Abstract
An adhesive composition including at least 7% and at most 30% by weight of adhesive component, which adhesive component includes at least one polyvinyl alcohol and/or at least one dextrin and/or at least one starch, further including a carbomer and optionally a boron compound, wherein the pH of the composition is at most 13.0 and, if starch and the boron compound are present, more than 91.0% of all the starches in the composition are in a cold water insoluble form. Further provided are a solid dry premix suitable as the basis for the adhesive composition, and processes for preparing the solid dry premix, or the adhesive composition, and articles wherein any of these are employed to form an adhesive bond with a substrate.
Claims33
An aqueous adhesive composition comprising at least 7% and at most 30% by weight, based on the total adhesive composition, of adhesive component, the adhesive component comprising at least one component selected from the group consisting of a polyvinyl alcohol, a dextrin, a starch, and mixtures thereof, the adhesive composition further comprising a carbomer and optionally a boron compound, whereby the carbomer is cross-linked, whereby the adhesive composition has a pH of at most 13.0 and whereby, if starch and the boron compound are present in the adhesive composition, more than 91.0% of all the starches in the composition are in a cold water insoluble form.
A solid dry premix composition comprising (i) at least one adhesive component selected from the group consisting of a polyvinyl alcohol, a dextrin and a starch, and mixtures thereof, (ii) a carbomer and (iii) a base, and optionally a boron compound, whereby the carbomer is cross-linked, and whereby, if starch and the boron compound are present in the composition, more than 91.0% of all the starches in the composition are in a cold water insoluble form.
