency: Highly concentrated formula requiring only 0.5% to 2.5% weight based on the filler content.
Hydrophobic Barrier: Provides a protective layer on fillers, reducing water absorption in the finished product.
