Acrylic resins used in adhesives differ from those used in coatings in the following ways: Performance Characteristics Acrylic resins used in adhesives High bond strength: They must form a strong bond between different materials and cure quickly to generate sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives cure in seconds, achieving fast bonding. Good flexibility: W...

If you are a manufacturer of—or a user of—hot-melt adhesives, you are well aware that while most hot-melt pressure-sensitive adhesives (HMPSAs) appear virtually identical in appearance, the specific manufacturing processes employed during their blending result in distinct sets of advantages and disadvantages. Hot-melt pressure-sensitive adhesives are complex mixtures composed of SBC (Styrene-Butad...

1. Hot Melt Adhesives – Coating Methods Hot melt adhesives are 100% solids, require heating to melt, and solidify upon cooling. They are solvent‑free and cure quickly, making them ideal for high‑speed production. Roll Coating How it works: Molten adhesive is transferred to the substrate via a heated gravure or applicator roll. Coating thickness is controlled by the roll’s surface pattern. Applicat...

Varnish is one of the “unsung heroes” of the printing process. Many people think it is only used to make paper look glossier, but it actually serves many other purposes. Simply put, applying varnish to a printed product is like giving it a functional outer layer. It protects the printed image while helping the product withstand friction, moisture, stains, and further processing. First, the Most Pr...
