Parachlorobenzotrifluoride is an organic chemical compound with the molecular formula C7H4ClF3. It is frequently abbreviated PCBTF. Parachlorobenzotrifluoride is a colorless liquid with a distinct aromatic odor. It is used as an ink solvent in the printing industry. PCBTF is used as a component (5-12%) of low VOC compliant polyurethane finishes.[1] It is sold under the brand name Oxsol 100[2] and SMC Spec 900 [3]. The material itself is considered to have negligible VOCs and is increasingly used as a Xylene replacement in cleaners, thinners and other aromatic hydrocarbon blends.

Uses

Parachlorobenzotrifluoride has a high capacity for dissolving many inks used by the printing industry. In most cases, up to 22 grams of ink[4] can be dissolved in 20 grams of PCBTF. An added benefit is that parachlorobenzotrifluoride dissolves most inks faster than toluene.
