Характеристики

Ключевые свойства и преимущества

  • Superior Substrate Wetting: Drastically reduces surface tension to ensure complete coverage on low-energy or poorly cleaned surfaces.
  • Defect Elimination: Effectively prevents the formation of craters, pinholes, and «fish eyes» during the application phase.
  • Enhanced Surface Slip: Improves the mar and scratch resistance of the dried film by providing a smooth, low-friction surface.
  • Excellent Compatibility: Maintains high transparency in clear coats without causing turbidity or decreasing the gloss levels.
  • Optimized Flow: Promotes a perfectly level finish, reducing orange peel and ensuring a high-quality «mirror-like» appearance in premium industrial coatings.
Спецификации

Технические особенности

  • Chemical Identity: Classified as a Polyether-modified Polydimethylsiloxane. (Note: 7331A is a trade designation; the core chemical is typically associated with CAS: 27306-78-1).
  • Active Concentration: Supplied as a 100% active matter concentrate, ensuring high efficiency at extremely low addition levels (0.1–1.0%).
  • Solubility Profile: Demonstrates excellent compatibility with aliphatic/aromatic hydrocarbons, esters, ketones, and water-reducible resin systems.
  • Thermal Stability: Exhibits robust temperature resistance, making it suitable for high-heat stoving enamels and coil coating processes.
  • Non-Ionic Nature: Ensures chemical stability across a wide pH range and prevents interference with various ionic pigments.
Практическое применение в отраслях

Области применения

  • Industrial Coatings: Vital for solvent-borne and water-borne primers and topcoats applied to metal machinery and structural steel.
  • Automotive Refinish: Used to achieve high-gloss, defect-free finishes on plastic bumpers and metal body panels where aesthetics are critical.
  • Wood Coatings: Enhances wetting on porous surfaces and improves the levelling of UV-curable furniture lacquers and stains.
  • Printing Inks: Optimizes the flow and substrate wetting of flexographic and gravure inks on filmic substrates and metallic foils.
  • Floor Coatings: Ensures smooth application of epoxy and polyurethane self-levelling systems, preventing surface irregularities over large commercial areas.
