Abstract
A surface treatment composition comprising a crosslinking agent which comprises a plurality of dialdehyde residues, a water soluble polymer such as guar gum capable of covalently bonding with the crosslinking agent and a fibrous material.
Claims22
A surface treatment composition comprising a dry blended mixture that comprises:
- (a) a cross-linking agent in solid form comprising a plurality of residues of a dialdehyde, wherein said cross-linking agent comprises a solids content of at least 50 weight percent;
- (b) a water-soluble polymer capable of covalently bonding with said cross-linking agent, wherein said water-soluble polymer comprises guar gum;
- and
- (c) a fibrous material.

A surface treatment method comprising:
- (a) combining water and a surface treatment composition to thereby form an aqueous surface treatment mixture, wherein said surface treatment composition comprises a dry blended mixture that includes:
- (i) a cross-linking agent in solid form comprising a plurality of residues of a dialdehyde,
- (ii) a water-soluble polymer capable of covalently bonding with said cross-linking agent, wherein said water-soluble polymer comprises guar gum,
- (iii) a fibrous material;
- and
- (b) applying at least a portion of said aqueous surface treatment mixture to a target area.
3 more elements
A method of making a surface treatment composition, said method comprising:
- (a) heating a mixture comprising water and a dialdehyde to remove at least a portion of said water thereby forming a cross-linking agent in solid form, wherein said cross-linking agent comprises a solids content of at least 50 weight percent;
- (b) dry blending at least a portion of said cross-linking agent with a water-soluble polymer capable of covalently bonding with said cross-linking agent, wherein said water-soluble polymer comprises guar gum;
- and
- (c) blending a fibrous material with said cross-linking agent and said water-soluble polymer, wherein said fibrous material is blended before, after, or simultaneously with said water-soluble polymer.
