Cleaning tasks become easier! "What is the non-stick property of fluoropolymer coatings?"

The non-stick property makes it difficult for substances to adhere, making cleaning tasks easier. Here, we introduce the non-stick characteristics of fluoropolymer coatings.

■The "non-stick property" of fluoropolymer… Non-stick property refers to the characteristic of being easy to release and not adhere, or to adhere less, even to strongly adhesive substances. For example, fluoropolymers have excellent water and oil repellency, a large contact angle, and due to their molecular structure, they possess a property of being difficult to wet. The measure of wettability, "critical surface tension (γc)," is extremely low for fluoropolymers, making it easy for liquids to be repelled and difficult to wet. Coatings that utilize such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Reference data on non-stick properties】 ■Surface free energy of solids (dyn/cm) PTFE…18.5 PFA…17.8 FEP…17.8 ETFE…22.1 Fluoropolymers have low surface treatment free energy and possess properties that make them difficult to bond with various liquids and solids. By coating with fluoropolymer, dirt is less likely to stick and becomes easier to clean. *For detailed information on fluoropolymer coatings and non-stick properties, please download the PDF or contact us.

In 1968, we entered into a licensing agreement with DuPont in the United States. Among industrial fluoropolymer coatings, only manufacturers certified by Chemours (formerly DuPont) are permitted to process under the name "Teflon (TM) Coating." At Yoshida SKT, we provide coatings that maximize the properties of fluoropolymers tailored to our customers' needs. ■ We flexibly accommodate from one piece to mass production. ■ We can handle everything from small precision items to large tanks.
