Abstract

The present study was done to evaluate the effect of evaporation on the film thickness of two commercially available die spacers on three different surfaces. Die spacers used were Nice Fit and Durolan. Both die spacers were applied on three different surfaces—glass slide, die stone slab without hardener, and die stone slab with hardener after the bottles were left open for 0, 2, 4, 8, and 12 hours. The film thickness was measured with the help of SEM. Nice Fit die spacer showed an increase of 53, 139.5, 159.6, and 190.9% and Durolan showed an increase in 45.3, 142.6, 181.9, and 200% for 2, 4, 8, and 12 hours, respectively. Therefore, the number of coats must be reduced to achieve an ideal die spacer film thickness in the range of 25–40 μm. The thickness of die spacer on die stone slab without hardener was more compared to that on glass slide and on die stone slab coated with a hardener.
