◆Yoshida SKT Co., Ltd.◆ 【Currently Available for Free】 Take the first step in preparing for PFAS regulations. We are providing a sample kit to experience non-fluorinated coatings.
― Compare release properties and lubricity on the spot. For a limited time, we are also offering a free PFAS countermeasure guide for the manufacturing industry. ― Currently, discussions are underway in Europe regarding the strengthening of regulations on PFAS (perfluoroalkyl and polyfluoroalkyl substances), and there is a growing likelihood that fluoropolymer resins will become subject to regulation. In response to this trend, Yoshida SKT has started offering a free "PFAS-Free Coating Experience Sample Kit" to support manufacturers considering a switch to PFAS-free materials. This kit is designed to allow users to physically compare non-fluorinated coatings, and it has been well received as a first step in gathering information and evaluating products in preparation for regulatory compliance. ― Experience and compare six types of non-fluorinated coatings ― The experience kit includes six types of non-fluorinated coatings, such as silicone-based, graphite-based, and ceramic-based, along with a fluoropolymer coating for comparison. Using sample plates affixed to an A4-sized backing and dedicated adhesive tape, users can test the differences in release properties and lubricity on the spot.

◆Yoshida SKT Co., Ltd.◆ What are the differences between PTFE, PFOS, and PFOA? Free PFAS guide for the manufacturing industry.
Fluororesins, widely used in manufacturing sites, possess excellent properties such as low friction and non-stick characteristics, but they are classified as a type of "PFAS (per- and polyfluoroalkyl substances)." Currently, only certain PFAS substances that raise concerns about their impact on the environment and health are regulated in Japan, while in the EU, discussions are underway to expand the scope of regulation. Therefore, companies need to keep track of overseas regulatory trends and alternative technologies to continuously assess their impact on their products. In light of this background, Yoshida SKT is offering a free document titled "PFAS Countermeasures Guide for the Manufacturing Industry," which summarizes the latest trends and alternative technologies as of January 2025. This guidebook clearly explains the definition of PFAS, the regulatory situation both domestically and internationally, and provides comparative tables detailing the structures, properties, and toxicity differences of representative substances such as PTFE, PFOS, and PFOA. Additionally, it specifically introduces alternative coating technologies that do not use PFAS. For more details, please check the product page.

◆Yoshida SKT Co., Ltd.◆ Understand the differences between PTFE, PFOS, and PFOA! Release of the PFAS Countermeasure Guide for the Manufacturing Industry
Fluororesins, widely used in manufacturing sites, possess excellent properties such as low friction and non-stick characteristics, and are classified as a type of "PFAS (per- and polyfluoroalkyl substances)." In Japan, only certain PFAS that raise concerns about environmental and health impacts are regulated. Among PFAS, PTFE (fluororesin) differs in nature from PFOS, PFOA, and PFHxS, which are regulated under international treaties (the POPs Convention), and it is considered non-harmful except for significant high-temperature use. However, a broad PFAS regulation proposal that includes PTFE is being considered within the EU, and if adopted, it could lead to strengthened international regulations. If regulations on fluororesins become a reality, the impact on the manufacturing industry would be immense, as there are no complete alternative technologies available, making compliance extremely challenging. In light of this background, Yoshida SKT is offering a free guide titled "PFAS Countermeasures for the Manufacturing Industry," which summarizes the latest trends and alternative technologies. This guide clearly explains the definition of PFAS, the regulatory situation, and compares the properties of PTFE, PFOS, and PFOA in a table format, while also introducing alternative coating technologies that do not use PFAS.

About吉田SKT
Towards the "optimal solution" for surface treatment - optimizing adhesion prevention, lubricity, and corrosion resistance to enhance productivity.
To maximize the performance of manufacturing equipment and machine parts, Yoshida SKT derives the "optimal solution" tailored to our customers from hundreds of surface treatment technologies. - Decreased productivity due to adhesive troubles - Instability in product quality due to friction - Early deterioration of equipment due to corrosion We respond to these challenges in the manufacturing field with our extensive track record and reliable technical expertise. In 1963, we began fluoropolymer processing. In 1968, we signed a licensing agreement with DuPont (now Chemours), supporting manufacturing innovations for over 2,000 customers across various industries, from automotive to medical and aerospace. Furthermore, in 2024, we are focusing on the development of next-generation products, such as PFAS-free coatings, contributing to the advancement of sustainable manufacturing. With a three-base system in Nagoya, Tokyo, and Yamaguchi, we flexibly respond to both mass production and custom orders. Our consistent quality management system ensures that we deliver reliable quality. For solving challenges in the manufacturing field, trust the surface treatment experts at Yoshida SKT.
