Investigation of Polyurethane Adhesives for Use in the Apache Aviator NBC Protective Mask

摘要

Polyurethane adhesives are currently used in Apache aviator masks to secure polycarbonate lenses to a bromobutyl-natural rubber face piece.This study examined the rupture behavior of polycarbonate(pc)components bonded to butyl-rubber with polyurethane adhesives.Composite were fabricated and destructively tested to reveal differences in failure mode and rupture strength as a function of surface preparation,curing regime,and polyisocyanate-polyol formulations.
