EFKA PX 4787
EFKA PX 4787
EFKA® PX 4787 is a solvent-based, reactive and a high-performance dispersant.
Pigment dispersants form an essential part of a pigmented coating formulation. Their use normally has a positive influence on properties such as grinding efficiency, colour development and transparency – but physical properties of the coating are often negatively impacted. EFKA PX 4787 changes this dynamic. When cross-linked with the main resin matrix, it can achieve excellent dispersing efficiency, while also significantly reducing the usual negative impact on coating properties, such as solvent resistance and hardness.
Features & Benefits
- Cross-linkable with NCO and melamine-based resin matrices for optimal hardness
- Exponentially lower pigment paste viscosity at lower addition levels
- Exceptional jetness for carbon black pigments
- Excellent gloss development
