Advantages to Teflon Coating

powder coating process

Protecting your product or equipment with protective powder coating is crucial for protecting your bottom line. Among the most popular methods of coating across multiple industries is Teflon coating. Teflon industrial coating can be incredibly versatile in defending your equipment and products from the elements, and offers plenty of benefits as a result.

1. Non-Stick Coating

Perhaps the biggest advantage of Teflon coating is its ability to turn almost any surface into a non-stick surface. For product manufacturers, this is likely very convenient for the needs of your consumer. Some products may even have customers specifically looking for products that have a non-stick Teflon coating.

 

This non-stick coating also makes it easier to operate your equipment. Depending on the material you work with, this can be incredibly important and a requirement when it comes to coating. 

2. Water and Heat Resistant

Teflon coating is incredibly resistant and easy to clean. Water does not cause the industrial coating to become saturated. If water does spill onto the surface, all that is typically required is a rag or washcloth to wipe it dry. 

 

Teflon is also resistant to high fluctuations in temperature. For example, it can withstand temperatures as high as 600 degrees Fahrenheit, making it one of the strongest types of coating materials against intense heat. As well as being cold resistant, this makes Teflon coatings ideal if you work in extreme conditions.

3. Chemical Resistant

If you work in any industry that may be dealing with hazardous chemicals, you know how much damage these chemicals can cause your equipment. For this reason, it is vital to apply a coating that helps protect your equipment from deterioration. Fortunately, Teflon coating is not affected by chemicals found in its environment. 

 

If you work with extreme chemicals, we can help ensure you get the coating that best suits your needs. Dealing with potential chemical reactions can be quite difficult. Teflon coating is a great choice if chemical resistance is at the top of your wish list. 

4. Electrical Properties

Similar to chemical reactions, potential electrical reactions can be dangerous and complicated. This is especially true if you are dealing with equipment that issues various frequencies. In this case, Teflon is one of the best coating materials for protection purposes. 

 

This is because Teflon has a low dissipation factor, but a high dielectric strength. This makes it incredibly versatile in allowing you to apply it to numerous surfaces that may come in contact with electrical charges. 

5. Low Friction

Now, a legitimate issue that often arises during industrial powder coating process lies in the material, and how that material responds to sliding across other surfaces. Some coating materials are rough and rugged, making the product it’s sprayed on next to impossible to move. Most Teflon coatings are very smooth and do not put up much resistance when moving or sliding against other materials. 

Think About Coating Services

Unfortunately, too many businesses completely overlook the importance of coating your products or equipment. Teflon operates seamlessly, requiring next to no maintenance after it has been applied. Your products and equipment will be protected while you don’t have to worry about continued maintenance. 

 

While it is possible for you to apply Teflon coating yourself, it’s recommended that you seek professional assistance to get the best outcome possible.

The PTFE Coating Process

PTFE Coating Services

Powder coating your products and equipment can be a paramount part of managing a business. Unfortunately, too many owners and managers overlook the importance of protective coating. Polytetrafluoroethylene, or PTFE coating, can help you save money on wear and tear.

What is PTFE?

Commonly referred to by brand names such as Teflon and Xylan, PTFE delivers some major benefits that make it one of the most sought-after coating choices across many industries. As a non-stick substance, PTFE coating can be versatile fit for almost any type of product or equipment. 

PTFE coating is chemical resistant, which is helpful when dealing with the complexity of chemical reactions with certain coating materials. It is also still effective at temperatures of up to 550 degrees Fahrenheit. While PTFE is heat resistant, it is also very resistant to cold temperatures; speaking to its versatility as a coating material. 

What is PTFE Used For?

In today’s world, you’re likely already using items with PTFE coating without even realizing it. Pots, pans, baking sheets, and other cookware is typically coated with PTFE coating. This is because of the non-stick properties PTFE provides. 

However, its non-stick properties are exactly why it’s popular with lawn furniture, automotive-related products, and industrial products. Other industries value its non-stick properties because it makes it easier to slide and move products around without a build-up of friction. 

