POWDER COATING

Commercial grade powder coating is a highly durable and efficient finishing process used in various industries to protect and enhance the appearance of metal surfaces. It involves applying a fine, dry powder composed of pigments, resins, and other additives electrostatically onto a metal substrate. The powder adheres to the surface due to the electrostatic charge and forms a uniform and consistent coating.

WHAT ARE THE BENEFITS OF POWDER COATING?

Benefits of commercial grade powder coating over conventional painting processes include:

Durability: Powder coating offers exceptional durability and resistance to scratches, chipping, fading, and corrosion. The cured coating forms a tough barrier that protects the underlying metal surface.
Environmentally Friendly: Powder coating is an environmentally friendly alternative to liquid paint. It contains no volatile organic compounds (VOCs) or solvents, reducing air pollution and health risks.
Cost-Effective: Powder coating is a cost-effective solution due to its high material utilisation rates. Overspray can be collected and reused, minimising waste and reducing overall costs.
Versatility: Powder coating provides a wide range of colour options, textures, and finishes. It can be customised to achieve different appearances, such as glossy, matte, or textured finishes.
Efficiency: The electrostatic application of powder coating ensures efficient material usage, as it allows for precise and uniform coverage. It also eliminates the need for primers or additional layers commonly required in traditional painting processes.

WHAT IS THE PROCESS OF POWDER COATING?

The process of commercial grade powder coating typically consists of the following steps:

Surface Preparation: The metal surface is cleaned and prepared to remove any dirt, oil, rust, or other contaminants that could hinder proper adhesion of the powder coating.
Application: The powder coating material is sprayed onto the metal surface using specialised equipment. The powder particles are charged with an electrostatic charge as they are sprayed, which causes them to adhere to the grounded metal surface uniformly.
Curing: The coated metal is then subjected to high temperatures in a curing oven. The baking time and temperature may vary depending on the specific powder coating material and the requirements of the job. Typically, the curing process takes around 10 to 30 minutes at temperatures ranging from 150 to 230 degrees Celsius.

During the curing process, the powder coating melts and chemically reacts to form a tough, protective film. The heat also allows the powder coating to flow and level out, resulting in a smooth and even finish. As the coated metal cools, the powder coating hardens, providing excellent adhesion and durability.

Powder Coating gives consumers, businesses, and industries one of the most economical, longest lasting, and most colour durable quality finishes available on virtually any type of metal. With a wide range of powder coating colours available. Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes. Colours stay bright and vibrant longer. Powder Coating Industries provides a quality in house powder coating service for our clients.

SANDBLASTING

Commercial sandblasting is a highly effective surface preparation technique used in various industries to remove contaminants, rust, old coatings, and other imperfections from metal surfaces. It involves the use of compressed air and abrasive media, such as sand, grit, or shot, to propel particles at high velocity onto the surface, resulting in thorough cleaning and preparation.

WHAT ARE THE BENEFITS OF SAND BLASTING?

Benefits of commercial sandblasting include:

Effective Surface Preparation: Sandblasting efficiently removes old coatings, rust, scale, and other contaminants from metal surfaces, providing a clean and receptive surface for subsequent treatments, such as painting or powder coating.
Versatility: Sandblasting can be applied to various metal surfaces, including steel, aluminum, cast iron, and more. It is suitable for different shapes, sizes, and complex structures, making it a versatile method for surface preparation.
Enhanced Adhesion: By removing existing coatings and contaminants, sandblasting promotes optimal adhesion of subsequent coatings, ensuring better durability and longevity.
Time and Cost Savings: Sandblasting is a time-efficient process compared to manual methods of surface preparation. It can rapidly remove coatings and surface imperfections, reducing labor costs and project turnaround time.
Eco-Friendly: Sandblasting is an environmentally friendly method as it does not involve the use of harsh chemicals or solvents. Proper containment and waste disposal measures can be implemented to minimise environmental impact.

WHAT IS THE PROCESS OF SAND BLASTING?

