Abstract
A method of using a water-based boron-containing suspension as a source of boron additive is disclosed. The method includes adding the suspension into a mixing or reaction zone during the preparation of starch-based adhesives. The suspension includes a boron compound and at least one suspension aid.
Claims25
A method of using a water-based boron-containing suspension as a source of boron additive in a starch-based adhesive, said water-based boron-containing suspension being substantially free of organic solvent(s), said method comprising introducing said water-based boron-containing suspension into a mixing or reaction zone during the preparation of said starch-based adhesive.
An aqueous starch-based adhesive, comprising:
- a) water;
- b) starch;
- c) caustic soda;
- and
- d) from about 0.05 wt % to about 10 wt % a water-based boron-containing suspension that is substantially free of organic solvent(s).
A method of using a water-based boron-containing suspension as a source of boron additive in a starch-based adhesive, said method comprising introducing said water-based boron-containing suspension into a mixing or reaction zone during the preparation of said starch-based adhesive, said starch-based adhesive exhibiting wet bond strength characterized by percentage fiber tear of at least about 50% estimated after wet pin bond strength test.
An article of commerce, comprising a container that contains a water-based boron-containing suspension, said water-based boron-containing suspension being substantially free of organic solvent(s), said container bearing an instruction to use said suspension in a starch-based adhesive.
