BINDER COMPOSITIONS WITH POLYVALENT PHOSPHORUS CROSSLINKING AGENTS
20210261811 · 2021-08-26 ·

An fibrous insulation product is provided that includes a binder comprising a polyol and a phosphorus crosslinking agent derived from a phosphonic or phosphoric acid, salt, ester or anhydride to form crosslinked phosphodiester linkages. The polyol is polyvalent, but may be monomeric or preferably polymeric; and may be synthetic or natural in origin. Carbohydrate polysaccharides are exemplary polyols, including water-soluble polysaccharides such as dextrin, maltodextrin, starch, modified starch, etc. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In exemplary embodiments, the binder may also include a catalyst, a coupling agent, a process aid, and other additives. The environmentally friendly, formaldehyde-free binder may be used in the formation of residential and commercial insulation materials and non-woven chopped strand mats. A method of making fibrous products is also provided.

BIODEGRADABLE OMNIPHOBIC AND HIGH-BARRIER COATINGS, RELATED ARTICLES, AND RELATED METHODS
20210246333 · 2021-08-12 ·

The disclosure relates to omniphobic coatings, related articles including such coatings, and related method for forming such coatings or articles, for example biobased and/or biodegradable omniphobic coatings with high barrier properties. The omniphobic coating includes an oleophobic and hydrophilic first layer, and a hydrophobic and optionally oleophilic second layer adjacent to the first layer. A corresponding omniphobic coated article can include the omniphobic coating on a substrate such as a porous cellulosic or paper substrate, for example to provide a water- and oil/fat/grease-resistant coating for a paper-based product. The first layer of the omniphobic coating is adjacent to the substrate and the second layer is adjacent to the first layer at a position further from the substrate than the first layer. The omniphobic coating can be applied to a substrate in a layer-by-layer process, and the coated article can be recycled by extraction to remove the coating and recover the substrate material, for example in a re-pulping process.

Moisture, Grease, and Oil Resistant Coatings for Cellulosic Materials
20210292590 · 2021-09-23 ·

A coated cellulose-based food or beverage container that is resistant to penetration by oil and grease in the presence of water. The container may be coated with a starch dispersion that includes a starch having an amylose content of 20% by weight to 100% by weight (e.g., 30% by weight to 50% by weight). Methods for producing the coated container include preparing a starch suspension, heating the starch suspension to form a starch dispersion, applying the heated starch dispersion to the container to form a coating, and drying the coating.
