Performance Differences and Characteristic Comparison of Three Glues
The three common adhesives have distinct performance positioning for different scenarios. Epoxy AB glue features high hardness and high shear resistance, ideal for fixed structural bonding and heavy-load fixation, but it lacks toughness and may crack under strong impact. Polyurethane AB glue excels in toughness and shock absorption, with good deformation resistance, suitable for dynamic and flexible bonding scenarios, though its surface hardness is relatively low.
Crystal glue has outstanding transparency and decorative effects but low structural strength, not applicable for load-bearing bonding. In terms of weather resistance, polyurethane glue fits outdoor use best, epoxy glue is suitable for indoor industrial use, and crystal glue is mainly for indoor decoration.
