High-boiling aromatic solvents
Paint chemicals 2025-03-21
The naphthalene content in the product has strict requirements. High-boiling point aromatic solvent adopts the aromatic separation Technology of Tianjin University. It is obtained through distillation, freezing and centrifugation, which is more complicated than the common model, but is more environmentally friendly.
Possessing good solvency, low toxicity, free of chlorine and heavy metals, stable chemical and physical properties.
