Abstract

DEPCT64 09/06/2021 The present invention describes a customizable method of treating cellulosic materials with a barrier coating consisting of prolamine and at least one polyol. Fatty acid esters (polyol fatty acid esters) that provide increased oil and/or grease resistance to the material. without compromising its biodegradability, the method as revealed provides for the seizure. barrier coating on the work piece composed of cellulosic materials and workpieces made by that method. Therefore, the treated material shows higher hydrophobicity. and may be used in any application who want such features --------------------------------------------- -------------- DEPCT64 The present invention describes a customizable method of treating cellulosic materials with prolamine-containing barrier coatings ( prolamine) and at least one polyol fatty acid ester providing increased oil and/or grease resistance to the material by without compromising its biodegradability. The coating is bonded to a workpiece composed of a cellulosic material. and the workpieces made by that method. Therefore, the treated material shows a higher aversion. and may be used in any application requiring such properties. -------------------------------------------------- ---------
