Fluororesin Coating: "What is the Water and Oil Repellency of Fluororesin?"

What are the typical characteristics of Teflon fluoropolymer coating, specifically "water repellency and oil repellency"? Let me introduce the mechanism.

■What is the "Water Repellency" of Fluororesin? "Water/Oil Repellency" refers to the property of a material's surface to repel water and oil. A well-known example that illustrates this property is the lotus leaf. The lotus leaf utilizes this water repellency to keep itself clean and less prone to wetting, allowing for smooth photosynthesis. Teflon fluororesin also possesses this "water/oil repellency." For instance, even if a liquid tends to spread on a material, applying a Teflon fluororesin coating to the surface can impart water/oil repellency, causing the liquid to bead up and reducing its tendency to spread. You can find detailed information in the PDF document below. ---------------------------------------- 1. What is water/oil repellency? 2.

Teflon Coating: "What is the difference between frying pan use and industrial use?"

I will explain the difference between Teflon coating commonly seen on frying pans and the Teflon coating processed for industrial use.

◆Differences Between Frying Pans and Industrial Teflon Coatings◆ Teflon processing for frying pans typically involves products made with PTFE at a thickness of about 20 to 50 micrometers. PTFE is a representative fluororesin and is the first resin developed. Formally, "Teflon" is a registered trademark of the fluororesin by DuPont in the United States, while the general term is fluororesin processing (coating). PTFE not only excels in non-stick and water-repellent properties but also has good heat resistance, making it suitable for frying pans. On the other hand, industrial Teflon coatings not only have the non-stick properties like frying pans but are also used for various applications such as improving slip, protecting substrates from chemicals, and enhancing insulation properties. Therefore, the types of resins used include not only PTFE but also PFA and FEP. Our company can process PTFE coatings, but we also offer Teflon coatings using various materials and technologies. *Note: "Teflon" is currently a trademark of Chemours. Our company has a licensing agreement with Chemours and is capable of processing Teflon coatings in our own factory.

Fluororesin coating "Measures against film peeling and foreign matter contamination"

A composite coating that excels in "release properties and sliding properties" of fluororesin and "hardness and wear resistance" of inorganic materials. Measures against foreign substances for fluororesin coatings.

When applying coatings to molds and various packaging machines, there are applications where complaints arise due to film peeling and foreign matter contamination. For example, molds subjected to strong pressure, chutes and guides that are constantly in contact with products, and "heat sealers" where metal parts touch each other are some of these cases. ■ Hardness Comparison 【Fluororesin Coating】 - Pencil Hardness: F to H (PTFE) 【Bicoat】 - HV 700-900 (NNYK-01) "Bicoat" is a coating system that achieves the ideal functions of "release properties and sliding properties" combined with "high hardness and wear resistance" by integrating surface treatment technologies for inorganic and organic materials. 【Features of Bicoat】 ◆ Not only does it provide reliable release and sliding properties, but it also has high hardness and excellent dimensional accuracy. ◆ It is suitable for coating areas where micron-level dimensional accuracy is required. *For more details, please refer to the PDF document or feel free to contact us.

Fluororesin coating "Low friction properties of PTFE coating"

We will introduce the low friction properties of PTFE coating within fluoropolymer coatings.

■Features of PTFE Coating PTFE has the characteristic of having extremely low resistance due to friction compared to other resins. By processing PTFE coating, the static friction coefficient of the substrate surface can be reduced, allowing two objects in contact to be moved with a small force. ■Low Friction of PTFE Coating - Due to the strong atomic bonds within PTFE molecules, the intermolecular forces of the contacting material with PTFE molecules are reduced. - Friction (sliding) causes PTFE molecules to adhere slightly to the contacting material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with few irregularities. - The orientation of PTFE molecules makes it easier to alleviate friction resistance. It is believed that the molecular structure influences the low friction coefficient of PTFE coating. *For more details on fluoropolymer coatings, including PTFE coatings, please download the catalog or contact us.*

Fluororesin Coating: "What are Heat Resistance and Cold Resistance?"

The representative characteristics of fluororesin coating, specifically Teflon coating, are "heat resistance and cold resistance." This will be explained in detail.

■Reasons why fluoropolymer (PTFE) excels in heat and cold resistance The molecular structure of PTFE consists of carbon-carbon (C-C) bonds surrounded completely by fluorine atoms (F). The breaking of C-C bonds or C-F bonds at high temperatures is one aspect of "PTFE degradation." The C-C bonds are less likely to break because they are protected by the fluorine atoms (F). The bond strength of C-F bonds within PTFE molecules is significantly greater than that of bonds between other atoms. Additionally, the high bond energy of C-F bonds is another reason for its excellent heat and cold resistance. ■Applications utilizing the heat and cold resistance of fluoropolymers In the case of fluoropolymer coatings, for example, baking molds utilize the non-stick properties provided by the coating to prevent baked goods from sticking to the mold. Furthermore, since it also possesses heat resistance, it can be safely used in applications such as baking in an oven. Additionally, in household irons, the heat plate is coated with fluoropolymer to take advantage of its smoothness and heat-resistant properties.

Fluororesin coating that can minimize warping of thin plates.

Yoshida SKT's developed product "10UNDER" is a groundbreaking fluororesin coating that minimizes substrate deformation and enables processing at a film thickness of 10μm.

■What is the Thin Film Fluoropolymer Coating "10under"? Fluoropolymer coatings may be requested in a thin film form when dimensional stability of the substrate is a priority. In the case of standard fluoropolymer coatings, a thickness of at least 20-50μm has been required to maintain appearance and performance. Yoshida SKT has worked on development to meet these requests and has announced the "Thin Film Fluoropolymer Coating '10under'." ■Features of 10under - Non-stick properties equivalent to standard fluoropolymer coatings - Capable of thin film processing of approximately 10μm, reducing dimensional changes - Suppresses transparency despite being a thin film *For more details, please download the materials or contact us.*

Teflon Coating "Method of Visual Inspection"

To use Teflon coating for a long time, not only selection and processing technology are important, but also quality inspection. Let me introduce Yoshida SKT's quality inspection.

This is an introduction to one of the inspection processes for Teflon coating, the visual inspection. 【Three Points of Visual Inspection】 ■ Coating Processing Range We visually confirm whether the coating film after processing is in accordance with the discussed matters and your order by referring to the drawings and individual specifications. We mainly check the processing range of the coating and, if there are any masking specifications, we confirm the designated areas and ranges. ■ Confirmation of Specified Coating Materials We verify whether the processing specifications are in accordance with the discussed matters and the order form. This mainly involves checking the color tone of the coating and processing records. ■ Confirmation of Coating Film Quality We check the quality of the coating film. The method primarily involves visual inspection and touch. Depending on the size of any abnormalities, tools such as magnifying glasses are used to ensure that there are no defects in the coating film (such as cracks, foreign matter adhesion, blisters, peeling, or damage) across the entire surface of the film. *For more details on visual inspection, please visit our website via the link or contact us.*
