Disclosed is a paint composition containing graphene oxide for preventing corrosion of a structure and improving water repellency, corrosion proof and long-term durability of a concrete structure. The paint composition includes a powder mixture containing 0.2 to 1.0 weight % of zinc (Zn), 0.02 to 0.3 weight % of graphene oxide, 0.06 to 0.11 weight % of phosphorus, and a remaining amount of aluminum (Al); and an adhesive resin in which the powder mixture is uniformly dispersed.

Processes of making a non-woven glass fiber mat are described. The process may include forming an aqueous dispersion of fibers. The process may also include passing the dispersion through a mat forming screen to form a wet mat. The process may further include applying a carbohydrate binder composition to the wet mat to form a binder-containing wet mat. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The binder compositions may have a Brookfield viscosity of 7 to 50 centipoise at 20 C. The thickening agents may include modified celluloses such as hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and polysaccharides such as xanthan gum, guar gum, and starches. The process may include curing the binder-containing wet mat to form the non-woven glass fiber mat.
