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...

In the coatings industry, pure acrylic emulsion and acrylic emulsion (typically meaning styrene-acrylic) are two common waterborne binders. Their main differences lie in composition, performance, and application. 1. Composition Pure acrylic emulsion: Made from 100% acrylic monomers (e.g., butyl acrylate, methyl methacrylate). Acrylic emulsion (styrene-acrylic): Copolymer of styrene and acrylic mon...
