Abstract
The disclosure provides methods and compositions for coating substrates. A method of coating a substrate may include applying a formulation having a metal cation to a surface of the substrate to form a treated substrate, adding a solution having a biopolymer to the treated substrate, and allowing the biopolymer and the metal cation to react to form a coated substrate. The formulation may be applied to the substrate before the solution is added. A composition may include a reaction product of a biopolymer and a metal cation. The reaction product may be disposed on a coated substrate and the coated substrate may comprise a fibrous material.
Claims20
A method of coating a substrate, comprising:
- applying a formulation comprising a metal cation to a surface of the substrate to form a treated substrate,
- adding a solution comprising a biopolymer to the treated substrate, and
- allowing the biopolymer and the metal cation to react to form a coated substrate.
A coated substrate, comprising:
- a reaction product of a biopolymer and a metal cation, wherein the reaction product is disposed on a surface of the coated substrate, further wherein the coated substrate comprises a fibrous material comprising 8 wt. % or less of a filler.
A method of coating a substrate, comprising:
- applying a formulation comprising a metal cation to a surface of the substrate to form a treated substrate,
- contacting the formulation with a solution comprising a biopolymer, and
- allowing the biopolymer and the metal cation to react to form a coated substrate, wherein the coated substrate comprises less than about 8 wt. % of the metal cation.
