DISPEX Ultra PX 4585
DISPEX Ultra PX 4585
DISPEX ® Ultra PX 4585 is a water-based dispersant of the acrylic block copolymer family of products made by Controlled Free Radical Polymerization (CFRP). This technology allows formulating polymeric dispersants with defined polymer architecture and a low poly-dispersity index. This material is especially suited for the dispersion of pigments in water-based coatings.
DISPEX Ultra PX 4585 offers high efficiency in stabilizing pigments and demonstrates wide compatibility with many water-based resin systems. This makes it ideally suited for the use of the concept of resin-free pigment concentrates (RFPC).
It can be used in the following applications:
- for organic and inorganic pigments
- in resin-free pigment concentrations (RFPC)
- in resin mineral pigment concentrates (RMPC)
- for water-based architectural in-plant tinters
- in broad pH ranges during the grinding and let-down phases
Features & Benefits
- Excellent jetness for carbon black pigments
- Benchmark performance for carbon black and organic pigments
- Strong viscosity reduction in high pigment concentration in the grinding stage
- Improved pigment affinity and stability
- Particularly recommended where high transparency is required
- Broad compatibility in water borne systems
Sustainability Highlights
- VOC-free according to EU 2004/42 method
- APEO-free
- Low odor
