How to Evaluate a Titanium Dioxide Sample
Evaluate a titanium dioxide sample against a named current grade in the same formulation, equipment and process window. Record sample identity, batch, document version, addition rate, dispersion conditions and agreed outcome measures, then repeat promising results at production scale before approving a commercial change.
Scope: This is general guidance; product-specific facts require an approved exact-grade source.
Last reviewed: 30 July 2026
Controlled titanium dioxide trial sequence
- Define the baseline. Name the current product, formulation, loading and current result.
- Set acceptance criteria. Choose only the optical, dispersion, processing and end-use outcomes that matter to the project.
- Confirm sample identity. Record the exact grade, sample or batch reference and available product-document version.
- Hold variables constant. Keep formulation, addition order, equipment, time, temperature and application or conversion conditions comparable.
- Record results. Use the same method, units and sample preparation for the baseline and candidate.
- Investigate differences. Do not change several variables at once to force a preferred result.
- Confirm at production scale. Repeat an acceptable laboratory result on the intended line before purchase approval.
Application-specific sample evaluation matrix
The items below are possible evaluation fields, not universal specifications or guaranteed outcomes. Select only the observations and methods appropriate to the customer's product, process and acceptance criteria.
| Application | Baseline information | Possible comparison fields | Production confirmation |
|---|---|---|---|
| Coatings | Binder system, carrier, PVC direction, dispersion method, film preparation and current pigment. | Opacity, whiteness, undertone, tinting, gloss, viscosity, finish and exposure observations as relevant. | Use the intended mixing, application, drying or curing conditions. |
| Plastics and masterbatch | Polymer, additives, loading or dilution, equipment, temperature profile and current pigment. | Dispersion, opacity, whiteness, undertone, surface appearance and processing observations as relevant. | Run the intended compounding and conversion route using recorded conditions. |
| Ink | Resin and solvent system, pigment loading, dispersion method, print process and current pigment. | Dispersion, viscosity, opacity, whiteness, print appearance and process behaviour as relevant. | Confirm on the intended ink-making and printing equipment. |
| Paper | Furnish or coating system, addition point, dispersion method, basis or coat-weight direction and current pigment. | Brightness, opacity, shade, dispersion and process observations as relevant. | Confirm under the intended paper-making or coating conditions. |
Minimum sample record
- Exact candidate name, sample or batch reference and date received
- Current TDS version and any other reviewed documents
- Named baseline product and reason for the comparison
- Formulation, raw-material lots and addition sequence
- Equipment, speed, time, temperature and other process settings
- Test method, units, specimens and acceptance criteria
- Operator, date, observations, deviations and photographs where useful
- Decision: reject, repeat, adjust the controlled plan or proceed to production confirmation

Choose an ApplicationTitanium dioxide sample evaluation questions
Should a TiO2 sample be tested without a named baseline?
A named baseline is strongly preferred because it establishes the current formulation, loading, process and result. Without it, differences are harder to interpret and repeat.
Can a laboratory TiO2 result approve a commercial change?
No laboratory result guarantees production performance. A promising result should be repeated and confirmed under the intended production-line conditions before purchase approval.
What documents should be tied to the sample record?
Record the exact sample identity and current TDS version. Note any SDS, COA or other documents reviewed, but confirm their applicability to the selected product and transaction separately.
Request a qualified titanium dioxide sample
Provide the application, current grade, formulation or process context, target result and planned trial method so the sample request can be reviewed.
