Abstract:
The present disclosure pertains to a process for preparing a laminate comprising: providing a dried overlay and a base sheet wherein at least one of the dried overlay and the base sheet comprises a resin-impregnated, opaque, cellulose pulp-based sheet; applying a fluorourethane to the dried overlay to form a treated overlay; drying the treated overlay; and laminating the treated overlay to the base sheet. The disclosed process hereby produces a laminate whose outer surface is modified with the fluorourethane and the cleanability, oil repellency, and abrasion resistance of such a laminate is improved.
