What are the best UV-resistant pigments for outdoor PVC sculptures?

When creating outdoor PVC sculptures, choosing the right UV-resistant pigments is crucial to maintain vibrant colors and prevent fading under sunlight. The best pigments for this purpose include inorganic options like titanium dioxide and iron oxides, which offer excellent UV stability. Organic pigments with high lightfastness ratings, such as phthalocyanine blue and green, are also reliable choices. Additionally, specialty UV-stabilized colorants designed for PVC can enhance longevity. Always opt for pigments labeled as "lightfast" or "weatherproof" to ensure your sculptures remain vibrant for years. Properly mixed with PVC stabilizers, these pigments will withstand harsh outdoor conditions while retaining their aesthetic appeal.
