A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

The invention relates to a method for producing a finished leather substitute, which method comprises providing a sheet material grown from mycelium, which sheet material shows a top surface layer and a bottom surface, wherein the method comprises applying at least one finishing coating on the bottom surface only.

In a first embodiment, the invention provides a composite fabric which contains a first fabric layer and a thin film. The first fabric layer has an upper and lower side and contains a plurality of synthetic polymer fibers. The synthetic polymer fibers contain at least 15% of bio-based carbon content as measured by ASTM D26866-20 Method B. The thin film is located on the lower side of the first fabric layer and contains at least 15% of biobased carbon content as measured by ASTM D26866-20 Method B. The thin film has an average weight of less than about 30 GSM and has an air permeability of less than about 1 CFM as measured by ASTM D737 @ 125 Pa.

Devices and methods related to a chitosan-enhanced melamine sponge are provided. A method comprises grafting chitosan on the melamine sponge matrix via the chemical with two or more carboxyl groups; and crosslinking the chitosan with crosslinker under a heating procedure to make a more robust melamine sponge with a larger surface and smaller pores. The chitosan-enhanced melamine sponge is used to separate chemicals from water as a gravity flow-driven filter, and it can be compressed and backwashed for regeneration.

Coated nonwoven fibrous mats, building panels, and methods for making the same are provided. A coated nonwoven fiber mat includes a nonwoven fibrous mat having a continuous barrier coating on a surface thereof. The continuous barrier coating includes a set composition of gypsum and a binder. A building panel includes a panel core associated with a coated nonwoven fiber mat. A method of making a coated nonwoven fibrous mat includes depositing a composition of water, gypsum stucco, and a binder onto a surface of a nonwoven fibrous mat and setting the composition to form a continuous barrier coating.

The invention relates to a sealing element comprising at least 20-60 wt % of PVC resin, and 20-45 wt % of a biobased plasticizer.

An encapsulant material for a photovoltaic module. The encapsulant material includes: between 30 and 50 parts by weight of fiber cloth, and between 50 and 70 parts by weight of a polyester powder coating. The polyester powder coating includes a polyester resin and a curing agent. The polyester resin is a polymer of monomers selected from terephthalic acid, m-phthalic acid, neopentyl glycol, adipic acid, ethylene glycol, or a mixture thereof. The curing agent accounts for 2-20 wt. % of the polyester powder coating. The polyester powder coating is evenly distributed on the fiber cloth. A method of preparing the packaging material includes: evenly distributing the polyester powder coating on the fiber cloth using a coating device; and thermally bonding the polyester powder coating and the fiber cloth.
