Proposal for Coating Selection: "Coating Performance Measurement Service" *Materials Available

Proposal for Coating Selection: "Coating Performance Measurement Service" *Materials Available

To meet the need of wanting to confirm the effectiveness before coating, Yoshida SKT measures the coating surface with its unique know-how.

"I want to test the effectiveness of coatings using materials produced in-house in advance." "I am considering introducing coatings but am struggling with how to select them." To address these concerns, we propose measuring coating performance using our unique know-how, allowing for a comparative review before introducing coatings. Please feel free to consult us about preparing sample pieces. - Do you have any of these issues? During resin molding, resin sticks to molds or extruders, causing problems. After researching, I found that surface treatment is an effective measure to prevent sticking, but there are various types of resins and additives depending on the product, and I don't know which surface treatment to choose. - With our coating performance measurement service, you can use the materials you are currently using to check the adhesion with the coating, facilitating smooth real machine testing. ■ Measurement of Release Force of Melted Resin Pellets We measure the release force between melted resin pellets and the coated surface, allowing you to confirm the degree of peeling from the coating numerically. *For applications and to download materials, please visit the official Yoshida SKT website below.

What are the differences between fluoropolymer coatings: PTFE, PFA, and FEP?

What are the differences between fluoropolymer coatings: PTFE, PFA, and FEP?

We will introduce the differences between fluoropolymer PTFE, PFA, and FEP.

Differences in Types and Characteristics of Representative Resins for Teflon Coating and Fluororesin Coating ■ Resin Name PTFE (Polytetrafluoroethylene) ■ Characteristics It has the highest continuous use temperature of 260°C, and in addition to heat resistance, it excels in non-stick and low friction properties. ■ Alternative Name Tetrafluoroethylene, 4F ■ Resin Name PFA (Perfluoroalkoxyalkane Polymer) ■ Characteristics An improved resin of PTFE, it has the same continuous use temperature of 260°C as PTFE. It has a low thermal melt viscosity, allowing for a continuous coating with fewer pinholes that could not be achieved with PTFE, making it the best-performing fluororesin for corrosion-resistant coatings. Additionally, PFA is superior in non-stick properties compared to PTFE for certain applications, making it suitable for high-temperature release coatings. ■ Resin Name FEP (Perfluoroethylene Propylene Copolymer) ■ Characteristics An improved resin of PTFE, but with lower heat resistance than PTFE. It can achieve a smooth coating with fewer pinholes through firing. ■ Alternative Name 4F6F, Tetra-hexafluoride

[Case Study of Blade Surface Treatment] Thin Film Coating: Swiftly Resolving Blade Adhesion Issues

[Case Study of Blade Surface Treatment] Thin Film Coating: Swiftly Resolving Blade Adhesion Issues

We propose a release coating that does not compromise the sharpness of cutting tools! We are currently offering a collection of case studies on solving adhesive problems with coatings.

We would like to introduce a case where the adhesion of adhesive from packaging film to cutter blades was prevented. ■Concern In a certain packaging process, during actual production, packaging film with adhesive would stick to the cutter blades, causing cutting issues and misalignment, which frequently led to line stoppages. As a result, we were unable to achieve the production quantities calculated from the takt time. ■Effect of Coating We adopted our product "MRS-003." This allowed us to keep the processing temperature below 250°C, eliminating concerns about blade blunting. Additionally, due to the thin film of just 1 micron, the sharpness of the blade edge was maintained. 【Key Points】 ■Purpose of Surface Treatment: Quality and operational stability, speed enhancement, compliance with safety and environmental requirements ■Required Functions: Non-stick and release properties, long lifespan ■Adopted Treatment: MRS-003 *We are currently offering examples of improvements in adhesive troubles with cutting tools and processes. For more details, please visit the official Yoshida SKT website or feel free to contact us.

[Case Study] Freed from the application work of release agents with convex release coating.

[Case Study] Freed from the application work of release agents with convex release coating.

We achieved cost and time savings through a coating that provides long-lasting prevention of sticking.