The process of commercial sandblasting typically consists of the following steps:

Surface Preparation: The metal surface is thoroughly cleaned to remove any loose debris or contaminants. This step ensures that the sandblasting process can effectively remove the target material without interference.
Abrasive Propulsion: The chosen abrasive media, such as sand or grit, is mixed with compressed air and propelled through a specialised blasting nozzle. The high-pressure stream of abrasive particles strikes the surface, removing unwanted coatings, rust, or other surface imperfections.
Containment and Safety Measures: To ensure safety and minimise environmental impact, sandblasting is typically conducted within an enclosed space or a designated blast booth. Proper ventilation systems and personal protective equipment (PPE) are employed to protect operators from dust inhalation and to contain the abrasive media.
Surface Inspection: Once the sandblasting process is complete, the surface is inspected to ensure that all contaminants and coatings have been effectively removed. Any remaining debris or imperfections are addressed before proceeding to the next steps of the surface treatment process.

The duration of commercial sandblasting can vary depending on factors such as the size and condition of the surface being treated, the type of abrasive media used, and the desired level of cleaning or preparation. Typically, the process can take anywhere from a few minutes to several hours, depending on the complexity of the project.

We can sandblast products up to 6m in length. For delicate smaller parts we fine blast prior to powder coating for better adhesivity.

ACID STRIPPING

Commercial acid stripping, also known as acid etching or chemical stripping, is a surface treatment method commonly used in industries to remove paint, coatings, rust, and other contaminants from metal surfaces. It involves the application of acid-based solutions to chemically dissolve and strip away the unwanted layers.

WHAT ARE THE BENEFITS OF ACID STRIPPING?

Benefits of commercial acid stripping include:

Effective Coating Removal: Acid stripping efficiently removes various types of paint, coatings, and contaminants from metal surfaces, including rust, epoxy coatings, powder coatings, and more.
Versatility: Acid stripping can be used on different metal surfaces and substrates, making it a versatile method for surface preparation and restoration.
Precision: Acid stripping allows for precise control over the stripping process. The dwell time and acid concentration can be adjusted to achieve the desired level of removal without damaging the underlying metal substrate.
Time and Cost Savings: Acid stripping is a time-efficient method compared to manual or mechanical methods of coating removal. It can rapidly dissolve and strip away coatings, reducing labor costs and project turnaround time.
Surface Restoration: Acid stripping can reveal the original surface condition of the metal, allowing for further inspection, repairs, and subsequent treatments like painting or powder coating.
Compatibility: Acid stripping can be used on various metal alloys and substrates, including steel, aluminium, brass, and copper, among others.

It's worth mentioning that while acid stripping can be effective, it requires careful handling and expertise to ensure safety and optimal results. Proper containment, waste disposal, and adherence to safety guidelines are crucial when performing commercial acid stripping.

WHAT IS THE PROCESS OF ACID STRIPPING?

The process of commercial acid stripping typically consists of the following steps:

Surface Preparation: Before acid stripping, the metal surface is thoroughly cleaned to remove loose debris, oils, and other contaminants. This step ensures that the acid can effectively penetrate the target material and provide optimal stripping results.
Acid Application: The acid-based solution is carefully applied to the surface using brushes, sprayers, or immersion methods. The specific type of acid used depends on the type of coating or contaminant being removed. Commonly used acids include hydrochloric acid (muriatic acid), sulfuric acid, or proprietary acid-based solutions.
Dwell Time: The acid is allowed to dwell on the surface for a specific period to facilitate the chemical reaction and penetration. The dwell time can vary depending on the type and thickness of the coating or contaminant, as well as the ambient conditions.
Neutralisation: After the dwell time, the surface is thoroughly rinsed with water or a neutralising agent to halt the acid's chemical activity. This step is crucial to prevent further reaction and ensure the removal of any residual acid from the surface.
Surface Inspection: Once the acid stripping process is complete, the surface is inspected to verify the removal of the targeted coatings or contaminants. Any remaining residues are addressed before proceeding to subsequent surface treatments.

It's important to note that commercial acid stripping should be performed with caution and in compliance with safety guidelines. Adequate ventilation, personal protective equipment (PPE), and proper waste disposal practices are essential to ensure the safety of operators and minimise environmental impact.
