Stability of TiO₂ Formulations:
Ensuring Dispersion, Compatibility & Performance
Technical formulations containing titanium dioxide require a deep understanding of the dispersion state – whether in pastes, paints, or functional dispersions. We support you in targeted stabilization and performance optimization of your systems.
Stability and Suitability of TiO₂ Pigments in Application Systems
Titanium dioxide pigments vary significantly in their processing characteristics and their impact on the pigmented system – depending on the specific type. Even basic parameters such as brightness, undertone, gloss, and dispersibility play a crucial role during the initial selection process.
But there is no such thing as “the best TiO₂ pigment.” What matters is finding the one that best fits your specific application.
What We Measure
In highly concentrated technical dispersion systems for paints and coatings, we analyze:
-
Electrostatic charge of the pigment surface
-
Flocculation behavior and isoelectric point (IEP)
-
Adsorption characteristics of additives
-
Reaction behavior depending on additive type and dosage
These measurement results provide valuable insights into the real behavior of a TiO₂ pigment formulation – under the exact conditions relevant to its final application.
Targeted Stability Adjustment
To produce stable TiO₂ pigment dispersions, we investigate the effects of additives. Key findings include:
-
Depending on the dosage, stabilization occurs via electrostatic, steric, or combined mechanisms
-
The decisive factor is the degree of pigment surface coverage by the additive
-
Modern electroacoustic measurement techniques detect changes directly in the dispersion
-
This allows us to determine the optimal additive levels for various pigment types – whether for highly viscous pastes or smoothly flowing systems.
Formulation Screening and Stability Optimization for TiO₂-Based Systems
Rapid Identification of the Right Pigment
We offer fast, application-oriented screening of suitable TiO₂ pigment types for your specific formulation needs. This allows you to make confident decisions before scaling up to pilot or production levels.
Controlling the Stabilization Process
We analyze and optimize the stabilization behavior of TiO₂ pigment dispersions, focusing on both electrostatic and steric mechanisms.
Our services include:
-
Full screening of the electro-steric stabilization balance
-
Precise and reproducible adjustment of stabilization parameters
-
Monitoring and fine-tuning under laboratory conditions
-
Generation of scalable results for pilot plant and production use
Additives & Fillers: Interaction Matters
Functional fillers often have specific surface properties, especially when surface-treated. For optimal formulation performance, these must be compatible with the surface chemistry of the TiO₂ pigment.
We determine the optimal pH windows and formulation parameters to ensure stable and effective pigment–filler interactions – resulting in high-performance coating systems.
Your Advantage
You receive a technically validated formulation strategy that ensures dispersion stability, can be tailored to flow or viscosity requirements, and is ready to scale for production.
