Alkaline compositions useful to form aqueous paint stripping solutions are disclose which comprise mixtures of an alkali metal hydroxide, a polyoxyalkylene polyamine accelerator and, optionally, a glycol or glycol ether accelerator. The polyamine accelerator has the formula:
(R1)(R2)NXN(R1)(R2)
wherein R1 and R2 are selected from the group consisting of hydrogen, (lower)alkyl and [CH2CH(Y)O]mH, wherein Y is hydrogen or (lower)alkyl and m is about 1-4; and X is a polyoxy (lower) alkylene moiety.
公开了可用于形成脱漆水溶液的碱性组合物,它包括碱金属氢氧化物、聚氧亚烷基多胺促进剂和乙二醇或乙二醇醚促进剂的混合物。聚胺促进剂的化学式为
(r1)(r2)nxn(r1)(r2)
其中 R1 和 R2 选自由氢、(低级)烷基和 [CH2CH(Y)O]mH 组成的组,其中 Y 为氢或 (低级)烷基,m 约为 1-4;X 为聚氧(低级)亚烷基。
