The aim of the study was to compare the strength of adhesive joints bonded with two different UV-cured adhesives in different exposure times. The adhesives used in the research differed in viscosity. The first adhesive Multibond 5550 was characterised by low viscosity, the second adhesive Multibond 5544 was characterised by high viscosity. The adhesive joints were made from a 316L steel sample and a sample made from polymethyl methacrylate. The adhesive joints were cured at three time intervals: 5 minutes, 10 minutes and 20 minutes. The strength of the adhesive bonds was compared using the MANOVA test. Statistical analysis showed that there was a statistical difference between the adhesives cured for 10 minutes. It was also found that joints where a high viscosity adhesive was used showed similar strength results for 10 and 20 minutes of adhesive exposure to UV rays. Statistical analysis was performed using RStudio software and the R programming language.
