PURPOSE:To form a lubrication layer having high surface coverage and excellent frictional characteristic by incorporating two types or more of fluorine compounds having different average molecular weights of 500 of more of difference of the average molecular weights. CONSTITUTION:Two or more types of fluorine compounds 2, 3 having different average molecular weights of 500 or more of a difference of the average molecular weights are included. It is desirable to contain 80 - 20wt.% of fluorine compound 3 having a low molecular weight to 20 - 80wt.% of fluorine compound 3 having a high molecular weight in the fluorine compound. Thus, the compound 2 having the high molecular weight and the compound 3 having the low molecular weight are mixed so that the molecules of the compound 2 and the molecules of the compound 3 are mixed, fixed on a lubrication surface to generate a synergistic effect. In this manner, a lubrication layer which exhibits a high coverage even in a relatively low concentration, excellent frictional characteristic, water repellency, and oil repellency, can be formed. |
