Bis-Silane is a two-part silane coupling agent designed to optimize bonding between porcelain restorations and resin cements. It comes in two separate bottles, Bis-Silane A and Bis-Silane B, each 6ml, which must be mixed before application. This system provides enhanced shelf-life stability, ensuring long-lasting and effective adhesion. Bis-Silane™ significantly improves resin's mechanical and chemical bonding to porcelain, resulting in a more durable and reliable restoration. It also protects porcelain surfaces from contamination during the bonding process and enhances resistance to water leakage at the bonding interface. This primer is versatile and suitable for all porcelain and glass-ceramic substrates, including lithium disilicate (e.max®) restorations. Bis-Silane™ is ideal for achieving strong, stable bonds in various dental restoration applications, contributing to the longevity and success of the restoration.
