Maintains thixotropic efficiency across a broad temperature range, minimizing viscosity fluctuations during transport.
Excellent compatibility with diverse resin chemistries, including two-component epoxies and chlorinated rubber.
Optimized particle size distribution ensures minimal impact on final film gloss and surface smoothness.
Reduces the need for high-shear dispersion during manufacturing, improving production efficiency and lowering energy costs.
Promotes uniform orientation of effect pigments for enhanced optical performance.

Спецификации

Технические особенности

Chemical Composition: A proprietary fatty acid modified polyamide wax pre-dispersed in a stabilized solvent carrier.
Non-Volatile Content: Maintains a solid concentration of 20% to 25% to facilitate easy volumetric dosing.
Activation Requirements: Formulated for low-temperature activation, generally effective between 30°C and 60°C.
Viscosity Profile: Imparts strong shear-thinning behavior, facilitating easy spraying while maintaining high rest viscosity.
Inter-coat Adhesion: Engineered to prevent surface migration, ensuring no negative impact on secondary coating layer adhesion.
Solvent Medium: Primarily dispersed in Xylene or Isopropyl alcohol to ensure rapid integration into solvent-borne industrial formulations.

Практическое применение в отраслях

Области применения

Marine and Protective Coatings: Ideal for high-build anti-corrosive primers and topcoats used in harsh maritime conditions.
Industrial Wood Finishes: Prevents pigment settling in solvent-based stains and high-solids lacquers without affecting film clarity.
Heavy-Duty Machinery: Utilized in agricultural and construction equipment finishes to ensure uniform thickness on complex geometries.
Automotive Refinish: Enhances the orientation of aluminum flakes and pearlescent pigments in metallic basecoats.
Epoxy Floor Coatings: Provides necessary thixotropy for self-leveling systems to prevent excessive flow during curing.
Sealants and Adhesives: Acts as a structural viscosity builder in moisture-cure polyurethane and specialized polysulfide formulations.
