A release agent comprising a mixture of (A) a dimethylpolysiloxane and (B) an organopolysiloxane with phenolic hydroxyl groups, said mixture having an average phenol equivalent within the range of 10,000 to 5,000,000 and a dimethylsiloxane oligomer with less than 20 silicon atoms in an amount of less than 5,000 ppm, said agent having a viscosity within the range of 5 x 10<-5> to 1 x 10<-1> m<2>/s at 25 DEG C. The release agent of the present invention possesses excellent heat-resistant and release properties, and suppresses formation of formaldehyde under the effect of thermal decomposition. |
