Toll coating is when a specialized coating company applies a thin material layer to a customer-supplied substrate. Typically, the coating is applied to improve the substrate’s performance. It is also known as contract or custom coating, providing access to diverse coating capabilities without investments in equipment, facilities, or personnel.

Most contract coating companies often have expertise in coating technologies and access to cutting-edge equipment, allowing them to provide high-quality and consistent services. They may offer surface preparation, drying, curing, quality control, and packaging services. This article will highlight this popular coating technique’s unique applications and advantages.

Industries That Benefit From Toll Coating

Contract coating services offer a range of advantages to various industries, allowing them to enhance their products’ performance, durability, and aesthetics. It finds applications in diverse sectors, from packaging to electronics, automotive to medical devices. The following industries commonly benefit from these services:


Toll coating enables the application of special coatings onto automotive parts such as engine components, chassis, brake systems, and other metal surfaces. It protects against corrosion, wear, and environmental factors, ensuring the longevity and reliability of automotive parts. It can also offer noise reduction properties, reducing vibrations and minimizing unwanted sounds within the vehicle cabin.


Depending on the specific needs of the electronic applications, the applied coatings can provide enhanced insulation, dielectric properties, or optical qualities. This is especially useful in industries where efficacy and dependability are the highest priority, such as telecommunications and consumer electronics. In addition, the technique can contribute to the miniaturization of devices by applying thin and uniform coatings.

Medical and Healthcare

Custom coating services enable the application of biocompatible coatings on medical devices, such as catheters, surgical instruments, and diagnostic equipment. They ensure compatibility with human tissues, reducing the risk of adverse reactions and improving patient safety during medical procedures. In addition to biocompatibility, they also allow for incorporating antimicrobial coatings.


The process becomes crucial in meeting the growing demand for inventive packaging solutions by enhancing materials’ functionality and visual appeal. It enables the application of protective coatings, barrier films, and adhesives onto diverse packaging substrates. Consequently, these coatings enhance the material’s durability, moisture resistance, and printability.

Printing and Publishing

Various coatings can contribute to producing specialty printed materials, such as security labels or packaging with anti-counterfeiting features. They can also be applied with unique characteristics, including holographic effects or invisible inks, to prevent unauthorized reproduction and protect brands and products.

Unique Advantages of Toll Coating Services

Toll coating services offer several unique advantages that make them valuable for industries and businesses. Some of these benefits include:


Opting for contract coating services can be cost-effective for businesses, especially those with intermittent or variable needs. Companies can outsource their requirements to specialized service providers instead of investing in coating equipment, maintenance, and training.

Customization and Flexibility

Coating parameters — such as thickness, composition, functionality, and appearance — can be tailored to specific needs. Toll coaters can also handle projects of varying scales, accommodating both small-batch productions and large-scale manufacturing.

Quality Control and Consistency

Coating companies implement stringent quality control measures throughout the process. They have established testing, inspection, and monitoring protocols to ensure consistent and reliable coating results. This helps businesses maintain high product quality and meet industry standards.

Specialized Expertise

Service providers have specialized knowledge, expertise, and experience in coating trends. They also keep abreast of the most recent developments and can provide valuable guidance and insights to their consumers.

Time Efficiency

Toll coaters have dedicated teams and streamlined processes, enabling faster turnaround times compared to in-house setups. This allows businesses to meet tight deadlines, accelerate product development cycles, and respond swiftly to market demands.
