This article systematically introduces the concept, features, functions, applications, selection methods, and common problem solutions of ATM powder coating, with a focus on the functions of ATM powder coating, to help readers better understand what ATM powder coating is, as well as its features and applications.
What Is ATM Powder Coating?
ATM powder coating refers to a high-performance powder coating specifically applied to the surface of ATM (Automated Teller Machine) cabinets. It belongs to a category of products used for information technology equipment in the field of industrial coating.It is a solvent-free dry solid powder that is evenly deposited on the surface of metal cabinets through electrostatic spraying. After high-temperature baking, the powder melts and levels out, eventually curing to form a dense and tough protective coating.
Features of ATM Powder Coating
The main features of ATM powder coating are as follows.1. Excellent Decorative and Functional Properties
It can provide ATMs with a wide range of colors, gloss levels (high gloss, matte, etc.), and special texture effects, such as wrinkle and metallic effects.
2. Excellent Physical and Chemical Protection
It forms a dense and tough coating with high hardness, excellent impact resistance, wear resistance, and scratch resistance, effectively protecting against daily physical impacts and scratches. At the same time, it also provides excellent resistance to chemical corrosion and can protect sensitive internal electronic components from electrostatic interference.
3. Environmental Friendliness and Cost-Effectiveness
Since the coating itself contains no solvents or volatile toxic substances, there are no “three wastes” emissions during production and use. It is environmentally friendly and complies with environmental regulations. At the same time, its high utilization rate and low maintenance costs also provide good economic benefits.
Functions of ATM Powder Coating
The main functions of ATM powder coating are specifically reflected in the following aspects.1. Basic Protective Function
As the “physical armor” of an ATM, it provides protection against corrosion, impact, wear, and UV aging by forming a dense coating, ensuring that the cabinet remains structurally intact and internal electronic equipment operates safely under outdoor weather conditions, high-temperature exposure, and daily impacts.
2. Functional Expansion
It can provide ATMs with special functions according to their application environment. For example, anti-static coatings protect sensitive components, while anti-graffiti and fingerprint-resistant coatings facilitate cleaning and maintenance. Some special formulations can also provide thermal insulation to adapt to extreme climates.
3. Commercial Aesthetic Function
Through a wide range of colors, gloss levels, and texture effects, such as metallic finishes and wrinkle textures, it helps banks establish a consistent brand image. At the same time, good gloss and color retention ensure that the equipment maintains a like-new appearance after years of use, enhancing user confidence.
Applications of ATM Powder Coating
What types of kitchenware use powder coating? The specific application areas are as follows.ATMs and Financial Terminals
This is the most direct application. Powder coating is used on the entire metal cabinet and exterior components of ATMs. Its function is not only to provide a wide range of colors and textures to create a brand image, but more importantly, to form a strong protective layer that resists scratches, corrosion, and outdoor aging.
Other Self-Service Terminals
Equipment with application scenarios similar to ATMs, such as self-service check-in/check-out terminals at airports and railway stations, vending machines, and electronic information kiosks, also uses powder coating. Taking vending machines as an example, powder coating can provide excellent weather resistance and UV resistance, while its surface is easy to clean and disinfect, which is particularly important for equipment used to sell food and beverages.
Similar IT Equipment
From a technical classification perspective, the same types of powder coatings are also used on metal products such as computer cases, laptop housings, server cabinets, and safes that require good protection and appearance.
How to Choose ATM Powder Coating
When choosing ATM powder coating, we may face the problem of not knowing how to make the right selection. Based on our industry experience, we recommend focusing on the following aspects when selecting ATM powder coating.
Key selection points are outlined below.
1. Consider the Application Environment and Choose the Right Resin System
This is fundamental to determining the service life of the coating. Powder coatings based on different resin systems vary significantly in weather resistance and corrosion resistance.
(1) Outdoor ATMs (bank branches and street locations): Weather-resistant resin systems must be used. Particular attention should be paid to polyester resin powder coatings or fluorocarbon powder coatings. They can effectively resist ultraviolet (UV) radiation and prevent coating chalking and fading, which is essential for extending the service life of the equipment. Some high-performance outdoor powder coatings can have an expected service life of 15 to 25 years or even longer.
(2) Indoor ATMs (shopping malls and office building lobbies): Epoxy resin powder coatings or epoxy-polyester hybrid powder coatings can be selected. These coatings have strong adhesion, high hardness, excellent corrosion resistance, and relatively economical costs, making them sufficient for the protection requirements of indoor environments.
2. Consider Performance Requirements and Select Additional Functions
In addition to basic corrosion resistance and weather resistance, ATMs may face certain special challenges that require powder coatings with specific functions:
(1) Anti-Graffiti/Fingerprint Resistance: For machines located in high-traffic areas, powder coatings with anti-graffiti or fingerprint-resistant properties can be selected to facilitate daily cleaning and maintain a clean appearance.
(2) Anti-Static: ATMs contain precision electronic components. Selecting anti-static powder coatings can effectively prevent static electricity accumulation and avoid interference with or damage to electronic equipment.
(3) Touch and Appearance: Some high-end equipment may require a special soft touch or fine texture effect, for which corresponding types of powder coatings are available.
3. Consider the Appearance Design and Match the Brand Image
Powder coatings offer a wide range of options in terms of color and texture.
(1) Color and Gloss: From high gloss to matte, and from standard colors to customized colors, powder coatings can meet various requirements and match the visual identity standards of banks.
(2) Special Effects: If a more distinctive appearance is required, special texture powder coatings such as metallic effects, wrinkle textures, and hammer textures can also be selected to enhance the texture and recognition of the equipment.
4. Other Key Considerations
(1) Supplier and Quality: Choose a powder coating manufacturer with extensive experience to ensure stable product quality and batch-to-batch consistency.
(2) Process Compatibility: Ensure that the selected powder coating is well matched with the existing spraying and curing processes, including temperature and time.
Common Problems and Solutions for ATM Powder Coating
The most common problems encountered during the use of ATM powder coating are mainly reflected in the following aspects. Based on our industry experience, we have proposed corresponding solutions to help effectively resolve powder coating problems you may encounter.1. Coating Appearance Defects
These are usually caused by contamination on the substrate surface, such as oil stains, or by moisture absorption of the powder.
Solution: Focus on strengthening the degreasing process during pretreatment and ensure that the compressed air is dry and oil-free. At the same time, check whether the powder has absorbed moisture and adjust the curing temperature curve when necessary.
2. Poor Adhesion and Coating Peeling
Poor quality of the phosphating or passivation film on the substrate, or insufficient curing temperature, are common causes.
Solution: Strictly check the concentration of pretreatment chemicals, regularly conduct cross-cut adhesion tests, and adjust the curing oven temperature and time according to the powder's Tg value.
3. Weather Resistance Failure
If an indoor epoxy resin powder coating is mistakenly used on an outdoor ATM, prolonged exposure to sunlight can easily cause aging.
Solution: Outdoor cabinets must use highly weather-resistant polyester resin or fluorocarbon powder coatings, and the lightfastness grade of the pigments should be controlled.
4. Uneven Powder Application Caused by Electrostatic Shielding
Powder is difficult to deposit in cabinet corners or deep grooves due to electric field shielding.
Solution: Adjust the spray gun voltage and powder output, use the “multiple thin spraying” method, or use a special powder with stronger charging properties.
5. Insufficient Mechanical Properties of the Coating
Excessive curing of the coating can increase brittleness, or the substrate may experience excessive deformation stress.
Solution: Control the temperature difference in the curing oven within ±5°C, avoid over-baking, and reinforce sheet metal components that are prone to deformation.
