Again, it is not certain if this represents the beginning of a consistent trend, as the 10-week values were the last data points gathered. For the most part, transfer ratings throughout the study ranged from a 4 to a 5. As with transfer, although there were some statistically significant differences observed, these were not practically significant. Effect of Time Using Real-Time Aging Conditions. Data has been collected after periods of 6 months and 12 months.
All adhesive properties are stable.
As with the accelerated-aging evaluation, statistical analysis reveals significant differences in some of the properties. Validation of Accelerated Aging Conditions. As yet, an insufficient amount of data has been generated regarding the effects of real-time aging. Therefore, it is not possible to validate the effectiveness of the accelerated-aging conditions. Data generated after 6 months and 12 months of real-time aging correlate well with data generated after 1 and 2 weeks of accelerated aging.
