High boiling point aromatic hydrocarbon solvent is developed and produced according to international special aromatic hydrocarbon solvent standards. It has strong solubility, low toxicity, low odor, high boiling point, slow volatilization, no water and olefins, and no Chlorine and heavy metals, stable chemical and physical properties, good leveling, excellent solubility, etc., especially in the post-evaporation stage can exert high solubility, make the coating film smooth without orange peel, good luster. In addition, it can also be used as a cleaning agent for precision machinery and a pesticide emulsifier.
