May 12 (Tue) AndTech WEB Online Zoom Seminar: "Fundamentals and Applications of Adhesive Sheet Development and Evaluation Methods from Both Manufacturer and User Perspectives"

AndTech Co., Ltd. (Headquarters: Kawasaki, Kanagawa; President: Masao Suyama; hereinafter "AndTech"), as part of its R&D development support Zoom seminars, will hold a "Adhesive Sheet" seminar featuring a leading expert to meet the growing need for problem-solving using adhesive sheets.

Focusing on the fusion technology of "structure" and "materials," this seminar will delve deeply into adhesive technology. It will explain the bonding technology of adhesives from both perspectives: imparting know-how (NEEDS) on how to effectively use adhesive tapes in products, and development/design (SEEDS) that meets customer requirements.

This seminar is scheduled for May 12, 2026.

Full Program Details (Please see below if you are interested in the details) ────────────────────────────────────────────── [Lecture Abstract] Adhesive sheets are indispensable in a wide variety of fields, including electrical/electronic, automotive, medical, construction, civil engineering, and agriculture, due to their convenience and versatility. They are widely used, particularly for waterproofing, corrosion prevention, temporary fixing, surface protection, and medical applications, but the functions and properties required vary greatly depending on the application. In this seminar, we will focus on the core of "adhesive technology," emphasizing the fusion technology of chemistry and structural design. We will delve into evaluation methods and their intent from both the manufacturer and user perspectives. Furthermore, you will gain a comprehensive understanding of adhesive sheets through the following content.

[Program] 1. Basic Composition, Processing, and Supply Chain of Adhesive Sheets 1-1 Basic Composition ① Double-sided tape (double separator, single separator) ② Components of single-sided tape (adhesive, substrate, separator) 1-2 Adhesive Mechanism ① Concept of adhesive strength - Intermolecular forces - Anchoring effect (physical engagement) ② Forms, types, and characteristics of adhesion - Organic solvent-based - Emulsion-based - Solid-based - Hot-melt-based - Monomer syrup-based ③ Differences from adhesives, strength consideration factors 1-3 Basic processing and supply chain fundamentals ① Types of basic processing ② Supply chain fundamentals 2. Composition, Types, and Characteristics of Adhesive Sheets 2-1 Base/Substrate: The central layer that largely determines tape characteristics - Materials - Thickness - Performance 2-2 Adhesive Layer: The "face" of the tape changes depending on material selection - Rubber materials - Acrylic materials - Silicone materials - Urethane materials, etc. 2-3 Layer composition: A factor that significantly affects cost and quality in tape development 2-4 Selection examples for waterproof tape 3. Evaluation Methods for Adhesive Sheets (Manufacturer Perspective) 3-1 JIS Z0237 (2009) Testing methods for pressure-sensitive adhesive tapes and sheets 3-2 Main testing methods ① Adhesive strength/peel test ② Shear strength ③ Tack test ④ Elongation/tensile test ⑤ Holding power under constant load ⑥ Others 4. Adhesive Sheet Application Methods and Points to Note During Selection (User Perspective) 4-1 Differences in perspective from manufacturer evaluation 4-2 Required evaluations ① Adhesive strength ② Optical spectrum ③ Step/curved surface followability ④ Waterproofing ⑤ Repairability ⑥ Others (high temperature, low temperature, temperature cycle, long-term, weather test) 5. Manufacturer Introductions and Their Specialized Technologies 5-1 Kawamura Sangyo Co., Ltd. ① Coating (clean coating processing) ② Plasma surface treatment ③ Slitting processing ④ Vacuum heat press processing ⑤ Film sheet processing, etc. 5-2 DIC Corporation ① Business areas ② R&D strengths ③ Joint development of waterproof tape #84 series PE foam ④ Easy-dismantling solution DSA series ⑤ Various double-sided/single-sided tapes (recent trends) 5-3 Kyodo Giken Chemical Co., Ltd. ① Joint development of waterproof tape 300Z molecular gradient film ② Solvent-free high-transparency Make-rin Gel 5-4 Somar Corporation ① Strengths as both a manufacturer and a trading company ② Various re-peelable tapes (Somatac) ③ Heat-resistant UV-peelable adhesive film ④ Heat-resistant re-peelable adhesive film ⑤ Heat-resistant antistatic adhesive film ⑥ Heat-resistant permanent adhesive film ⑦ Others: Somatac WA (low tack), Somatac UV (UV peel), Somatac CR (cooling peel), Somatac TE (heat peel) ⑧ Dicing tape, internal process materials 6. Summary
