Abstract
Abstract A novel water-repellent glazing agent is disclosed. The agent contains a modified organic silicone oil, which is represented by the general formula <IMAGE> wherein X1, X2 and X3 respectively stand for CH3 or a long chain alkyl group having 10-30 carbon atoms and at least one of X1, X2 and X3 is a long chain alkyl group having 10-30 carbon atoms and m and n are respectively 20-80 and 3-10. This agent has excellent water repellency and glazing effect as well as excellent operability.
