Kovettimia

Kovettimia is a Finnish term that broadly refers to hardening agents or hardeners. In a technical context, it most commonly describes substances used to increase the hardness, durability, and strength of materials. The specific type of kovettimia depends heavily on the material being treated and the desired outcome.

One significant application of kovettimia is in the field of polymers and resins. Epoxy resins, for example, require a hardener to cure and achieve their solid, robust state. These hardeners react with the epoxy molecules, creating cross-links that form a rigid network. Similarly, certain plastics and rubbers undergo a hardening process, often through the addition of specific chemicals, to improve their mechanical properties and resistance to wear.

In metallurgy, kovettimia can refer to elements or processes that harden metals. Heat treatment processes like quenching and tempering are designed to alter the microstructure of metals, making them harder and stronger. While not always a direct additive in the same way as polymer hardeners, the underlying principle of increasing material resistance to deformation is similar. The term can also be used in a more general sense to describe anything that makes a substance harder or more resistant to external forces.
