Abstract
Disclosed are silazane compounds having two fluoroalkyl groups, represented by the following general formula (1):wherein Rf and Rf′ are each a fluoroalkyl group, R1 is a hydrogen atoms or an aliphatic monovalent hydrocarbon group, R2 and R3 are each an aliphatic monovalent hydrocarbon group, R4 is a hydrogen atom or an aliphatic monovalent hydrocarbon group, a and b are each 0 or 1, m, n and p are each an integer of 0 to 6, q is an integer of 1 to 6, and r is 1 or 2. By treating an inorganic material with the silazane compound having two fluoroalkyl groups, high water and oil repellency and high sliding properties can be imparted to the inorganic material in good balance.
