Efka® PX 4787
Efka® PX 4787 is a high molecular weight dispersing agent designed to disperse and stabilize organic pigments and carbon-blacks. Use of Efka® PX 4787 results in significantly lower pigment paste viscosity without having to use high level of dispersant. Efka® PX 4787 is suitable for industrial and automotive coatings, especially where resin-matrix reactive dispersant is desired.
Performance Highlights
- Exponentially low pigment paste viscosities at lower addition levels
- Relatively consistent and stable viscosities over wide addition range
- Cross-linkable with -NCO- and melamine-based resin matrices for optimal durability
- Exceptional jetness for carbon black pigments
- Excellent gloss development
- Highest available transparency in CAB-containing systems
