Bond stress of adhesive anchor

WebExposure to some chemicals may degrade the bond strength of adhesive anchors. Refer to the product description for chemical resistance information or refer to the topic "Chemical Resistance of Adhesive Anchors" under Supplemental Topics for Anchors. Use of rodless pneumatic tools to dispense single-tube, coaxial adhesive cartridges is prohibited. WebThe lowest bond strength value was obtained in group II (9.76), the highest bond strength value was determined in group IV (20.57). The study concluded that additional chlorhexidine or ethanol treatment may not influence directly the bond strength of universal adhesives when using a single-step self etch mode of universal adhesives.
