Характеристики

Ключевые свойства и преимущества

Exceptional Anti-Settling: Provides superior suspension for heavy pigments and metallic flakes, preventing dense sedimentation during storage.
Superior Sag Resistance: Enables thick coatings on vertical surfaces without dripping, maintaining excellent film integrity and edge coverage.
Optimized Rheology: Imparts strong thixotropic behavior, ensuring high low-shear viscosity for stability and excellent flow under high-shear application.
Gloss Retention: Minimizes impact on surface gloss and transparency, making it ideal for clear coats and high-gloss finishes.
Easy Incorporation: Pre-activated liquid form allows simple post-addition under low-shear mixing without requiring heat or specific activation temperatures during processing.

Спецификации

Технические особенности

Chemical Composition: Modified polyamide wax dispersion in a water/surfactant matrix, ensuring high compatibility with polar water-borne resin systems.
Activation Profile: Fully pre-dispersed and pre-activated, eliminating the narrow temperature windows required by traditional organic thixotropes during paint manufacturing.
pH Stability: Demonstrates robust performance across a broad pH range (7.0–10.0), common in most commercial water-borne industrial formulations.
Hydrogen Bonding Network: Establishes a reversible physical gel structure that recovers rapidly after shear removal, enhancing structure recovery time.
Compatibility: Highly effective in acrylic, epoxy, polyurethane, and alkyd dispersions without causing seeding, flocculation, or surface defects.

Практическое применение в отраслях

Области применения

Automotive Coatings: Ideal for water-borne basecoats and primers to ensure uniform orientation of metallic pigments and aluminum flakes.
Industrial Finishes: Used in heavy-duty machinery coatings and protective finishes where vertical film thickness and sag control are critical.
Architectural Paints: Enhances the application properties of premium interior and exterior latex paints, reducing spatter and improving brush-loading.
Wood Coatings: Provides rheological control for water-based stains and lacquers, preventing pigment settling in low-viscosity, deep-penetrating wood formulations.
Inks and Adhesives: Optimizes the viscosity of water-based flexographic inks and structural adhesives for improved transfer and bond stability.
