The influence of the type of organic solvent, the acidity index, and the content of MF-12 methylphenyl organosilicon oligomer on the gelation time during polycondensation for the manufacture of heat-resistant electrical insulating materials is considered. The choice of the type of solvent that provides the best viscosity characteristics during impregnation and the greatest stability of the properties of the binder intended for use in combination with selective latent polycondensation catalysts, which exclude the effects of undesirable processes in the production and storage of pre-impregnated materials, has been justified.