Preparing Equipment For Coating

Before applying PTFE coating, we have to prepare the equipment to ensure the coating goes on properly. This is a very vital step of the process. Without proper preparation, the coating may not be applied properly, which will then diminish the benefits of PTFE coating. 

Every part and piece of the equipment needs to be blast-cleaned in order to prepare for the coating process. After blast cleaning, the surface is prepared. This is when the coating process begins. 

Spraying

This process can be rather easy and quick. In a simple spray system, the coating is fed into a spray gun, which then regulates the expulsion of the fluid into a smooth and steady stream. The liquid is forced into small droplets similar to how a can of spray paint operates. 

Small droplets help ensure an even coating and a smooth finish. This is the easiest and most efficient system when it comes to applying PTFE coating. Another benefit of the spray gun is that it can be used for awkwardly-shaped objects while requiring less specialist equipment. 

Post Coating

After PTFE coatings have been applied, the item is oven-baked and dried out.

If you are in need of PTFE coating in the Dallas, Texas area, our team here at Atlas Protective Coatings is here to help. We can ensure PTFE is applied properly and safely to your equipment or product. We want to be sure your equipment is protected. Give us a call today to find out how we can help you.

What is Powder Coating?

Powder Coating Pipes and Elbows

Powder coats are a type of protective coating that is applied as a free-flowing dry powder.

The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.

Powder coating is typically applied electrostatically and then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as “whiteware”, aluminium extrusions, and automobile and bicycle parts. Because of its method of application powder coated items have a more even tougher surface that covers all areas helping in repelling moisture and corrosion.

Powder Coating Steps

Powder Coating Steps for Metal

The powder coating process involves three basic steps:

  1. Part preparation or the pre-treatment
  2. The powder application
  3. Curing

Part preparation processes and equipment

Removal of oil, soil, lubrication greases, metal oxides, welding scales etc. is essential prior to the powder coating process. It can be done by a variety of chemical and mechanical methods. The selection of the method depends on the size and the material of the part to be powder coated, the type of soil to be removed and the performance requirement of the finished product.

Chemical pre-treatments involve the use of phosphates or chromates in submersion or spray application. These often occur in multiple stages and consist of degreasing, etching, de-smutting, various rinses and the final phosphating or chromating of the substrate. The pre-treatment process both cleans and improves bonding of the powder to the metal.

Another method of preparing the surface prior to coating is known as abrasive blasting or sandblasting and shot blasting. Blast media and blasting abrasives are used to provide surface texturing and preparation, etching, finishing, and degreasing for products made of wood, plastic, or glass. The most important properties to consider are chemical composition and density; particle shape and size; and impact resistance.

Silicon carbide grit blast media is brittle, sharp, and suitable for grinding metals and low-tensile strength, non-metallic materials. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing. Sand blast media uses high-purity crystals that have low-metal content. Glass bead blast media contains glass beads of various sizes.

Cast steel shot or steel grit is used to clean and prepare the surface before coating. Shot blasting recycles the media and is environmentally friendly. This method of preparation is highly efficient on steel parts such as I-beams, angles, pipes, tubes and large fabricated pieces.

Different powder coating applications can require alternative methods of preparation such as abrasive blasting prior to coating.

Powder application processes

The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a positive electric charge on the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the work piece by the powerful electrostatic charge. There are a wide variety of spray nozzles available for use in electrostatic coating. The type of nozzle used will depend on the shape of the work piece to be painted and the consistency of the paint. The object is then heated, and the powder melts into a uniform film, and is then cooled to form a hard coating. It is also common to heat the metal first and spray the powder onto the hot substrate. Preheating can help to achieve a more uniform finish.

Curing

When a thermoset powder is exposed to elevated temperature, it begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure. This cure process, called crosslinking, requires a certain temperature for a certain length of time in order to reach full cure and establish the full film properties for which the material was designed. Normally the powders cure at 200°C (390°F) for 10 minutes. The curing schedule could vary according to the manufacturer’s specifications.

The application of energy to the product to be cured can be accomplished by convection cure ovens or infrared cure ovens.

These are the three basic powder coating steps from start to finish. Contact us today for your powder coating & sandblasting needs.
