4340A Orienting Agent is a high-performance chemical additive specifically engineered to optimize the spatial distribution and alignment of metallic and pearlescent pigments within liquid coating s…
Superior Pigment Orientation: Facilitates precise parallel alignment of aluminum flakes, enhancing the metallic luster and depth of the finish.
Mottling Prevention: Eliminates visual inconsistencies like “tiger striping” or cloudiness by stabilizing the pigment distribution during the drying phase.
Enhanced Color Travel: Maximizes the “flip-flop” effect, providing distinct color shifts at different viewing angles for premium aesthetics.
Anti-Settling Properties: Provides excellent suspension stability for heavy metallic pigments, preventing hard-packed sediment during storage.
Inter-coat Adhesion: Engineered to maintain high compatibility, ensuring that subsequent clearcoat layers adhere perfectly without delamination or surface tension issues.
规格
技术亮点
Chemical Basis: High-molecular-weight Ethylene-Vinyl Acetate (EVA) copolymer dispersion optimized for solvent-borne systems.
Active Solid Content: Typically supplied at a concentration of 6.0% to 10.0%, ensuring efficient delivery of the orienting micro-wax.
Solvent Compatibility: Primarily dispersed in aromatic hydrocarbons (like Xylene) or acetate esters for rapid integration into paint formulations.
Micro-particle Geometry: Features controlled particle size distribution to ensure optical transparency in the final film without affecting gloss.
Dosage Efficiency: Highly effective at low addition levels, generally ranging from 10% to 30% on total formulation weight depending on pigment load.
