Evonik structures technical service around measurable formulation questions: target viscosity, substrate wetting, dispersion stability, HPLC or GC purity, solids content, and regional regulatory documentation. Our team helps procurement, R&D, and quality groups move from candidate chemistry to controlled trials without relying on generic performance claims.
We compare additive packages against defined substrates, solvent systems, pH windows, and storage conditions. Results are documented with method references such as ASTM D2196 viscosity, ASTM D2369 non-volatile content, or HPLC assay where relevant.
Pilot batches focus on process transfer: feed order, shear profile, temperature hold, filtration, and packaging compatibility. Each review includes EHSS notes and SDS handling references for the selected chemistry.
Before launch, teams align regional documents, change-control expectations, lead-time assumptions, and sample retains so supply and quality groups can approve the material with fewer late-stage surprises.
Clarify market, substrate, annual volume, and required documentation.
Shortlist chemistries by performance target, region, and handling profile.
Run viscosity, dispersion, compatibility, and stability checks.
Confirm GHS classification and transportation constraints.
Validate processing window and packaging readiness.
Document lead time, quality release, and change control.
The lab program is designed for formulators who need transparent data rather than broad claims. Typical work packages include rheology curves, compatibility matrices, accelerated storage, residual solvent review, and SDS-linked hazard assessment. For regulated markets, we identify which data can support customer dossiers and which claims require end-use validation by the finished-goods manufacturer.
| Capability | Typical method | Decision supported |
|---|---|---|
| Viscosity and flow | ASTM D2196 / ISO 2555 | Processing window and pumpability |
| Purity profile | HPLC or GC assay | Batch acceptance and impurity trend |
| Moisture | Karl Fischer titration | Hydrolysis risk and packaging control |
| Particle size | Laser diffraction D50/D90 | Dispersion stability and filtration |
Include target application, region, annual volume, known restrictions, and any required test method. A specialist will respond with the relevant document path and recommended next step.
