vesipõhised

Vesipõhised is in Estonian usage a term that describes products, formulations or processes in which water is the primary solvent or medium. The label is commonly attached to paints, coatings, inks, adhesives, cleaners and some cosmetic or personal care products. In these systems, water acts as the vehicle that suspends and transports ingredients during processing and application.

In paints and coatings, vesipõhised ref ers to latex or emulsion technologies where polymer particles are dispersed in water. After application, water evaporates and the polymer particles coalesce to form a continuous film. Typical ingredients include polymers, pigments, surfactants, coalescents and various additives to adjust flow, adhesion and cure. The exact formulation depends on the desired properties such as finish, hardness and resistance.

The main advantages of vesipõhised products are lower volatile organic compound (VOC) emissions, easier cleanup with water, reduced odor and often safer handling compared with solvent-based alternatives. They align with environmental and health regulations and consumer preference for greener products.

Limitations can include trade-offs in chemical resistance, durability under harsh conditions, and sensitivity to temperature or humidity during application and drying. Bonding to non-porous substrates may require primers, and curing times can be longer in cool or damp environments. Certain vesipõhised systems may also show different aging behavior under UV exposure.

Overall, vesipõhised coatings and formulations represent a dominant trend in many industries due to environmental considerations, while ongoing development seeks to close performance gaps relative to solvent-based options.
