| 摘要 |
FIELD: chemical industry. SUBSTANCE: present invention describes cleaning liquid compositions and method of removing contaminations from substrate, e.g. printed circuit board. The claimed composition or variant thereof comprises solvating agents/detergents. Solvating agents are selected from group consisting of terpenes and terpene based compounds and detergents from group containing chlorinated hydrocarbons, chlorofluorcarbons, fluorocarbons, fluorohydrocarbons, chlorofluorohydrocarbons, alcohols, fluorinated alcohols or mixtures thereof. Composition comprises inflammable solvating agents. Claimed method of removing contaminations, e.g. soldering rosin flux from printing circuit, comprises contacting it with boiling composition containing solvating agents and detergents. EFFECT: improved properties of the cleaning composition. 33 cl, 1 dwg , 1 tblk
