Dispersion & colloids
Surface charge, adsorption and steric hindrance decide whether a dispersion stays stable.
- Key variables
- Solids, pH, addition sequence, shear history
- Observables
- Particle size, zeta potential, settling and storage stability
Approach
Every project moves along the same chain: material interfaces, formulation design, process fit and application evaluation. We write down the variables, methods and pass criteria at each step, so conclusions can be checked and scaled.
Four control domains
Battery slurries, adhesives or functional coatings — problems end up in one of these four control domains.
Surface charge, adsorption and steric hindrance decide whether a dispersion stays stable.
Wetting, contact and chemical interaction between binder and particles, collectors or substrates.
Viscosity, thixotropy and recovery under shear set the coating window.
Solvent migration, film-forming temperature and cross-linking during drying set the final structure.
Five-stage method
Each stage ends at a gate: continue, adjust or stop — decided by data.
Four-layer evaluation
No single metric defines a scalable system. Evaluation follows the conditions and methods agreed for each project, with clear data ownership and full traceability.
How we work together
Application, material system and current issue — no confidential information needed.
Sign an NDA as the project requires and write the brief and metrics together.
Agree candidate routes, reference design and sample arrangements.
Evaluate under agreed conditions, review the data and decide the next step.
Define scale-up conditions and batch control, then move to the next scale.
Deliverables
It takes three minutes, and we set up the technical conversation from there.
