Характеристики

Ключевые свойства и преимущества

Superior Levelling Performance: Drastically reduces «orange peel» effects and surface waviness by evening out surface tension gradients.
Non-Silicone Composition: Eliminates risks of intercoat adhesion failure and allows for easy overpainting or recoating without intensive sanding.
Clarity and Gloss: Enhances the Depth of Image (DOI) and maintains high transparency in clearcoat applications without haze.
Broad Compatibility: Demonstrates excellent solubility in a wide range of polar and non-polar solvent-borne resin systems.
Defoaming Synergy: Assists in the release of micro-bubbles and prevents pinholing during high-speed application processes.
Thermal Stability: Maintains functional integrity during high-temperature industrial baking cycles.

Спецификации

Технические особенности

Chemical Nature: Solution of a modified polyacrylate polymer.
Active Content: Formulated at 50% to 70% non-volatile matter in aromatic or ester-based solvent carriers.
Refractive Index: Precision-matched to standard resin systems to ensure optical purity in high-gloss topcoats.
Density: Approximately 0.95–1.05 g/cm³ at 25°C, allowing for rapid and uniform incorporation.
Low Acid Value: Typically <3 mg KOH/g, ensuring zero interference with acid-catalyzed curing mechanisms or metallic pigments.
Effective Dosage: Highly efficient at concentrations between 0.1% and 1.0% based on total formulation weight.
Appearance: Clear to slightly yellowish liquid.
