The term 'permeates' is used to describe the process of something entering and spreading throughout a substance or material. It can be done in a variety of ways, such as invading, imbuing, seeping, imbruing, and interpenetrating. To invade is to enter forcefully and spread throughout, while imbuing is to fill with a quality or character. Seeping is the gradual infiltration of a liquid into a porous material, while imbruing is to saturate or stain with a color or quality. Finally, interpenetrating is to penetrate deeply and thoroughly. All of these terms are related to the concept of permeation, which is the process of something entering and spreading throughout a substance or material.
