Dyes And Pigments FAQ Common Questions
Q: What is the difference between dyes and pigments?
A: Dyes are soluble coloring substances that chemically bond to the substrate, while pigments are insoluble particles that require a binder to adhere to surfaces. Dyes typically offer more vibrant colors but may have lower lightfastness compared to pigments.
Q: How should I store Dyes And Pigments properly?
A: Store in cool, dry conditions away from direct sunlight. Keep containers tightly sealed to prevent moisture absorption. Maintain storage temperatures between 15-25°C. Organic pigments should be kept away from heat sources, while certain dyes may require refrigeration.
