"Adhesive Sheet Technology" Seminar Held: Learning through Chemistry and Structural Design

This seminar explains adhesive technology based on chemistry and structural design from the perspectives of both manufacturers and users. It organizes evaluation criteria, test methods, and points to note for application and selection, supporting the enhancement of proposal and design capabilities.

While adhesive sheets (pressure-sensitive adhesive sheets) are increasingly used for waterproofing/anti-corrosion, temporary fixing, surface protection, and medical applications, the required performance varies widely depending on the application, making material selection and evaluation design difficult. Furthermore, a gap easily arises between the specifications and test results provided by manufacturers and the evaluation perspectives in the user's actual use environment, often making aligning expectations and building improvement cycles a challenge.

Course Details Adhesive sheets are utilized in various fields such as electrical/electronics, automotive, medical, architecture, civil engineering, and agriculture due to their high convenience and versatility. Especially in waterproofing/anti-corrosion, temporary fixing, surface protection, and medical applications, wide usage is progressing; however, it is important to understand the differences in functions and properties according to the application and to evaluate and select them appropriately. This course focuses on the core of "adhesive technology" and delves into evaluation methods and intentions from both manufacturer and user perspectives, centered on the fusion technology of chemistry and structural design.

Seminar Program Basic Composition and Processing of Adhesive Sheets, Supply Chain - Components of double-sided tape (double-separator, single-separator) / single-sided tape (adhesive, substrate, separator) - Adhesion mechanism (intermolecular force, anchoring effect), forms of adhesion (organic solvent type, emulsion type, solid type, hot melt type, monomer syrup type) - Differences from adhesives, basic processing, and supply chain basics

Composition, Types, and Characteristics of Adhesive Sheets - Substrate (material, thickness, performance) / Adhesive layer (rubber, acrylic, silicone, urethane, etc.) - Layer composition vs. cost/quality, selection examples (waterproof tape)

Evaluation Methods of Adhesive Sheets (Manufacturer's Perspective) - JIS Z0237 (2009) Testing methods of pressure-sensitive adhesive tapes and sheets - Peel test, shear force, tack, elongation/tensile strength, constant load holding power, etc.

Application Methods and Selection Considerations of Adhesive Sheets (User's Perspective) - Differences in perspective from manufacturer evaluations - Evaluations required in actual use (adhesive strength, optical spectrum, step/curved surface followability, waterproofness, repairability, high/low temperature/temperature cycle, long-term/weathering tests, etc.)

Introduction of Manufacturers and Their Specialty Technologies - Kawamura Sangyo Co., Ltd.: Coating (clean coating processing), plasma surface treatment, slitting processing, vacuum heat press processing, film sheet processing, etc. - DIC Corporation: Business domains, R&D strengths, waterproof tape joint development (#84 series PE foam), easy-dismantling solutions (DSA series) - Kyodo Giken Chemical Co., Ltd.: Waterproof tape joint development (300Z molecular gradient film), solvent-free high transparency Maklin Gel - Somar Corporation: Strengths as a manufacturer and trading company, re-peelable tapes (Somatac series), heat-resistant UV peelable / heat-resistant re-peelable / heat-resistant antistatic / heat-resistant permanent adhesive films, etc.

Summary, various double-sided/single-sided tapes (recent trends)

Target Audience Hardware/mechanical designers Young personnel in adhesive sheet development Engineers involved in product selection and evaluation (quality, production engineering, purchasing engineering, etc.) Practical personnel handling tapes/sheets for waterproofing/anti-corrosion, surface protection, and temporary fixing applications
