PTFE coating
The non-stick coatings from FMT, based on fluoroplastics such as PTFE, FEP, and PFA, are designed to prevent unwanted adhesion. They can be used in various contexts. Whether you want to reduce or even eliminate the use of release agents through an anti-adhesive surface, optimize the cleaning effort of your components, or significantly improve wear resistance, a customized non-stick coating from FMT can help you.
The main properties of PTFE coatings
The temperature resistance of PTFE coating is 260°C in continuous use and 290°C for short periods. The coating has an excellent non-stick effect and hydrophobicity, as well as very good chemical resistance. The coefficient of friction is very low due to the formula and can even be as low as 0.02. The abrasion resistance is good and can be very good depending on the addition of additives. The coating can be dielectric or antistatic depending on the formula. In addition, the stability is maintained at very low temperatures.
How PTFE coatings are applied
PTFE is available in two basic forms, namely as powder and as liquid, and each has different application methods. Smaller objects can be immersed and then rotated to remove excess material.
The final option is to negatively charge the PTFE particles with an electrode-equipped spray gun and create an electrostatic coating. The last step after any of these applications is to cure the PTFE-coated object at 400 °C.
PTFE coating service
PTFE coatings have many excellent properties and advantages. PTFE stands for polytetrafluoroethylene, a material that is known for its high chemical resistance and heat resistance. Here are some of the key properties and advantages of PTFE coatings:
-
Non-stick properties: PTFE coatings are extremely slippery and have excellent non-stick properties. This makes them ideal for applications where adhesion or sticking of materials should be avoided.
-
Corrosion resistance: PTFE coatings are highly resistant to chemical and corrosive influences. This allows them to be used in a variety of environments without being damaged or losing their properties.
-
Temperature resistance: PTFE coatings are extremely temperature-resistant and can withstand temperatures of up to 260°C. This allows them to be used in applications that are exposed to high temperatures without being damaged.
-
Abrasion resistance: PTFE coatings are highly resistant to abrasion and can withstand scratches, wear and other mechanical influences. This means they remain in good condition even after prolonged use.
-
Electric Insulation: PTFE coatings are very good electrical insulators. This makes them suitable for applications where electrical insulation is required.
A PTFE coating can make a significant difference in many applications
A PTFE coating can make a significant difference in many applications. It offers excellent non-stick properties, corrosion resistance, temperature resistance, abrasion resistance, and electrical insulation. In the industry, PTFE is commonly used in areas such as food production, medical technology, chemical industry, and automotive industry to reduce wear, simplify cleaning, increase the durability of components, and minimize the risk of contamination or short circuits. PTFE coatings can also be used in the kitchen to reduce food sticking to pans and other cookware and to facilitate cleaning.
