1.Product Description
Achieve Brilliant, Heat-Stable Orange Coloration with Solvent Orange 60
-The Premium Perinone-Based Dye for Engineering Plastics and High-Performance Applications.
Solvent Orange 60, designated as C.I. 564100 and widely known as Macrolex Orange 3G, is a high-performance perinone-based solvent dye renowned for its exceptional heat resistance, outstanding lightfastness, and brilliant orange shade . This sophisticated dye features a unique 12H-phthaloperin-12-one molecular structure (a cyclic ketone dye) that delivers superior thermal stability and remarkable color strength in demanding polymer applications .
What distinguishes Solvent Orange 60 from conventional solvent dyes is its exceptional combination of heat resistance, lightfastness, and migration stability. With heat resistance up to 350°C in polycarbonate and 310°C in PET, this dye maintains its vibrant color through the most demanding injection molding, extrusion, and fiber spinning operations . Its lightfastness rating of 7-8 (on an 8-point scale) ensures long-lasting color integrity in outdoor and UV-exposed applications, making it the preferred choice for automotive components, consumer electronics, and eyewear .
