Q1: What is the primary chemical class and typical hue profile of GRAPHTOL GR 13?
A: GRAPHTOL GR 13 is a high-performance quinacridone-based organic pigment, delivering a clean, bluish-red shade with excellent chroma and strong tinting strength in demanding applications.
Q2: Is GRAPHTOL GR 13 suitable for use in food-contact plastics?
A: GRAPHTOL GR 13 is designed for industrial and decorative applications and is not certified for direct food-contact use. Customers requiring food-safe pigments should consult Clariant’s dedicated food-contact compliant product portfolio and verify regulatory compliance with local authorities.
Q3: How does GRAPHTOL GR 13 perform under outdoor exposure and UV light?
A: Thanks to its robust quinacridone structure, GRAPHTOL GR 13 exhibits very good lightfastness and weather resistance—particularly when stabilized and properly dispersed in polymer systems such as polyolefins or engineering thermoplastics.
Q4: What are key handling considerations during processing?
A: As a fine organic pigment, GRAPHTOL GR 13 requires thorough dispersion to achieve optimal color development and performance. It is recommended to use high-shear mixing or compounding techniques and avoid excessive thermal stress during melt processing to preserve pigment integrity.
