Industrial Coating: Types, Faults, and ASTM Standards
Industrial Coating is the application of a layer of material over a surface to protect it. Industrial coatings play a significant role in protecting materials from damage caused by environmental conditions, corrosion, and abrasion so that materials last for a long time and meet the test of time.
What is industrial coating?
Industrial coatings include applications applied on the steel and concrete surfaces in order to shield them from the natural environmental factors, corrosion, and abrasion. They commonly find their use for longer life of structures and equipment in the special sectors, such as the oil and gas industry, manufacturing, and construction.
Industrial Coating Types
Protective Coatings
It safeguards the surface from the corroding elements, chemicals and environment. Few examples in the epoxy and polyurethane.
Decorative Coatings
The appearance looks much attractive but provides little protection to surfaces. It is mainly used with consumer products and interior building applications.
Specialized Coatings
They have fire-resistance, heat-resistant and slip-resistance kinds of application.
Common Coating Faults
What Are Coating Faults?
Coating faults are the failure of the coating to carry out its intended function. This could be protection or enhancement of the surface. Such faults result from poor application, wrong materials, and environmental factors.
Examples of Coating Defects
Some of the common defects in coatings include:
- Adhesion failures
- Blistering
- Cracking
- Pinholes
- Sagging
- Chalking
Causes of Coating Malfunctions
Incorrect Surface Pre-treatment
Failure to clean or prepare the surface may result in some problems such as bad adhesion or blistering
Incorrect Coating Type
Failure to adopt the proper coating type for specific environmental and operational conditions results in some early time failure.
Environmental Variables
Degradation of this product over time, resulting from the influence of such conditions as humidity, extremely high or low temperatures and exposure to UV.
ASTM Specifications of Industrial Coating Flaws
ASTM specifications allow the definition of standards by which to identify and determine the rating of coating faults. Among the most common flaws identified in coatings are:
- Abrasion – ASTM D4060
- Adhesion failure – ASTM C1521
- Blistering – ASTM D714
- Chalking – ASTM D4214
- Cracking – ASTM G3694
- Delamination – ASTM D5824
- Rust spotting – ASTM D610
By following these standards, professionals can ensure better quality control and effective troubleshooting for coating-related issues.
Why are industrial coatings important?
Industrial coatings are used to protect surfaces, make them aesthetically pleasing and long-lasting. They prevent damage through corrosion, wear, and exposure to environmental factors, hence saving on maintenance costs while also lengthening the lives of critical infrastructure.
Conclusion
Industrial coatings play a very significant role in the maintenance and protection of structures and equipment in most industries. It is therefore essential to understand coating faults, causes, and ASTM standards so that the coatings do not fail with time. With this, the coated surfaces will definitely last long and become reliable.
