主要特点与优势

Enhanced Flop Index: Significantly increases the contrast between the highlight and shadow areas of metallic finishes.
Surface Uniformity: Effectively eliminates “silver clouding” and mottling by ensuring uniform pigment distribution during film shrinkage.
Adhesion Promotion: Does not negatively impact inter-coat adhesion or the integrity of the basecoat-clearcoat system.
Optimized Rheology: Provides specific viscosity control that prevents pigment settling and sagging without affecting gloss.
Process Efficiency: Reduces the need for multiple passes by achieving high-quality metallic effects in single-layer applications.
Long-term Stability: Improves the shelf-life of metallic pastes within liquid paint formulations.
Compatibility: Seamlessly integrates with low-VOC and traditional solvent-based resin matrices.

规格

技术亮点

Chemical Identity: Primarily composed of a modified polyethylene wax dispersion or specialty EVA-based copolymer.
Active Content: Typically supplied at an active concentration range of 5% to 15% to facilitate easy dosing.
Solvent Matrix: Commonly dispersed in Xylene, Butyl Acetate, or Aromatic 100 for rapid solvent evaporation.
Density: Specific gravity ranges between 0.85 and 0.92 g/cm³ at 25°C.
Thermal Stability: Effective at bake temperatures up to 160°C without yellowing or degradation.
Particle Size: Finely micronized particles ensure no visible graininess in high-gloss topcoats.
Recommended Dosage: Optimal performance achieved at 2.0% to 5.0% total formulation weight.
Appearance: Opaque, white to yellowish liquid.
