Abstract
Described herein are coatings which impart oil, grease, and water resistance to various materials, such as paper, paperboard and polymeric materials. Such coatings may be applied as barrier coatings to the substrate materials in order to inhibit and prevent the transmission of oil, grease and water; that is, to prevent oil, water grease from passing into and/or through the substrate material. The coatings include an acrylic-based polymer latex, a styrene-butadiene rubber latex, a styrene-acrylic resin solution, a large particle size wax, and optionally, a small particle size wax. Also disclosed herein is a process of preparing the coatings. Also disclosed are products to which the coatings have been applied in order to impart oil, grease and/or water resistance, and processes for preparing such products.
