Q1: What is the primary function of Clariant Polyglykol G 500 Pigment in formulations?
A: Clariant Polyglykol G 500 Pigment is a pigment preparation based on polyglycol technology, designed to provide stable coloration and enhanced dispersion performance in polar polymer systems—particularly in polyurethanes, polyesters, and water-based coatings. It combines pigment functionality with inherent compatibility and wetting assistance.
Q2: Is this product suitable for use in food-contact or pharmaceutical applications?
A: Clariant Polyglykol G 500 Pigment is not specifically developed or certified for direct food-contact or pharmaceutical use. Its suitability for regulated applications must be evaluated case-by-case, including full regulatory review of the final formulation and compliance with applicable local and regional requirements.
Q3: How should Polyglykol G 500 Pigment be incorporated into a polymer system?
A: It is typically added during the melt compounding or mixing stage, and benefits from moderate shear and elevated temperature to ensure uniform distribution. Pre-dispersion in a compatible carrier liquid or resin may further improve homogeneity, especially in high-viscosity systems.
Q4: Does this pigment require additional dispersing agents or stabilizers?
A: Due to its integrated polyglycol-based dispersant architecture, Clariant Polyglykol G 500 Pigment generally reduces or eliminates the need for supplemental dispersants in many standard formulations—though optimal performance may still depend on matrix polarity, processing conditions, and target color strength.
Q5: What are the recommended storage conditions?
A: Store in original sealed containers in a cool, dry place away from direct sunlight and sources of heat or moisture. Prolonged exposure to high humidity or temperature fluctuations may affect handling consistency and dispersion behavior.
