Характеристики

Ключевые свойства и преимущества

Dramatic Surface Tension Reduction: Lowers equilibrium and dynamic surface tension to ensure complete wetting on difficult, low-energy substrates like PE or PP.
Anti-Crater Efficacy: Prevents surface defects such as craters, fish-eyes, and pinholes caused by substrate contamination or low-surface-energy impurities.
Minimal Foam Influence: Unlike traditional surfactants, it provides robust wetting without significantly increasing air entrainment or stabilizing micro-foam during application.
Enhanced Flow and Leveling: Facilitates smooth film formation, improving the final gloss and DOI (Distinction of Image) of the coating.
Excellent Recoatability: Maintains inter-coat adhesion, ensuring no adverse effects on subsequent layers or topcoats in multi-layered finishing and painting processes.

Спецификации

Технические особенности

Chemical Composition: Polyether-modified siloxane copolymer designed for maximum organo-functional efficiency in aqueous environments and complex formulations.
Physical Form: Clear to slightly hazy liquid, facilitating easy incorporation into both let-down and grinding manufacturing phases.
Active Substance Content: 100% active matter, ensuring high concentration, reduced logistics costs, and maximum cost-effectiveness for industrial-scale manufacturing.
Solubility Profile: Fully dispersible in water and highly compatible with common co-solvents like glycol ethers and alcohols.
Effective Dosage: Recommended addition levels between 0.1% and 1.0% based on total formulation weight for optimal performance.
Thermal Stability: Maintains chemical integrity across broad temperature ranges during industrial curing, baking, and storage cycles.

Практическое применение в отраслях

Области применения

Waterborne Industrial Coatings: Essential for metal and plastic coatings where substrate wetting on oily or hydrophobic surfaces is a priority.
High-Performance Printing Inks: Optimized for flexographic and gravure inks, ensuring sharp image definition and uniform coverage on non-porous films.
Wood and Furniture Finishes: Provides deep penetration and uniform leveling on porous wood substrates, preventing «crawling» over oily or resinous surface sections.
Overprint Varnishes (OPVs): Enhances the wetting properties of clear coats over dried ink layers without compromising transparency or gloss.
Pressure-Sensitive Adhesives (PSAs): Improves the coating consistency of water-based adhesives on release liners and various plastic carrier films for industrial tapes.
