DIAZABICYCLO AND TRIAZABICYCLO PRIMER COMPOSITIONS AND USE THEREOF IN BONDING NON-POLAR SUBSTRATES

摘要

In a process for priming a non-polar substrate such as a polyolefin forbonding with a cyanoacrylate adhesive, the use of an adhesion-promoting primer comprising at least one diazabicyclo or triazabicyclo compound selected from 1,5-diazabicyclo ¢4.3.0! non-5-ene having the formula: (I) 1,8-diazabicyclo ¢5.4.0! undec-7-ene having the formula: (II) and 1,5,7-triazabicyclo ¢4.4.0! dec-5-ene having the formula: (III) The primer also contains a solvent.
