Acrylic polyester resin and an aqueous coating composition containing the same

There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms. At least one of the polyacid component and/or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a packaging coated with the composition.

BIOFOULING RESISTANT COATINGS AND METHODS OF MAKING AND USING THE SAME

Disclosed herein are compositions to use in biofouling-resistant coatings, biofouling-resistant coatings, methods of making biofouling-resistant coatings, biofouling-resistant devices, and methods of making biofouling-resistant devices.

ARTICLES INCLUDING COATED FIBERS AND METHODS OF MAKING COATED FIBERS AND ARTICLES

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.

IRRADIATION-CURABLE POLYOLEFIN FORMULATION

An (electron beam)-curable (EBC) formulation comprising an EBC polyolefin compound having a crystallinity of from 0 to less than 50 weight percent (wt %) and/or having a density of 0.930 gram per cubic centimeter (g/cm.sup.3) or less; and an alkenyl-functional monocyclic organosiloxane (“silicon-based coagent”). Also included are a cured polyolefin product prepared by electron-beam irradiating the EBC formulation; methods of making and using the EBC formulation or cured polyolefin product; and articles containing or made from the EBC formulation or cured polyolefin product.

PROCESS FOR PRODUCING A COMPOSITION COMPRISING A CROSSLINKED HYDROGEL
20230002564 · 2023-01-05 ·

A process for producing a composition comprising a crosslinked hydrogel is proposed. The process comprises providing a container body (2), wherein the container body (2) has a body inner wall (21) and a body outer wall (22), wherein the body inner (21) wall is configured to be tempered, filling of a fluid (7) comprising at least a mixture of a polymer and water into the container body (2), and agitating the fluid. For crosslinking of the fluid (7), a container insert (3) is provided, the container insert (3) having an insert outer wall (32) which is configured to be tempered and a container assembly (1) is formed by inserting the container insert (3) into the container body (2) so that the insert outer wall (32) of the container insert (3) and the body inner wall (21) of the container body (2) are separated by a gap (9) of constant width and define a volume (6) for receiving the fluid (7). Crosslinking of the fluid (7) is then performed while tempering the insert outer wall (32) and the body inner wall (21) to form a crosslinked hydrogel.

SYSTEM FOR PRODUCING A FULLY IMPREGNATED THERMOPLASTIC PREPREG

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.
