Abstract: A mold release sheet structure in medium to high pressure laminate wherein the laminate comprises a film of polyester, nylon or cellulose acetate treated for promoting resin adhesion and having a coating of a thin release layer of a cured release acrylated oligomer resin on at least one side of the film.

Abstract: A method and apparatus for coating non-woven and other porous webs and the like with controlled or negligible penetration into the pores by subjecting a coating carried by a surface to electron beam radiation before laminating the web to the surface carrying the coating and with a radiation dose that only partially cures the coating into a soft or tacky state such that the laminating will effect surface spreading adhesion to the web with controlled or substantially no penetration into the pores, and thereafter subjecting the laminated web and partially cured coating to greater electron beam radiation fully to cure the coating.

Abstract: This disclosure is concerned with a method of transfer-coating electron-beam-curable materials, by applying such materials to the surface of a cooled drum, either through a sheet or web carrying the same over the drum or from the drum surface itself, curing the material against the drum at a region of electron-beam radiation directed thereupon and releasing the cured material from the drum surface; and with the latter, where desired, reflecting radiation back into the material being cured.
