A waterproofing agent composition comprises 100 parts by weight of the pine resin, 20 to 70 parts by weight of an expanded styrene resin, 1 to 10 parts by weight of a vinyl-based resin and 100 to 750 parts by weight of an organic solvent. The waterproofing agent composition is a liquid and exhibits superior adhesion to various materials, thus providing proofing characteristics, humidity resistance and permeability resistance to surfaces of various materials water. In addition, the waterproofing agent composition may provide heat insulation characteristics along with waterproofing characteristics, humidity resistance and permeability resistance to subjects or bases, thus being used for various purposes.

The present invention relates to synthesizing reduced graphene oxide on the surface of a metal sheet and glass. The invention particularly relates to a process for coating a substrate with reduced graphene oxide using seedlac as a carbon source. As per the process of the current invention, a solution of seedlac is prepared in an alcohol and the substrate is dipped in to the solution for one or more time. The substrate is then dried in air for 1-10 minutes and thereafter, heated to a temperature range of 400 to 1200 C. under controlled atmosphere of Ar/N.sub.2/ArH.sub.2/N.sub.2H.sub.2 at a different flow rate ranging from 100 to 500 seem for a period of 10 to 120 minutes.
