4/14 Webinar: Water and Oil Repellent Treatment Achievable with Fluoride-Free Solutions

A detailed explanation of the concept of surface design that controls sliding angle and contact angle hysteresis, along with an approach to enhance water and oil repellency without using fluorine, from both theoretical and practical perspectives.

■Title: "Fluorine-Free Water and Oil Repellent Treatment Technology Achievable - Guidelines and Examples for Surface Design to Improve Wetting Fundamentals and Liquid Sliding Properties" As PFAS regulations accelerate, surface designs that achieve water and oil repellency without fluorine are gaining attention. This seminar will systematically explain the fundamentals of wetting, dynamic wettability evaluation, design guidelines for improving sliding properties, and the latest examples of fluorine-free surface treatments by leading researchers. ■Date and Time: April 14, 2026 (Tuesday) 13:30 - 16:30 ■Target Audience for the Seminar - Individuals engaged in surface treatment and modification work - Those involved in research and development related to imparting water and oil repellency, stain resistance, and anti-adhesion properties to various substrate surfaces - Individuals engaged in research and development of fluorine (PFAS) alternative technologies and fluorine-free surface treatment and modification technologies ■Knowledge Gained from the Seminar - Fundamental knowledge/theory related to wettability - Correct knowledge of wettability evaluation techniques (static/dynamic contact angle, contact angle hysteresis, sliding/falling angle) - Know-how for creating surfaces/interfaces with excellent water and oil repellency, stain resistance, and anti-adhesion properties without fluorine
