Характеристики

Ключевые свойства и преимущества

Superior Surface Tension Reduction: Drastically lowers dynamic surface tension to ensure complete substrate wetting and penetration.
Enhanced Leveling: Promotes rapid flow-out, eliminating surface imperfections like orange peel and brush marks effectively.
Anti-Crater Properties: Effectively prevents defects caused by contaminants or low-energy spots on various technical substrates.
Excellent Compatibility: Suitable for water-based, solvent-based, and UV-curable systems without causing film turbidity or haze.
Improved Slip: Enhances surface smoothness and scratch resistance of the dried film for better mechanical durability.
Minimal Foaming: Optimized molecular structure ensures high efficiency with low air entrainment during application.
Recoatability: Maintains inter-coat adhesion, allowing for multiple applications without requiring intensive surface sanding.

Спецификации

Технические особенности

Chemical Composition: High-purity polyether-modified polydimethylsiloxane copolymer designed for maximum surface activity and stability.
Active Content: Typically provided at 100% concentration for maximum formulation flexibility and overall cost-effectiveness.
Solubility Profile: Fully soluble in water, alcohols, and organic solvents like aromatics, glycols, and esters.
Thermal Stability: Maintains performance integrity across a wide temperature range, making it suitable for stoving enamels.
pH Versatility: Exhibits stable performance in both acidic and alkaline environments ranging from pH 4 to 10.
Viscosity: Low-viscosity liquid (200–500 mPa.s) ensuring easy incorporation and uniform distribution within the matrix.
Dosage Efficiency: Effective at low addition levels, typically 0.1% to 1.0% based on total formulation weight.

Практическое применение в отраслях

Области применения

Automotive Coatings: Used in basecoats and clearcoats to achieve a mirror-like, high-gloss finish and depth.
Industrial Wood Finishes: Improves wetting on porous wood surfaces and prevents cratering over residual natural resins.
Printing Inks: Enhances dot gain and flow in high-speed flexographic, gravure, and screen-printing ink applications.
Waterborne Paints: Essential for reducing surface tension in latex systems to prevent crawling on plastic substrates.
UV-Curable Coatings: Provides rapid wetting and leveling during high-speed curing processes in electronics and packaging.
Protective Metal Coatings: Ensures uniform coverage over oily or poorly prepped metal substrates in industrial maintenance.
Leather Finishing: Enhances the surface feel and uniformity of topcoats on treated synthetic and natural leather.
