Coatings may be used to discourage agglomeration and dust formation when handling seeds. Aqueous emulsions suitable for coating seeds and other substrates may comprise an aqueous fluid, a film-forming polymer that is water-soluble or biodegradable, optionally, a plasticizer, and shellac particles dispersed in solid form in the aqueous fluid. The film-forming polymer is at least partially dissolved in the aqueous fluid. Optionally, the aqueous emulsions may comprise at least one effect pigment, and/or at least one wax, and/or one or more of at least one surfactant, at least one biocide, at least one preservative, at least one second film-forming polymer, at least one crosslinking agent, or any combination thereof.

A method for forming a water, oil, and/or gas resistant and/or impermeable product. The method includes (a) coating a product with a composition, the composition including: a protein, wherein the protein, is a plant-derived protein, an animal-derived protein, a fungus-derived protein, or any combination thereof; and/or shellac; and (b) heating the coated product. The coated product may be heated to temperatures in excess of the ignition temperature of the uncoated product and/or in excess of the thermal degradation temperature of the protein and/or shellac (e.g. to temperatures between 200 C. and 300 C.) without damaging the coated product. Water, oil, and/or gas resistant and/or impermeable products formed by the method may includes cellulose-based products such as a paper-, cardboard- or wood-based products. The products may form part of or all of a container for use in the food and beverages industry or an item of cutlery.
