A siloxane polymer composition includes an organic solvent in an amount of about 93 percent by weight to about 98 percent by weight, based on a total weight of the siloxane polymer composition, and a siloxane complex in an amount of about 2 percent by weight to about 7 percent by weight, based on the total weight of the siloxane polymer composition, the siloxane complex including a siloxane polymer with an introduced carboxylic acid and being represented by Formula 1 below, wherein each of R1, R2 R3, and R4 independently represents H, OH, CH3, C2H5, C3H7, C4H9 or C5H11, R′ represents CH2, C2H4, C3H6, C4H8, C5H10 or C6H12, and n represents a positive integer so the siloxane polymer of the siloxane complex has a number average molecular weight of about 4,000 to about 5,000.
