Dispersion binder

Dispersion binders are liquid or paste-like binders that are distributed (dispersed) in the form of fine particles in an aqueous or non-aqueous phase. They play a central role in many industrial applications, especially in the production of paints, varnishes, adhesives and building materials. The fine particles usually consist of polymers produced by emulsion polymerization or other processes and are used to bind different components of a system together.

A characteristic feature of dispersion binders is their stability, which is ensured by the use of stabilizers or surfactants so that the particles in the dispersion do not re-aggregate into larger units. When the end product dries or hardens, the binder particles cross-link or coagulate and form a homogeneous, solid layer that ensures adhesion, flexibility and mechanical stability.

Dispersion binders offer many advantages, including easy processing, low emissions and the ability to manufacture environmentally friendly products. They are also versatile and can be optimized by adapting the polymer structure to specific requirements, such as weather resistance, chemical resistance or elasticity. They are widely used in the construction industry (e.g. for plasters, mortars and sealants), in the packaging industry and in the production of textile coatings.
