Paksuuntumaa

Paksuuntumaa is a Finnish noun that denotes the phenomenon or process by which a liquid or soft material becomes thicker, that is, an increase in viscosity. It can refer to both the process itself (paksuuntuminen) and the observable thickened state in technical or everyday usage. The term is formed from paksu, meaning thick, and the abstract noun suffix -untuma, which indicates a condition or characteristic.

In scientific and engineering contexts, paksuuntumaa is used primarily in rheology, polymer science, food technology, and materials processing to describe thickening caused by factors such as cross-linking and network formation in polymers, coagulation, concentration of solids, or temperature, pH, and other processing conditions that promote a denser phase. It can describe thickening in emulsions or gels, where a network structure increases viscosity, or a practical observation during processing when a mixture becomes noticeably thicker.

The term is relatively specialized in Finnish. In many contexts, more precise language is used, such as viscosity increase or gelation, depending on the underlying mechanism. English translations vary with context and may include thickening phenomenon or thickening, though there is no single exact equivalent for all uses.
