Exploring the Efficacy of Adhesives in Plastic Bonding: A Comprehensive Experimental Analysis with Emphasis on PVC-P Conservation

Abstract

This research project conducted a comprehensive investigation into the long-term compatibility of six distinct adhesives with PVC-P plastic, a plastic material with a high degree of problematic characteristics in museum collections. Utilizing diverse metrics such as artificial accelerated ageing, radiography, and stress analysis through tensile testing, the study aimed to assess adhesive performance and reveal underlying interaction mechanisms. Statistical analysis provided significant insights into adhesive stress endurance, identifying the most suitable adhesive for PVC-P adhesive bonding from the tested adhesives. Among the six adhesives examined, Araldite 2020 consistently demonstrated the highest strength across all conditions tested. Nonetheless, upon consideration of reusability, ethical concerns, and environmental impact, Lascaux 498 HV emerges as the optimal adhesive for PVC-P among the tested six materials. While this project represents a significant step forward in our understanding of adhesive bonding of plastics, it also highlights the expansive scope for academic and scientific inquiry. By delving deeper into experimentation and evaluation, this project also paves the way for more informed conservation practices in the face of evolving materials and preservation challenges.
