FAQ
Q: What color does PR179 produce compared to other perylene reds?
A: PR179 produces a distinctly deeper, more maroon/bordeaux shade compared to the brighter reds of other perylene pigments, making it ideal for sophisticated, luxury applications.
Q: Is PR179 suitable for metallic systems?
A: While PR179 can be used in metallic systems, its opacity makes it more suitable for solid color applications. For metallic effects, consider our transparent perylene grades.
Q: What is the typical loading in automotive coatings?
A: Loading levels typically range from 1% to 8% depending on the desired color depth and film thickness. We provide specific formulation recommendations.
