Produced according to TU 38.103342-88 with amendment 1,2.

It is an oligomer with end hydroxyl groups produced by divinyl-isoprene copolymerization. It is used for pourable sealing and impregnating compositions: sealants, adhesives, surfaces, in floor covers. PDI-1K based compounds are of good adhesiveness to metals, concrete, wood, glass, leather, rubbers, plastics.
It is chemically resistant toward weak acids and alkalis.
It is soluble in aromatic hydrocarbons, gasoline, chlororganic solvents.
