Paint Additives: Their Different Types & Importance in the Industrial Sector

One of today's most significant challenges for paints is their resistance to external influences and, at the same time, deliver durability. They have to meet the highest standards and aesthetics & designs. For these reasons, paint additives are gaining immense popularity as an intelligent solution to create a formulation with excellent properties. A recent research report has cited 3.5% compounded annual growth rate (CAGR) for the paint additives market in the GCC region during 2021-26.


Paint additives have their application in numerous sectors like building & construction, industrial, & automobile. In the industrial sector, the usage of paints varies as per the requirements since every paint formula is unique and differs by the additives present in it. Additives alter the paint properties to enhance the quality of the finished product. Let's look at a few properties that additives improve in paints:
Various Ways Additives Enhance the Paint Characteristics in Industrial Applications

1.    Abrasion Resistance: Scratches are the marks on the surface that occur due to the movement of sharp objects. The resistance to scratches refers to as abrasion resistance. The higher the abrasion resistance level, the more the ability to withstand damages. Therefore, it is one of the most crucial properties of paint additives and plays a vital role in protecting the surface from any damage.

2.    Leveling: Leveling is another prominent property of paint additives. An innumerable defect, such as orange peeling, craters, fisheyes, crawling, pinholes, etc., can occur during paint application. The local surface tension differences of raw materials form the defects and hold them while drying. A flat smooth surface gives a better appearance & improved performance. In addition, proper leveling help make end-users take sound decisions.

3.    Gloss: Gloss is the result of improved leveling. The proper leveling of paint helps improve the glossiness of the surface, which helps characterize the surface’s roughness. The lesser the roughness, the higher the glossiness. The gloss of the surface makes a huge impact on the appearance of the surface.

Additives have the ability to modify paint properties and behavior and are crucial for better formulation and eliminating the defects that occur during paint application. Hence, choosing the most appropriate additives for the particular application of paint is most crucial. Let’s have a look at the different types of additives available in the market:

Different Types of Paint Additives

1.    Rheology Modifiers: Rheology modifiers play a crucial role in achieving optimum rheological characteristics. They help control the viscosity of paints while they are being manufactured, applied, or dried. Moreover, they are also beneficial for enhancing the shelf life of paints.

2.    Anti-Foamers: Anti-foamers help eliminate the formation of foams during paint application. However, anti-foamers can also cause defects like cratering, popping, fisheyes, etc. Hence, these additives should be used in small quantities.

3.    Wetting and Dispersing agents: Wetting & dispersion agents are beneficial for the homogeneous distribution of solid particles in the liquid. A prominent example of such agents in paints is the even distribution of color particles in the formulation to ensure perfect coloration color.

 


Final Words
There are numerous additives to alter the paint properties for industrial use. Some additives might interfere with others. Therefore, its manufacturer's task is to balance effectively the formulation to achieve the most optimal properties as per the requirement. In addition, it is important to do research regarding what additives are mixed in the paints and how will they affect the finished surface before buying. A painting expert can help in determining the appropriate paint best suited to consumer needs.
