This guide uncovers facts on the importance of TiO2 in paints, its applications, key perks, considerations while choosing, and optimization essentials. Let&#;s dig in deeper!

Why Use TiO2 in Paint

Paint with Titanium Dioxide

Several reasons exist which make TiO2 an essential ingredient in paints. The key reasons are:

• It adds up whiteness and assists in neutralizing the colors of paints.
• The second thing it adds to paints is light scattering/bending. This is mainly because of the higher refractive index.
• Thirdly the masking power it gives to your paint is incredible. You can hide anything you want by applying the coating of paint containing TiO2.
• High brightness is another perk that you can get from Titanium dioxide. Apart from this, it also adds up to the overall paint strength.
• Resistance to acids is another aspect that clears the importance of TiO2 addition in paints.

Benefits of Titanium Dioxide in Paint

Addition of TiO2 results in a plethora of benefits, especially in paint products.

Find highlight on key perks right below:

TiO2 in Paint

&#; Environment friendly

The infrared light-reflecting property of TiO2 can help save energy. It keeps the interior of your house cooler by providing better insulation. Thus it reduces the need for air-conditioners. TiO2 is non-toxic, which means it contains no harmful elements that pollute the environment. Besides that, it can act as a photocatalyst to decompose environmental pollutants.

&#; Low Overall Cost

TiO2 plays its part in increasing the overall opacity of paints. It reduces the need for painting multiple coats, reducing the total cost and avoiding waste.

&#; Durability

TiO2 adds up hardness to the molecules of the paint. It is resistant to weathering and prevents paint degradation, thus making it last longer.

&#; Glossy Nature

TiO2 reflects infrared light to retain gloss and appear shiny. This property enhances the painted surface aesthetic and insulates the surface against heat. Thus making a particular vicinity more appealing and engaging.

&#; UV Resistance

TiO2 is stable against UV rays and prevents the degradation of paint. A greater refractive index is solely responsible for the better light bending phenomenon.

In other words, if UV light pertains for longer, it results in fading of the color with time. But TiO2 in paints prevents this from happening.

Best Titanium Dioxide for Paint

Titanium Dioxide Grades

Rutile-type TiO2 offers a higher level of bending or scattering. The rutile type has wide adoptability than the anatase type because of its greater refractive index value. This thing makes rutile type TiO2 desirable in paint products.

There is not a single rutile TiO2 grade that suits best when it comes to paints or coatings. This is why industries use two or more pigments to enhance multiple properties of color.

• For instance, the R-902 TiO2 adds to the paint&#;s resistance to chalks, higher glossiness, and masking power.
• The universally adopted grade of rutile TiO2 is R-706. The key features include high color uniformity, superb brightness, better gloss retention, and maximum durability. Most industries use it alone because of its universality.
• The third and last grade, which is popular, includes R-960. Things that add to the desirability have max. Tint retention, better dispersion, superb color retention, overbake resistance, and weathering resistance.

How to Optimize Titanium Dioxide Powder for Paint

The efficiency of each particle matters in paints. To get the most out of paint products, it is essential to optimize TiO2. Find insights on the process of doing it effectively:

&#; Optimization through Utilization of Dispersion Process

The term dispersion means separating the TiO2 particle in a way where there is some distance in between. The main reason is that when the particles are separated, they scatter light most effectively.

In natural existence form, the TiO2 particles have a strong bonding force between them. This requires sufficient work to isolate the particles from each other.

TiO2 Paint

Process Equipment

There are two main types of equipment that you can use to break the bonding forces between the TiO2 particles:

1. Disk disperser
2. Pearl miller

As the name reflects, the disk dispenser comprises a disk with edges or blades with upward and downward projections. They receive rotational power from a shaft connected to the motor. For optimization, you must place the solution containing the dispersant and TiO2 under the disk dispenser.

As you are familiar with, the TiO2 particles feature better bonding. This leads to flocculation. The term flocculation means grouping particles to form a cluster. To disperse them effectively, you need to use a dispersant.

With competitive price and timely delivery, Chuangge sincerely hope to be your supplier and partner.

The main function of the dispersant is to adsorb on the pigment surface and eliminate the flocculation or bonding phenomenon. A dispersant consists of several anchor groups that utilize long chains for better stabilization. In general, they have higher molecular weight. The anchor part settles on the surface of the pigment and chains projecting directly from the anchors.

1. Electrostatic Optimization

In electrostatic optimization, the electromagnetic forces induce the charges on the pigment particles. Negative charge underneath and a positive on the outer surface. This way, it eliminates the flocculation and results in better optimization. It is perfect for higher polarity systems.

Electrostatic Optimization

2. Steric Optimization

In steric optimization, the anchors and their chains are a barrier between the different pigment particles. These chains and anchors play a part in eliminating clusters or lumps.

Steric Optimization

The benefits of dispersion include

• Reduction in milling time
• Enhance viscosity
• Improve Coating characteristics

&#; Particles Distribution

It would help if you maximized the distance between the particles to achieve better scattering or bending efficiency. Here the filler materials serve you the best. Although they don&#;t add up to the bending or scattering efficiency, they can be useful for maintaining the distance between the pigment particles.

You can experience crowding in this situation. Also, when the particle size is identical to the TiO2 particles, the distance between them refers to even spacing.

How to Choose Paint Pigment Titanium Dioxide

Choosing the right paint pigment requires you to pay attention to multiple aspects.

You can quickly check these three selection criteria in the technical documentation from the pigment producer.

&#; Structure of Crystals

Try to select the pigment with the right crystal structure, having the desired light scattering power. When it comes to light bending or preventing their penetration into an object rutile type performs better. A greater refractive index makes this happen.

&#; Size of Particle

Accurate or correct particle sizing in paint leads you to experience better performance and results. This will help you achieve better scattering.

Scattering Efficiency of TiO2 particles

&#; Final Treatment

The application to which you will subject the end product determines the composition/amount that a final inorganic treatment takes. This, in the end, have a great impact on the overall photoactivity. When employing TiO2 paint for exterior coatings, choose silica, alumina, and zirconia. This is true, especially for rutile grade TiO2.

Uses of Paints with Titanium Dioxide

The applicability of the paints having TiO2 is vast. Get insights on key notable applications:

• TiO2 features wide adaptability, especially when it comes to automobile paintings.
• You can coat the exteriors as well as interiors of concrete buildings with these paints
• You can use titanium dioxide paints to coat window frames.
• TiO2-containing paints can be used for solar panels and wind turbines.
