A heat curable, polyester type impregnating composition is made, containing acid, and hydroxyl components containing fluorinated alcohol and non-fluorinated polyol, and where a fluorinated aliphatic alcohol having a perfluoroalkyl group from 4 carbon atoms to 12 carbon atoms constitutes from 1 wt. % to about 40 wt. % of the total fluorinated alcohol plus non-fluorinated polyol content of the composition, the composition being useful to impregnate porous tapes wrapped around electrical conductors, or to impregnate porous substrates used to make laminates, the impregnate upon cure imparting water and flame repellent characteristics.
