compositions elestomeriche fluid, reticolabili to the humidity environment, suitable for use in sealants

摘要

Elastomeric fluid compositions, crosslinking in the presence of ambient humidity, contain: A) an elastomeric polymer constituted by an elastomeric basis of aliphatic polycarbonate; B) an organic compound containing in its molecule at least two N=C @ groups, selected from bisketimines, bisketiminoenamines and bisketiminosilazanes; C) a tertiary amine with stressed nitrogen and containing a carbon atom bonded to nitrogen a preferably a bicyclic ketimine. e
