さらに改善が要求されている。BACKGROUND OF THE INVENTION Conventionally, various polyorganosiloxane compositions have been used as a treatment method for imparting non-adhesion to the surface of a base material such as paper, plastic, rubber and the like. These compounds were prepared by diluting a polyorganosiloxane having a hydroxyl group at a terminal with a polyorganosiloxane containing a Si—H bond and further adding an organotin compound with an organic solvent to obtain a compounded liquid. As this organic solvent, 1,1,1-trichloroethane was widely used because of its high incombustibility and volatility.However, because 1,1,1-trichloroethane is an ozone depleting substance, Is 1995
It will not be possible after the year. For this reason, alternative solvents have been studied, but none of them exhibiting sufficient performance has yet been provided. For example, when toluene, xylene, or the like, which is generally used as a coating solvent, is used, since the volatility is low, the solution is agglomerated or flows too much on the rubber surface to form a uniform film. In order to make it, it is necessary to reduce the amount of one application so that the solvent is sufficiently volatilized, which significantly lowers the working efficiency. In addition, n-hexane, n-heptane, n-
With octane etc., although these problems are somewhat improved, there are still problems with the coating effect and the uniformity of the coating film.
Further improvements are required.
