Характеристики

Ключевые свойства и преимущества

Superior Thixotropy: Induces a pseudoplastic flow profile, ensuring excellent anti-sagging properties even in high-build coatings.
Anti-Settling Efficiency: Effectively prevents the hard-packing of dense pigments, metallic flakes, and extenders during prolonged storage periods.
Enhanced Leveling: Provides structural recovery that allows optimal surface flow before the viscosity increases, reducing brush marks significantly.
Broad Compatibility: Integrates easily with waterborne alkyds, acrylics, and PUDs without requiring high-temperature activation or complex pH adjustments.
Film Quality: Maintains excellent gloss retention and inter-coat adhesion, ensuring the mechanical integrity and aesthetic appeal of the cured film remains completely unaffected. This agent delivers high reliability for demanding industrial specifications.

Спецификации

Технические особенности

Chemical Composition: Pre-activated polyamide wax dispersion featuring a concentrated network of hydrogen-bonding active sites for structural reinforcement.
Shear Recovery: Exhibits rapid viscosity recovery post-application, critical for preventing edge-pull and sagging on complex vertical geometries.
Temperature Stability: Maintains rheological efficiency across variable processing temperatures, avoiding the viscosity drop-off common in conventional organoclays.
Low Dosage: High efficiency allows for significant performance at low addition levels (0.5%–2.0%), minimizing the impact on formulation costs.
Ease of Incorporation: Designed for post-addition or grinding stage integration, providing maximum flexibility during the manufacturing and formulation optimization process. The product meets stringent environmental standards while providing stable performance.

Практическое применение в отраслях

Области применения

Industrial Coatings: Essential for waterborne heavy-duty machinery coatings where high dry-film thickness and vertical stability are required.
Automotive Finishes: Used in metallic basecoats to ensure uniform orientation of aluminum flakes and prevent mottling or pigment floatation.
Wood Finishes: Provides sag resistance in thick-film furniture lacquers and joinery coatings, ensuring smooth edges and consistent film build.
Protective Primers: Enhances the stability of zinc-rich primers and anticorrosive coatings containing heavy mineral fillers or glass flakes.
Architectural Paints: Improves the application feel and anti-splatter properties of premium interior and exterior emulsion-based wall and ceiling paints. This additive is ideal for all water-based formulations.
