Kyllästeaineet

Kyllästeaineet, known in English as impregnating agents or saturants, are substances used to fill the pores or interstitial spaces within a material. Their primary purpose is to enhance the material's properties, such as its strength, durability, water resistance, or electrical insulation.

These agents are typically liquids that are applied to a porous material. The liquid then penetrates the pores through capillary action or pressure. Once inside, the impregnating agent is often cured, solidified, or otherwise fixed in place, either through chemical reaction, evaporation of a solvent, or temperature change.

Common applications for kyllästeaineet include the impregnation of wood to improve its resistance to decay, moisture, and insect attack. They are also used in the manufacturing of composite materials, where they bind reinforcing fibers together and fill any voids. In the electrical industry, impregnating agents are vital for insulating windings in motors, transformers, and other electrical equipment, preventing electrical breakdown and dissipating heat. They can also be used in textiles to impart water repellency or fire resistance. The specific type of kyllästeaine used depends heavily on the base material and the desired outcome. Examples include oils, resins, waxes, polymers, and various chemical solutions.
