Investigation of hygrothermal aging on the polyurethane-based (PUB) adhesive: substantiating competition scenario between sub-aging thermo-oxidation and hydrolytic phenomena

In this work, the effects of accelerated thermo-oxidative, hydrolytic and hygrothermal aging on the mechanical and chemical properties of a polyurethane based (PUB) adhesive are presented. The adhesive is extensively used in automobile industry particularly as a glass sealant. PUB is inevitably exposed to the hygrothermal environment during service life and the integrity of matrix interface is most vulnerable. This study focuses on weighing and...
