The Cerakote F-Series offers high-performance PFAS-free coatings known for their durability and resistance, ideal for various applications.
Cerakote is a well-known brand in the world of firearm coatings, industrial applications, and consumer products. Renowned for its durability, versatility, and aesthetic appeal, Cerakote has become a go-to choice for those seeking high-performance coatings. In recent years, the company has made significant strides in developing PFA-free coatings, which offer numerous benefits for both users and the environment. This article will explore what Cerakote is, the importance of PFAS-free coatings, and the various advantages they provide.
What is Cerakote?
Cerakote is a ceramic-based coating that can be applied to various surfaces, including metals, plastics, composites and wood. Originally developed for the firearms industry, Cerakote has expanded its applications to include automotive, aerospace, and consumer goods. The coating is known for its exceptional hardness, chemical resistance, and ability to withstand extreme temperatures.
Key features of Cerakote
- Durability: Cerakote coatings are designed to withstand harsh conditions, including abrasion, corrosion, and impact. This makes them ideal for applications where durability is paramount.
- Versatility: Cerakote can be applied to a wide range of materials, including aluminium, steel, polymer, and wood. This versatility allows for its use in various industries.
- Aesthetic appeal: Available in a high diversity of colours and finishes, Cerakote allows users to customise the appearance of their products. This is particularly popular in the firearms community, where aesthetics play a significant role.
- Heat resistance: Cerakote can withstand high temperatures up to 1,000°C without degrading, making it suitable for applications that involve heat exposure.
- Chemical resistance: The coating is resistant to a variety of chemicals, including oils, solvents, and cleaning agents, which is essential for maintaining the integrity of the coated surface.
The importance of PFAS-free coatings
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been widely used in various industries for their water- and grease-resistant properties. However, PFAs have come under scrutiny due to their potential health and environmental risks. These substances are persistent in the environment and can accumulate in the human body, leading to various health issues.
Recognising the growing concerns surrounding PFAS, Cerakote has developed PFA-free coatings that maintain the performance characteristics of traditional coatings while eliminating the associated risks.
Benefits of PFAS-free coatings
- Health and safety: By eliminating PFAS from their formulations, Cerakote reduces the potential health risks associated with exposure to these chemicals. This is particularly important for industries where workers may be exposed to coatings regularly.
- Environmental impact: PFAS-free coatings are more environmentally friendly, as they do not contribute to the pollution of water sources or soil. This aligns with the growing demand for sustainable practices in manufacturing and product development.
- Regulatory compliance: As regulations surrounding PFAS become stricter, using PFA-free coatings ensures compliance with current and future environmental laws. This can be a significant advantage for businesses looking to avoid potential legal issues.
- Performance: Cerakote’s PFAS-free coatings are designed to deliver the same high-performance results as their traditional counterparts. Users can expect the same level of durability, chemical resistance, and aesthetic appeal without the risks associated with PFAS.
Applications of Cerakote coatings
Cerakote coatings are used across various industries, each benefiting from the unique properties of the coating. Here are some notable applications:
Firearms
The firearms industry was the original market for Cerakote, and it remains one of the most significant applications. Gun owners appreciate the durability and customisation options that Cerakote provides. The coatings protect firearms in military and private hands from corrosion, wear, and environmental damage, ensuring they remain functional and visually
appealing.
Automotive
In the automotive sector, Cerakote is used to coat engine components, exhaust systems, and other parts exposed to high temperatures and harsh conditions. The coatings help improve performance by reducing friction and wear, while also enhancing the vehicle’s appearance.
Aerospace
Cerakote coatings are utilised in the aerospace industry for their lightweight and durable properties. They are applied to various components, including aircraft interiors and exteriors, to enhance performance and aesthetics while reducing weight.
Consumer products
From outdoor gear to kitchen appliances, Cerakote is increasingly used in consumer products. The coatings provide a protective layer that enhances durability and resistance to wear, making products last longer and look better.
Industrial applications
Cerakote coatings are also applied in industrial settings, where they protect machinery and equipment from corrosion and wear. This is particularly important in environments where equipment is exposed to harsh chemicals and conditions.
The application process
Applying Cerakote involves several critical steps to ensure a high-quality finish that maximises the coating’s performance and durability. Here’s a detailed overview of the process:
Surface preparation
The first and most crucial step in the Cerakote application process is surface preparation. Proper preparation ensures that the coating adheres effectively to the substrate. This step typically includes:
- Cleaning: The surface must be thoroughly cleaned to remove any dirt, oil, grease, or contaminants. This is often done using solvents or specialised cleaning agents.
- Sanding or abrading: For metals, sanding or abrasive blasting may be necessary to create a rough surface profile. This helps the coating bond better to the substrate.
- Degreasing: After sanding, the surface is usually degreased again to eliminate any residues that could interfere with adhesion.
- Masking: Areas that should not be coated are masked off using tape or other materials to ensure clean lines and prevent overspray.
Mixing the coating
Cerakote coatings come in a two-part system that includes a base and a hardener. Before application, the components must be mixed according to the manufacturer’s specifications. This step is crucial, as improper mixing can lead to poor adhesion and performance.
Application
Once the surface is prepared and the coating is mixed, the application can begin. Cerakote can be applied using various methods, including:
- Spray application: The most common method, where the mixed Cerakote is sprayed onto the surface using a spray gun with a nozzle size of 0.8-1.00mm. This allows for even coverage and control over the thickness of the coating.
- Dipping: In some cases, parts may be dipped into the coating solution, ensuring complete coverage. This method is less common but can be effective for certain shapes and sizes.
- Brushing: For small touch-ups or intricate areas, brushing may be used, although it is less common for large applications.
Curing
After application, the coated item has to flash off for 15 minutes and then be cured to achieve the desired hardness and durability.
Inspection and finishing
Once cured, the coated item undergoes a thorough inspection to ensure that the coating is uniform and free of defects. Any imperfections can be addressed at this stage. If necessary, additional touch-ups or a second coat may be applied.
