Investigation of UV-Curable Pressure-Sensitive Adhesives

Investigation of UV-Curable Pressure-Sensitive Adhesives

Pressure-sensitive adhesives, often referred to as PSAs, are a special type of adhesive that bonds to surfaces simply by applying light pressure—no solvents, heat, or other external aids are required. They are characterized by their ease of adhesion and effortless removal, and their adhesive layer remains flexible and does not harden over extended periods. PSAs are primarily used as raw materials for manufacturing pressure-sensitive tapes, producing a wide range of PSA products such as tapes, stickers, films, and sheets.

A Brief Discussion on UV-Curing Inks

A Brief Discussion on UV-Curing Inks

UV-curable ink is an ink that undergoes a cross-linking reaction when exposed to ultraviolet (UV) light with a wavelength ranging from 200 to 450 nm. Under the irradiation of UV light, this ink can instantly transform from a liquid state into a solid state; hence, it is also referred to as UV ink. Its main components include prepolymers, monomers, organic pigments, photoinitiators, and additives. UV ink boasts several advantages, such as rapid drying speed, high production efficiency, low curing energy consumption, excellent gloss, superior resistance, no solvent volatilization, and environmental friendliness. As a result, it is increasingly widely adopted in the printing industry and has become a new direction for ink development.

Exploring the Application of Light-Curing in Vacuum Plating

Exploring the Application of Light-Curing in Vacuum Plating

Vacuum plating involves placing the object to be coated into a vacuum chamber and then heating it to a specific temperature, causing the metal or non-metallic material to enter an evaporated state. The evaporated material flies around in the vacuum environment and adheres to the surface of the object being coated. After cooling, a thin film is formed. This deposition process relies on the high-speed movement and collision of particles; therefore, the film deposition rate and film quality in vacuum plating depend on factors such as vacuum quality, material purity, temperature, the distance between the material and the substrate, and the duration of the deposition process.

Introduction to Local UV Coating Technology

Introduction to Local UV Coating Technology

Localized UV coating is an innovative surface finishing technique for printed materials, offering a new option for enhancing print quality. This localized UV coating technology is based on the principle of UV curing. A UV varnish is applied or printed onto the surface of a finished printed material, selectively coating specific areas of the printed design to create a glossy, textured effect with a raised appearance. As a result, certain areas of the printed material exhibit enhanced brightness, transparency, and abrasion resistance. While highlighting key elements of the design, this technique also significantly enhances the decorative appeal of the printed surface.
