いう欠点を有しており、長期間の使用に耐えられないも
のであった。However, the method of applying oil with excellent mold releasability and lubricity has the disadvantage that the applied oil is lost from the surface over time and its effectiveness gradually decreases. In addition, the method of applying and curing silicone resin, which has mold releasability and lubricity, does not allow the cured resin film to continue to stretch the rubber material. It has the drawbacks of easy cracking, loss of mold releasability and lubricity, and an unfavorable appearance, and cannot withstand long-term use.

The tensile elongation of this composition was measured in the same manner as in Example 1, and a value of 35% was obtained. This composition is mixed into urethane rubber and ethylene propylene rubber (E
P rubber) to form a cured film, and its peel resistance and dynamic friction coefficient were evaluated in the same manner as in Example t, and the results shown in Table 2 were obtained.

The mixture was flow-coated onto a fluororubber plate, left at room temperature for 30 minutes, and then heated at 150'C for 30 minutes to form a cured film. When this plate was bent by hand, microcracks occurred at the bent portion, and when the plate was returned to its original position, the bent portion turned white. Other surface properties were evaluated in the same manner as in Example 1, and the results shown in Table 4 were obtained. Furthermore, this resin film alone was extremely hard and brittle, so it was not possible to measure its elongation.
