Lösungsmittelgebundene

Lösungsmittelgebundene refers to a class of materials or products that utilize solvents as a binding agent. In this context, a solvent is a liquid that has the ability to dissolve, suspend, or extract other materials, usually without chemically altering either the solvent or the solute. When a solvent is used as a binding agent, it serves to hold together the solid components of a formulation. As the solvent evaporates or is otherwise removed, it leaves behind the solid constituents in a cohesive form, creating a film, coating, adhesive layer, or solid mass.

This principle is widely applied across various industries. In the paint and coatings industry, solvent-borne paints use solvents to carry pigments and resins. Once applied, the solvent evaporates, leaving a solid paint film on the surface. Similarly, adhesives often rely on solvents to dissolve the adhesive polymers, allowing them to spread easily and wet the surfaces to be bonded. Upon solvent evaporation, the polymers solidify and create a strong bond.

Other applications include inks, where solvents help to dissolve dyes or pigments and control viscosity, and in certain pharmaceutical preparations, where solvents are used to dissolve active ingredients before they are solidified into tablets or capsules. The choice of solvent is critical and depends on factors such as the solubility of the components, desired drying time, safety considerations, and environmental regulations. The term "lösungsmittelgebundene" directly translates to "solvent-bound" and emphasizes the role of the solvent in the material's application and final state.
