bond-test-tnBond/adhesion testing was conducted on Crystal Ultra using a variety of CFI bonding techniques according to specifications found in ISO 10477.

In general, the CFI’s bond with Crystal Ultra is suitable if not superior to the typical composite to composite or composite to titanium bonds. This bond strength remained excellent even at high temperatures. Sand blasting was determined to be the best surface conditioning method.

In this study, Crystal Ultra was bonded to a nano-composite material and compared to a nano-composite and titanium reference bond.
