Abstract
A process producing a foamed water-based adhesive is presented involving forming a foamable adhesive composition containing a polysaccharide modified with an alkyl succinic anhydride and then applying energy to said foamable adhesive composition to produce an adhesive foam.
Claims14
A process for producing a foamed water-based adhesive comprising:
- a) forming a foamable adhesive composition comprising:
- 1) a polysaccharide modified with an alkyl succinic anhydride;
- and
- 2) water,
- wherein said foamable adhesive composition has a viscosity of from 10 to 300,000 cps at 25° C., and
- b) applying energy to said foamable adhesive composition to produce a foamed adhesive.
