1. Overview

Tapes, adhesives, and applicators are critical components in modern manufacturing and assembly processes. These materials enable permanent or temporary bonding between surfaces through mechanical adhesion, chemical bonding, or physical interlocking. Adhesives include liquid glues, pressure-sensitive tapes, and structural adhesives, while applicators encompass dispensing systems, spray equipment, and automated bonding machines. Their importance spans industries such as automotive, electronics, construction, and healthcare, offering advantages in weight reduction, vibration damping, and design flexibility.

2. Main Types and Functional Classification

3. Structure and Composition

Adhesive tapes typically consist of a carrier material (PET, foam, or fabric) coated with adhesive layers (acrylic, rubber, or silicone). Liquid adhesives contain polymers (epoxy, polyurethane), solvents or water carriers, and additives for specific properties. Applicators integrate precision dispensing valves, heated hoses, or robotic arms for controlled application. Pressure-sensitive adhesives require optimized viscoelastic properties to balance adhesion and cohesion forces.
