Q1: What is the primary chemical composition and pigment class of Sicotan K2112FG?
A: Sicotan K2112FG is a high-performance inorganic pigment based on a modified titanium dioxide–silica composite system, engineered to deliver exceptional whiteness, brightness, and UV stability without relying on organic chromophores.
Q2: Is Sicotan K2112FG suitable for use in food-contact plastics?
A: Yes — Sicotan K2112FG is specifically designed and manufactured to meet stringent regulatory expectations for pigments in food-contact applications, including compliance with global frameworks for inert, non-leaching inorganic colorants. Final regulatory acceptance remains subject to full formulation assessment and applicable jurisdictional requirements.
Q3: How does Sicotan K2112FG perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability, maintaining color integrity and dispersion performance during standard polymer processing operations—including injection molding, extrusion, and blow molding—at temperatures commonly encountered in polyolefins, engineering thermoplastics, and PVC systems.
Q4: What are the recommended handling and dispersion practices for optimal performance?
A: For best results, pre-blend Sicotan K2112FG with the base polymer using high-shear mixing or masterbatch compounding. Its surface-treated morphology supports good wetting and dispersion in both polar and non-polar matrices, typically used at low concentrations where dosage depends on formulation requirements and desired opacity.
