Stabilized methylene chloride formulation for vapor degreasing.

摘要

An improved stabilized methylene chloride composition useful in degreasing aluminum metal which contains as a stabilizer therefor either methyl or ethyl formate alone or mixtures thereof or a mixture of methyl formate and propylene oxide. The stabilizer is employed at a concentration of at least 1 percent by volume based on the methylene chloride when the mixture of formates is used. Amounts of 1.4 to 2.0 are required when other combinations or a single stabilizer component are used.
