PURPOSE:To eliminate adverse effect on an urethane molding even when an agent for removing attached matters is left on a die face after used by arranging polyol into a solvent for removing attached matters to specify the viscosity by thickening. CONSTITUTION:A surfactant, water and polyol are arranged into a solvent to set the viscosity at 100-1,000cps. The adjustment of the viscosity allows the agent for removing attached agent to prevent run-down thereof and the volatilization of the solvent after it is applied to an urethane molding die face 5, which promotes the cleaning effect thereof maintaining a wet condition while attached matters such as releasing agent are dissolved and swelled. Since polyol is one of main urethane components, polyol still left slightly on the die face will not adversely effect the urethane molding after attached matters are removed by the agent for removing attached matters. |
