Abstract
In this study we have investigated the effects of the chain length of hydrolyzable groups in two isocyanato silane coupling agents, 3-isocyanatopropyltrimethoxysilane and 3-isocyanatopropyltriethoxysilane, on the shear bond strength of resin attached to silicatized zirconia. In addition, the effects of varying the silane concentration (at 0.1 vol% and 1.0 vol%) with or without the addition of a cross-linking silane (0.05 vol% or 0.5 vol% bis-1,2-(triethoxysilyl)ethane) were assessed. It was concluded that the use of the experimental primer of 3-isocyanatopropyltrimethoxysilane at either 0.1 vol% or 1 vol% with cross-linking silane resulted in significantly higher shear bond strengths than the use of primer without the cross-linking silane.
