One-part foamable latex composition

摘要

A single-component foamable latex composition, the method of preparing the composition, and the foams prepared therefrom, which composition comprises a natural or synthetic latex or blends, ammonia, a curing system, a siloxane heat-sensitizing agent, and a zinc dibenzyl dithio carbamate accelerator. The latex composition is capable of being stored for a long period of time without gellation or precure prior to use. The combination of a heat-sensitizing agent and an ammonia-retardant accelerating agent has been found to prevent premature gellation and precure of the latex composition.
