Adhesive for polystyrene. Dissolve small pieces of polystyrene in benzene, trichlorethylene or carbon tetrachloride. Dissolution can be greatly accelerated, using instead of hard polystyrene, expanded polystyrene, the so-called. polystyrene. The glue should be thin, because it is thick when spreading and pulls into threads. Store in a tightly closed vessel, preferably in a jar with a polyethylene or polyamide cap. This glue, due to the excellent insulating properties of polystyrene, suitable for impregnating small details used in electrotechnical works.
