Abstract
A product and method comprising a cellulose based release layer. The cellulose release layer comprising cellulose particles having at least one dimension in the nanoscale range. The cellulose release layer being between a mold surface and moldable mixture surface during a molding process. The method comprising releasing a moldable mixture from a mold where the moldable mixture may include a pre-adhesive. A molded product comprising a release layer on its surface after molding.
Claims19
A method comprising:
- molding a moldable mixture with a mold, the moldable mixture comprising a pre-adhesive that forms a thermoset adhesive,
- wherein a release layer is between the moldable mixture and the mold, and the release layer comprises a surface density from about 0.016 g/m2 to about 4.3 g/m2 dry weight cellulose particles and the cellulose particles have an average size of 100 nm or smaller in at least one dimension.
A method comprising molding a moldable mixture with a mold wherein a release layer is between the moldable mixture and the mold, the release layer comprises a surface density from about 0.016 g/m2 to about 4.3 g/m2 dry weight cellulose particles and the cellulose particles have an average size of 100 nm or smaller in at least one dimension.
A product comprising (i) a molded composite having a matrix and a thermoset adhesive, and (ii) a layer of cellulose particles at least partially covering a surface of the composite, the layer of cellulose particles having a surface density from about 0.016 g/m2 to about 4.3 g/m2 dry weight cellulose particles and the cellulose particles having an average size of 100 nm or smaller in at least one dimension.
