ABSTRACT:
The invention relates to a quaternary ammonium salt primer for bonding surfaces with cyanoacrylate adhesives, and to a method of bonding surfaces using such quaternary ammonium compounds, particularly surfaces characterized by low surface energy values, such as polyolefins and rubber-modified polyolefins. A preferred quaternary salt is tetra n-butyl ammonium fluoride. Preferred solvents for the quaternary ammonium salt are non-aqueous, low surface tension organic solvents.
