👉 A filing fluid, also known as a drafting fluid or drafting ink, is a specialized liquid used primarily in the field of drafting and technical drawing. It's designed to provide a smooth, consistent, and non-sticky surface for transferring pencil or pen lines onto paper or other media. This fluid typically contains solvents and additives that help it flow easily, adhere well to surfaces, and dry quickly without leaving streaks or residue. It's particularly useful for creating clean, precise lines and for maintaining the integrity of the drawing when multiple layers are applied. Filing fluids come in various viscosities and formulations, catering to different needs and preferences among drafters.