The manufacturing process of weather strips involved transporting extruded rubber on rolls while heating and drying it in a furnace. Due to changes in the rubber material formulation for environmental measures and durability, it became necessary to process the rubber at higher temperatures than before, resulting in the rubber becoming sticky immediately after entering the furnace. When a common fluororesin coating was applied to the transport rolls, it was confirmed that the rubber stuck to them like a suction cup. By adopting our "Super TP Coating," we significantly reduced the sticking of the rubber and achieved a relatively soft contact surface. [Case Study] ■ Purpose of surface treatment: Quality improvement, operational stability, reduction of work loss, compliance with safety and environmental requirements ■ Required functions: Non-stick, release properties, long lifespan ■ Treatment adopted: Super TP Coating *For more details, please refer to the PDF document or feel free to contact us.

For those unsure about choosing surface treatment: Release and non-stick coatings *Materials available

For those unsure about choosing surface treatment: Release and non-stick coatings *Materials available

Release properties are necessary. I want to reduce adhesion. I want to save on cleaning effort. It effectively meets all your requests! We introduce a surface treatment that excels in release and non-stick properties.

"Non-stick" refers to a property that makes it easy to release from strongly adhesive materials, meaning it either does not adhere or adheres with difficulty. Utilizing non-stick properties, we introduce surface treatments (coatings) that are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. [Surface treatments chosen for non-stick and release purposes (partial list)] ■ Non-stick, lubricity, heat and cold resistance, chemical resistance, water and oil repellency, electrical properties 'Teflon (TM) fluoropolymer coating' ■ Release properties, high hardness, dimensional stability, lubricity, wear resistance 'Bicoat (R)' ■ Prevention of adhesion of highly adhesive materials 'Adhesive release coating series' 'MRS coating' (silicone-based coating) ■ Release of molten resin at high temperatures 'FSR coating' *For more details, please click to download the PDF or feel free to contact us.

Teflon coating "Quality inspection by licensed processing manufacturers"

Teflon coating "Quality inspection by licensed processing manufacturers"

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

Here, we introduce part of the quality inspection for Teflon coating. ■ Product Inspection We verify whether the product meets the meeting notes and order specifications based on the meeting minutes, drawings, and individual items. ■ Coating Appearance Inspection The processed coating is visually observed under diffuse daylight (equivalent). In principle, any detection of blisters, cracks, peeling (including interlayer peeling), substrate exposure, or transparency will result in a failure. ■ Film Thickness Measurement Inspection Film thickness refers to the thickness of the processed coating measured using a thickness gauge adjusted based on the substrate board and a standard board placed on top. ■ Pin Hole Inspection Pinholes are a general term for tiny defects that can potentially be detected electrically. However, it typically refers to one type of tiny defect, specifically holes that resemble those made by a needle, found in the remnants of bubbles. *Inspection items may vary depending on the coating specifications. Please contact us for more details.

[Surface Treatment Solution Case] Release of UV-curable resin with a 1μm thin film surface treatment!

[Surface Treatment Solution Case] Release of UV-curable resin with a 1μm thin film surface treatment!

Achieving adhesion prevention for UV-curable resin used in display panel sealing! Ultra-thin film surface treatment 'Nano Process(R)'

■Concerns In the process of manufacturing display panels for TVs and other devices, sealing is done using UV-curable resin. However, the adhesive resin tends to stick to the jigs, leading to an increased likelihood of product defects. ■Requests The standard Teflon™ anti-adhesion coating results in a film thickness of several tens of micrometers, which causes fine irregularities to be transferred to the resin, raising concerns about the impact on products requiring precision. Additionally, the 400°C heat treatment during coating can cause warping of the jigs, and the UV light necessary for curing the sealing resin can compromise the adhesion of the coating, making it unusable. ■Solution Coating NanoProcess® TLS-200 ■Problem Resolution - Significant reduction in product defects due to prevention of resin adhesion - Improved precision leading to longer lifespan of jigs - Increased production efficiency *For details on the effects and background of the solution, please download the PDF or contact us.*
