Compositions for imparting desired properties to materials

A method of preparing a coated substrate which comprises:

• (1) coating a substrate with a coating composition comprising:
• (A) at least one water-soluble component comprising at least one functional group that undergoes a crosslinking reaction;
• and (B) at least one film-forming polymer;
• and
• (2) curing the coating composition on the substrate.

A method of preparing cellulosic products which comprises:

• substantially simultaneously or sequentially adding to a system comprising cellulosic fibers,
• wherein the system is selected from at least one of aqueous system, felt, web, and combinations thereof
• (A) at least one water-soluble component comprising at least one functional group that undergoes a crosslinking reaction;
• and (B) at least one film-forming polymer.

A method for forming a substantially chromium-free, dried in place conversion coating on a metal surface comprising applying to a metal surface:

• (1) an aqueous composition comprising (A) at least one water-soluble component comprising at least one functional group that undergoes a crosslinking reaction;
• and (B) at least one film-forming polymer;
• and
• (2) fluoacid,
• wherein the amount of the composition in (1) is from about 0.1 to about 90% by weight, and
• wherein the amount of fluoacid is from about 0.2 to about 20% by weight.

A method of producing a coated substrate comprising

• (1) coating a substrate with a coating composition comprising:

• and
• (B) at least one material in an amount sufficient to impart a cuttability value of less than about 15 to the coated substrate upon curing the coating composition;
• and
• (2) curing the coating composition on the substrate.
