Global manufacturers depend on reliable, high-performance pigments for their production processes. Titanium Dioxide (Tioxin) is the primary pigment used for most paints, coatings, plastics, inks, and chemical products. To ensure products are reliable and a consistent process, global buyers require extensive performance studies.
In this guide, we will detail how you can conduct a performance evaluation of Titanium Dioxide (Tioxin) with internationally accepted standards.
Why Titanium Dioxide Performance Testing Is Important for International Buyers
When you’re sourcing titanium dioxide (Tioxin) for export or big manufacturing projects, even tiny differences in quality can mess with your final product. You might see color shifts from batch to batch, end up using more pigment than expected, or struggle to get the coverage you need. All of that just drives up your production costs.
That’s why a solid titanium dioxide performance test matters. To determine the correct grade of the product whenever we ship it to an international market, this quality assurance system aligns the business with international quality requirements. Consequently, if the business exports to more than one international market, it is imperative that you get quality testing right. For companies like Sukhmani Impex, sticking to consistent titanium dioxide performance test practices is vital to meet standards across Asia, Europe, the Middle East, Africa, and the Americas.
Key Parameters Evaluated in a Titanium Dioxide Performance Test
The Titanium Dioxide performance test has been structured to examine every attribute outlined below. Each factor shows the efficiency of titanium dioxide when used under standard application scenarios and is derived from globally accepted quality assurance standards.
- Brightness and whiteness.
- Opacity, visibility and hiding abilities.
- Tinting strength of titanium dioxide (Tioxin).
- Decolourising effect of titanium dioxide (Tioxin) .
- Size and distribution of particles.
- Ability to disperse.
1. Testing the Tinting Strength of Titanium Dioxide
What Is the Tinting Strength of Titanium Dioxide?
Titanium dioxide has a tinting strength which represents the extent to which a dark colour will look lighter when mixed with this pigment. A pigment with a higher tint intensity allows the manufacturer to use less pigment to create the same shade of color, thus making the manufacturer’s bottom line better and giving consistent colour.
International Testing Procedure for Tinting Strength of Titanium Dioxide
- The data obtained from the tests is subsequently compared to the accepted industry standard globally.
- A combination of titanium dioxide (Tioxin) and a conventional pigment in black is tested at a predetermined ratio.
- The combined formulation is milled under controlled conditions to achieve proper dispersion.
- A professional spectrophotometer is utilised to measure the colour intensity of the finished product.
- The data obtained from the tests is subsequently compared to the accepted industry standard globally.
Why Tinting Strength of Titanium Dioxide Matters in Global Supply Chains
Titanium dioxide as a colour additive gives manufacturers many advantages.
Some of these advantages are:
- Colour consistency across the production process.
- Increased formulation efficiency.
For those in the coating, plastic, and paint industries, the tint strength of Titanium Dioxide (Tioxin) will be an indicator of how their products will perform.
2. Testing the Decolourising Power of Titanium Dioxide
Understanding the Decolourising Power of Titanium Dioxide
The decolourising power of titanium dioxide is all about how well it wipes out unwanted colour in different products. You’ll see this come up a lot in things like detergents and polymers.
Here’s how people usually test it:
First, they prepare a colored solution—methylene blue is often used. Next, they add a fixed amount of titanium dioxide. Finally, the mixture is stirred under controlled conditions. A change in color of the solution is used to quantify how well a pigment removes color. The more color removed the better the performance of that pigment and the more reproducible it is.
When evaluating potential suppliers of titanium dioxide, many companies will evaluate them based on the consistency in decolorizing power of their titanium dioxide products.
3. Titanium Dioxide Quality Test Methods Used Globally
International manufacturers rely on standardised titanium dioxide quality test methods to verify pigment consistency and application suitability.
Universal Quality Testing Methods for Titanium Dioxide
X-Ray Diffraction (XRD) – used to determine if a titanium dioxide sample is rutile or anatase.
Scanning Electron Microscopy (SEM) – used to study the morphology of titanium dioxide particles.
Laser Particle Size Analysis – used to identify the particle size distribution of titanium dioxide.
Oil Absorption Value (OAV) – used to evaluate the structure of TiO₂ particles.
Loss on Ignition (LOI) – measures water and volatile matter in titanium dioxide pigment, which provides an accurate indication of the quality in terms of the technical required specifications.
Worldwide, quality control laboratories are utilizing these titanium dioxide testing methods to ensure quality and compliance with internationally accepted standards.
4. How to Test Titanium Dioxide for Whiteness and Opacity
The knowledge of testing the visual properties of titanium dioxide is essential for purchasers to make the right decision regarding the grade of TiO₂ to be used in high-end applications.
Whiteness Testing of Titanium Dioxide
Let’s talk about measuring the whiteness of titanium dioxide. The reflectance of titanium dioxide is generally determined by using reflectance spectrophotometry. In reflectance spectrophotometry, the amount of light reflected from the surface of a TiO₂ sample is measured after it is exposed to a controlled light source and these measurements will tell how bright and visually quality the titanium dioxide is and will help to ensure that the performance of the titanium dioxide in downstream applications is consistent.
Key Points:
- Use a controlled light source to obtain data on the TiO₂ sample.
- Measure light reflectance using defined wavelength standards.
- Utilising calibrated spectrophotometers to provide accurate results.
- Comparing values with a standard white reference .
- Higher reflectance indicates a brighter and whiter appearance.
- Will provide consistent pigment quality and performance.
Opacity and Hiding Power Testing of Titanium Dioxide
Here’s what happens:
To determine how well the pigment covers what is under it, we can determine how much light is reflected from the coated surface. Once we have that number, we can calculate the contrast ratio between the surface of an object and the underlying substrate.
These methods are common within the industry for evaluating the performance of titanium dioxide quality test methods over the coating and plastics industries.
5. Dispersion Quality Testing of Titanium Dioxide
Dispersion quality has a significant influence on the visual aspects of the final product, such as gloss, surface smoothness, opacity, and color uniformity. One may go even so far as to say that the highest grade titanium dioxide pigments will hardly live up to their expectations if they are not properly dispersed in the formulation.
Testing Procedure:
Simply put, the first step in checking dispersion quality is mixing titanium dioxide into a standard base formulation under controlled conditions. The pigment is dispersed to determine the shear forces and mixing times that would simulate a real production environment. The resulting dispersion is then evaluated using one or more of the following methods:
- Hegman gauge testing to measure particle agglomeration and grind quality.
- Gloss and drawdown tests to evaluate surface smoothness and appearance.
- Microscopic examination to identify undispersed particles or clusters.
- Colour uniformity analysis to check for streaking or shade variation.
These dispersion tests are a necessary step in the confirmation of the most efficient and even distribution of titanium dioxide in a formulation. Through the measurement of particle size, surface finish, and colour uniformity, producers are in a position to guarantee a consistent look, a good performance, and a pigment behaviour that is easy to predict for general production.
Common Testing Errors International Buyers Should Avoid in Titanium Dioxide Performance Testing
- Inadequate dispersion before testing.
- Inconsistent sample preparation.
- Ignoring environmental conditions.
- Using non-standard pigment ratios.
- Avoiding these issues ensures accurate titanium dioxide performance test results.
Avoiding these issues ensures accurate titanium dioxide performance test results.
