| Low-molecular rubber PDI-3AK
Produced according to TU 38.103410-85 with amendment 6.
It is a polydiene urethane with end epoxy groups.
It is used as an elastic binder for pourable sealing and impregnating compositions as well as for compounds to be used in electronic, electrical and radio industries, sealants, adhesives, surfacers, in floor covers in sport premises, as elastic epoxy resin. It shows high adhesion to metals, concrete, wood, glass. It is chemically resistant to diluted acids and alkalis. It is remarkable for its higher electrical properties and frost resistance as the set compositions retain their resilience up to -50 OC.
It is soluble in gasoline, xylene fraction, chlorated hydrocarbons.
