Crystal Violet Lactone (CVL) CAS 1552-42-7 is a high-performance, widely used leuco dye for pressure-sensitive and thermochromic materials. It is a key color-forming agent that produces an intense blue-violet color when exposed to acid, heat, or pressure. In its neutral state, it is colorless or pale, but upon stimulation, its lactone ring opens to form stable, vivid color compounds, making it ideal for applications like carbonless copy paper and thermal printing.
Metal working fluid, also known as cutting fluid, is an essential industrial liquid widely used in metal cutting, grinding, stamping, drilling and rolling processes. In actual production, metal working fluid mainly undertakes four critical functions: lubrication, cooling, rust prevention and microbial protection. It effectively reduces friction between tools and workpieces, lowers cutting temperature, avoids metal oxidation and corrosion, and suppresses bacteria and mold reproduction inside the fluid system.Therefore, high-quality chemical additives including rust inhibitors, lubricants and industrial biocides become indispensable raw materials to maintain stable fluid performance.
