Abstract
Abstract An expansion agent comprising a foamable mixture of (a) 15-53 weight % of a foaming agent having 6 to 78 carbon atoms selected from the group of an ammonium salt, aliphatic amine salt and/or an alkali metal salt of an alkyl sulfate, hydroxyalkyl sulfate, alkyl ether sulfate and/or aryl alkyl ether sulfate; (b) 5-42 weight % of a dispersant having 22 to 260 carbon atoms selected from the group of an alkyl alkyleneoxy amine and/or its quaternary alkylsulfate, alkylhalide or alkylphosphate derivative; and (c) 5-40 weight % of a stabilizer having 8 to 68 carbon atoms selected from the group of a sodium and/or potassium salt of an alkyl sulfosuccinate; and the combination of said mixture with a synthetic resin, latex or natural rubber to provide a coating or finishing composition; the process of applying said composition to a substrate and the treated substrate product having incorporated the composition of the invention.
