Q1: What is the primary chemical composition of Holliday Violet12/V12?
A: Holliday Violet12/V12 is a synthetic ultramarine pigment based on a complex sodium aluminosilicate matrix, with sulfur-containing chromophores responsible for its characteristic violet hue. It contains no heavy metals and is free from cadmium, lead, or chromium.
Q2: Is V12 suitable for use in polyolefin compounds such as PP and HDPE?
A: Yes — Holliday Violet12/V12 exhibits excellent thermal stability and dispersibility in polyolefins. It maintains color integrity during standard extrusion and injection molding processes, and shows minimal plate-out tendency under typical processing conditions.
Q3: How does V12 perform in alkaline environments, such as cementitious systems or high-pH coatings?
A: As an ultramarine-based pigment, V12 demonstrates good resistance to alkaline media and is commonly used in architectural coatings, stucco, and dry-mix mortars where pH values exceed 10. However, prolonged exposure to strong acids or highly reducing conditions may affect hue stability.
Q4: Can V12 be used in food-contact plastics?
A: Holliday Violet12/V12 is not certified for direct food-contact applications under current global regulatory frameworks. While it meets general safety requirements for industrial plastics, formal food-contact compliance requires specific migration testing and regulatory review per jurisdiction and end-use conditions.
