Published Date: 08th Mar 2022

With benefits like efficiently cleaning surfaces and providing numerous benefits to materials, surface treatment chemicals are gaining rapid momentum across multiple industries worldwide for diverse applications. Of all their perks, corrosion resistance, smoother finish, and longer life are the most prominent advantages boosting their adoption. In fact, it is also expected that the Global Surface Treatment Chemicals Market would witness around 5.7% CAGR during 2021-26. Looking for more reasons behind the accelerating demand for surface treatment chemicals worldwide? Stick through the end and explore more.

Prominent Applications of Surface Treatment Chemicals

The demand for surface treatment chemicals is escalating dramatically across different industries, where some of the largest consumers of these chemicals are listed below. Have a look:

  • Automotive Industry

The demand for surface treatment chemicals across the automotive industry is principally to add a layer of protection on the vehicles and provide them resistance from rust & wear. Additionally, this layer of chemicals would also enhance their durability while pretreating the surface ready for the finished layer. 

  • Aerospace Industry

The use of surface treatment chemicals across the aerospace industry is principally to improve the finish of components that are made with additive manufacturing. Here, the surface treatment chemicals remove prior layers to attain the final condition required.

  • Coil Industry

Across the coil industry, surface treatment chemicals are used for removing oil & grease that might form on the coil. In the treatment, the chemicals are either acidic or alkaline-based cleaners that depend upon the nature of contamination or substrate on the coil.

  • Metalworking Industry

The demand for surface treatment chemicals in the metalworking industry is principally for purposes like decoration, reflectivity, better hardness, and prevention of corrosion. Moreover, these chemicals are also popularly known for extending the durability of the metal and witness extensive application in cleaning stainless steel.

  • Wood Industry

To enhance the durability of wooden products and avoid problems like degradation, fungal rot, decay, & termite, the demand for surface treatment chemicals is escalating dramatically across the wood industry.

The Escalating Demand for Surface Treatment Chemicals

Undoubtedly, the utilization of surface treatment chemicals is rising substantially across different industries, and it brings up the question, why? So, the following are some key aspects attributing to the rapidly mounting demand for surface treatment chemicals:

  • Swift expansion of different industries like automotive, aerospace, metal, glass, & wood industry, among others across regions like North America, South America, Europe, Middle East & Africa, and Asia-Pacific
  • Growing awareness about the benefits like protection against corrosion & damages caused by the changing environmental effects of using surface treatment chemicals on materials
  • Active participation of leading manufacturers in developing & producing eco-friendly treatment chemicals & reducing the generation of industrial wastes & hazardous substances
  • Rapidly increasing number of building & construction projects to habitat the exponentially rising population augmenting the demand for surface treatment chemicals

Types of Surface Treatment Chemicals

Surface treatment chemicals provide a protective layer to a material against corrosion, rust, wear, & other environmental damages. They are also used on different materials as a pretreatment to achieve their smooth finishing. Let's look at numerous types of surface treatment chemicals used in diverse applications:

  • Corrosion Protection Chemicals are compounds that decreaseslow down, or prevent the possibility of corrosion in materials like metal or alloy when they come in contact with liquid or gas.
  • Cleaners are amongst the most extensively utilized surface treatment chemicals. These chemicals are used principally to enhance the appearance of the surface, clean off tough stains like oil & grease from industrial equipment or machinery, and disinfect or sterilize laboratory equipment, among others. 
  • Anodizing Chemicals transform the metal surface into a decorative, corrosion-resistant, durable, & wear-resistant oxide layer. These chemicals are used majorly in decorative furniture & sculptures.
  • Passivation Agents in surface treatment are utilized on providing a layer of acid solutions on stainless steels to remove contaminants & form a passive film on the surface. 

Some Popular Ways of Surface Treatment

Surface Treatment Chemicals are utilized extensively in multiple applications across various industries. Some of these treatment methods are listed below. Have a look.

  • Electroplating

The Electroplating surface treatment process is known to form a thin metallic coating on the material and passes the positively charged electrical current through a solution containing dissolved metal ions & negatively charged electrical current through the metallic part. This surface treatment is performed on metals like copper, nickel, gold, silver, zinc, & tin, among others. 

  • Electro Plating

This treatment process is pretty similar to that of the above-cited treatment, yet the only difference resides with the unavailability of electricity. Here, in place of electricity, the treatment uses a reduction agent containing the plating solution. 

  • Chemical Treatment

In this surface treatment process, the chemical builds thin films of sulfide & oxide through chemical reaction and are typically used for corrosion protection, metal coloring, and surface priming for materials that would be painted. Among all, black oxide is the most common surface treatment used m=on steel and for passivation to remove iron from stainless steel. 

  • Thermal Spraying

It is a type of surface treatment that involves melting or heating materials that are accelerated and then mechanically collided & bonded to the surface. This Thermal Spraying chemical surface treatment is usually practiced on larger structural objects for protection against high temperatures by providing a thermal barrier coating for heat management.

  • Hot Dipping

The Hot dipping surface treatment is a process where the material is part dipped in dissolved til, zinc, aluminum, among others. These materials are hot-dipped principally to have corrosion resistance in the rapidly changing weather conditions.

Wrapping Up

These were just a few of many aspects attributing to the burgeoning adoption of surface treatment chemicals across different industrial verticals worldwide. Based on these factors, the Global Surface Treatment Chemicals Market is projected to create several growth opportunities for the leading players and encourage them to develop new & easier ways of treatments with advanced chemicals & solutions through 2026.
