Differentiated performance in waterborne pigment dispersions and universal colorants
Benefits in waterborne pigment dispersions
1. Excellent viscosity control at high pigment loadings
Rhodoline® 7500 helps formulations maintain low viscosity even at high pigment concentrations, making them easier to handle and process.
2. Efficient dispersion with reduced milling time
Rhodoline® 7500 delivers excellent dispersing efficiency, which can help reduce milling time while supporting strong and consistent color development.
3. Reliable, long-term dispersion stability
With Rhodoline® 7500, dispersions remain stable over time, maintaining consistent performance during storage and use, and providing peace of mind.
4. Improved color acceptance
Rhodoline® 7500 supports better color acceptance across different systems, which can make it easier to move from pigment concentrates to universal colorants and achieve consistent tinting results.
Benefits in waterborne universal colorants
1. Simplified wetting and dispersing package
Rhodoline® 7500 can reduce the need for multiple additives by combining wetting, dispersing and compatibility functions in one product, helping reduce formulation complexity and costs.
2. Consistent viscosity across pigment types
