Abstract
Highly-plasticized cellulose esters may be useful as adhesives, including for use in producing laminates. For example, producing a laminate may include providing an adhesive melt that comprises an adhesive that comprises a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 75% by weight of the adhesive; applying the adhesive melt to a substrate; and allowing the adhesive melt to cool so as to yield a laminate on the substrate.
Claims19
A method comprising:
- providing an adhesive melt that comprises an adhesive that comprises a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 75% by weight of the adhesive;
- applying the adhesive melt to a substrate;
- and
- allowing the adhesive melt to cool so as to yield a laminate on the substrate.
1 more element
A method comprising:
- compounding at least a cellulose ester and a plasticizer to yield an adhesive melt, the plasticizer included in an amount of about 30% to about 75% by weight of the adhesive melt;
- applying the adhesive melt to a substrate;
- allowing the adhesive melt to cool so as to yield a laminate on the substrate;
- and
- treating the laminate with at least one selected from the group consisting of heat, vacuum, a caustic bath, and any combination thereof.
