Pigment FAQ
What makes Pigment different from regular dyes?
Pigment consists of insoluble particles that remain suspended in the medium, unlike dyes which dissolve completely. This gives Pigment superior lightfastness and opacity, making it ideal for applications requiring long-term color stability. Pigment particles are typically 100-1000 times larger than dye molecules.
How should I store Pigment for maximum shelf life?
Store Pigment in airtight containers away from direct sunlight and moisture. Optimal storage conditions are temperatures between 10-25°C (50-77°F) with relative humidity below 65%. Properly stored, most Pigment formulations maintain stability for 5+ years without significant degradation.
Can Pigment be mixed across different product lines?
While Pigment can often be intermixed within the same chemical class (organic with organic, inorganic with inorganic), we recommend testing combinations first. Some Pigment formulations may interact differently based on their surface treatments, particle size distributions, and chemical compatibilities.

Application Guidelines
- Pre-disperse Pigment in appropriate wetting agents
- Gradually incorporate into base medium under agitation
- Maintain recommended processing temperatures
- Allow adequate milling time for optimal dispersion
- Test color development at multiple stages
Pigment Safety Information
While Pigment formulations are generally safe when handled properly, we recommend:
- Using NIOSH-approved dust masks during dry handling
- Wearing protective gloves to prevent skin irritation
- Ensuring adequate ventilation in processing areas
- Following all local regulations for pigment disposal
