UNLABELLED One-step self-etch adhesives are undoubtedly the most user-friendly adhesives, but have been associated with lower bonding effectiveness as compared to two-step and three-step adhesives. Conversion of a one-step self-etch system into a two-step self-etch adhesive by adding a bonding step, or into a three-step etch&rinse adhesive by adding a beforehand etching step and a bonding step ...
Tissue adhesives have emerged as an alternative to sutures and staples for wound closure and reconnection of injured tissues after surgery or trauma. Owing to their convenience and effectiveness, these adhesives have received growing attention particularly in minimally invasive procedures. For safe and accurate applications, tissue adhesives should be detectable via clinical imaging modalities ...
• Penetration joints and adhesives on EPDM or asphalt roofing membranes (pitch pan) • Adhesives and sealants for crack filling or expansion joints for roofs, roads, bridges, and airport runways, providing excellent resilience, rut resistance, and adhesion to various substrates • Waterproof membranes, coatings or geomembranes for : parking decks, roof decks, terraces waste water, potable water (...
Nature often serves as a model system for developing new adhesives. In aqueous environments, mussel-inspired adhesives are promising candidates. Understanding the mechanism of the extraordinarily strong adhesive bonds of the catechol group will likely aid in the development of adhesives. With this aim, we study the adhesion of catechol-based adhesives to metal oxides on the molecular level usin...
Conventional adhesives show a decrease in the adhesion force with increasing temperature due to thermally induced viscoelastic thinning and/or structural decomposition. Here, we report the counter-intuitive behaviour of carbon nanotube (CNT) dry adhesives that show a temperature-enhanced adhesion strength by over six-fold up to 143 N cm-2 (4 mm × 4 mm), among the strongest pure CNT dry adhesive...
This study investigated the effect of the oxygen-inhibited layer on the degree of conversion (DC) of three dental adhesives, comparing two different protocols. Quartz-tungsten-halogen (QTH) light curing and light-emitting diode (LED) were used to cure three adhesives: OptiBond All in One (OAIO), Adper Easy Bond (AEB) and ExciteF (EXF). The DC was calculated utilizing Fourier Transform infrared ...
Over the last decade, the classic concept of 3-step bonding to dental tissues has developed rapidly to more user-friendly, simplified adhesive systems. These comprise the total-etch 2 step, self-etch 2step and the self-etch "all-in-one" adhesives. These adhesives carry along with simplicity some characteristics that are relevant to their efficacy in providing long-lasting bond stability. They s...
The purpose of this study was to evaluate the dentin bonding durability of three HEMA-containing one-step self-etch adhesives after one-year water storage and to measure the amounts of their water sorption/solubility. OptiBond All-In-One (OP), Bond Force (BF) and Clearfil S³Bond (S³) were applied to the dentin surfaces according to manufacturers' instructions. Bond strengths to dentin were dete...
OBJECTIVES Infectious endophthalmitis has occurred despite the use of antibiotics in irrigating solutions during implantation of intraocular lenses (IOLs). This infection is generally resistant to antibiotic therapy and, therefore, removal of the implant is necessary before eradication of the infection. This study was designed to assess the role of chosen dispersants and anti-adhesives in inhib...
Conductive inks and adhesives were used in the earliest electronics. Thomas Edison was the first to propose conductive adhesives as a way to replace wires all the way back in 1904. Today, adhesives are used with conventional etched copper circuit boards and also with other Polymer Thick Film (PTF) materials to produce electronic products that can be built very efficiently. Safe, reliable and lo...
