bindstof

Bindstof is a substance used to hold together particles, fibers, or droplets within a material, forming a cohesive structure. It functions as a binder or binding agent, enabling powders, liquids, or semi-solid components to be transformed into solids, pastes, or films. Bindstof can be inorganic or organic, and may be natural or synthetic.

Inorganic binders include cement, lime, and gypsum, which set through hydration or crystallization and are widely used in construction and ceramics. Organic binders encompass natural polymers such as starch, cellulose derivatives, proteins (casein), and alginates, as well as synthetic polymers like polyvinyl acetate, acrylics, and polyurethane. Some binders cure by crosslinking, others by gelation or film formation. The performance of a binder depends on its bonding with the substrate, moisture sensitivity, curing mechanism, temperature stability, and aging behavior.

Industrial uses include concrete and mortars, tile adhesives and plasters, paints and coatings, paper and textile sizing, adhesives and laminates, and food products as thickeners or texturizers. In each case, the binder contributes cohesion, adhesion, and mechanical strength, often working with fillers, pigments, and plastifiers.

Regulatory and safety considerations vary by application. In construction and coatings, binders must meet standards for compressive strength, durability, and fire resistance. In food and pharmaceuticals, binders are subject to purity and safety regulations and may require labeling. Some binders can pose inhalation or skin contact hazards, and solvent-based systems raise volatility concerns.
