This article is an attempt to let you know about the use of titanium dioxide (TiO2) in paints, coating. A metal of great strength, titanium. A combination of its strength, heat resistance, water and salt resistance, and lightweight makes it an ideal metal for a number of applications. When it comes to pure titanium it can be considered strong and corrosive while gaining greater flexibility and malleability when mixed with another metal.
There are six grades of pure titanium (grades 1,2,3,4,7 and 11) and 4 varieties of titanium alloys. In addition to titanium, titanium alloys generally contain aluminium, molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper.

Why is Titanium Dioxide Used In The Paint Industry?
Titanium dioxide (TiO2) is widely used in the coatings industry as a white pigment. Because it effectively scatters visible light, both whiteness and brightness are imparted to a coating when it is incorporated.
Anatase and rutile are the two crystal structures of titanium dioxide available for commercial use. The main reasons for preferring Rutile TiO2 pigments over anatase pigments are that these pigments scatter light more effectively, are more stable and have a longer shelf life.
The main reason to choose Titanium Dioxide in the Paint industry
We all know that exposure to sunlight can dull the color of clothes, outdoor paints and whatnot. TiO2’s refractive properties, durability and brilliance of color is the main reason to be used in outdoors plastic as it gives them a rigid strength to avoid any kind of weathering and light damage due to its refractive property. When entering or leaving a material, the amount of change in the path of light depends on the refractive index, which is determined by the electronic structure of the molecules.
Top uses of Titanium Dioxide used in industries
- Amorphous SiO2: durability
- Engineered SiO2 / Al2O3 for optimal spacing
- Amorphous Al2O3: durability
- Crystalline Al2O3: dispersibility
- Organic: flow & wetting
TiO2 Impact on Paint Weather Resistance
It can be tricky to study the weather resistance of a coating. An outdoor exposure test over a period of several years is the most effective way to determine the weather resistance of a coating system. It is necessary, however, to evaluate the weather resistance of a paint system in much shorter time frames during the development process.
Three main factors of degradation of outer coating are
- Effect of direct UV light.
- Photocatalytic degradation
- Temperature
Titanium dioxide helps in creating an opaque film over the outer surface which would lead to dispersion of light. This makes the outer surface last longer.
How Do You Mix Titanium Dioxide With Paint?
Titanium dioxide is a white substance generally in a fine powdered form that is insoluble in water. An acidic environment is the most common means of using hydrogen peroxide. Solubilizing titanium oxide in water is performed by hydrogen peroxide.
Titanium Dioxide Percentage in Paint?
In large quantities, titanium dioxide negatively affects both the hiding power and the adhesion of paint. If the PVC content is above 30% in TiO2, the white color strength will increase.
To ensure that a system containing titanium dioxide pigment is able to provide whiteness and hiding power due to scattering, particle-free PVC must not exceed a threshold value of 30% by volume. As long as PVC in TiO2 is below 30%, the total PVC, taking all solid particles into account, of a system can be (much) higher than 30%.
FAQ –
Is titanium dioxide used in paint?
Yes, Titanium dioxide can be used in paints, coatings, plastics.
What is the importance of titanium dioxide?
As well as being odourless, titanium dioxide is absorbent. When powdered, this pigment serves as an opacifier and a source of whiteness.
Is titanium dioxide safe in paint?
Yes, in most of the paint or titanium dioxide is found.
How long does titanium dioxide coating last?
Between 5 to 10 years.
