The present invention relates to a starch-based adhesive composition for use in cigarette manufacture. The adhesive composition includes at least about 2 percent of a unmodified dispersible starch that thickens on heating to a temperature greater than about 50.degree. C.; 2-25 percent modified starch and a rheology modifier.
摘要:
A process for preparing novel composite structures by priming the surfaces of two or more substrates (such as SMC panels, etc.) with an effective amount of an epoxy resin prior to adhering said surfaces together with an adhesive (such as a polyurethane adhesive) wherein said structures have improved high temperature (about 400.degree. F.) tolerance is described.
摘要:
