Denture adhesives: Cytotoxicity, microbial contamination, and formaldehyde content
The Journal of Prosthetic Dentistry, 1993Denture adhesives are extensively used to enhance retention of dentures. Denture adhesives and their leachable components are ingested, but reports on the biologic aspects of denture adhesives are scarce. This study investigated some biological properties of 19 commercially available denture adhesives.

The influence of alloy copper content on the polymerisation of anaerobic adhesives
Journal of Dentistry, 1999Anaerobic adhesives are capable of bonding copper-containing metal attachments to etched human enamel, where the latter surface has been rendered reactive by the use of a copper-containing surface activator. The aims of the present study were to determine whether copper attachments could also be successfully bonded to etched human enamel, using ...

International Journal of Adhesion and Adhesives, 2005
Abstract Different amounts of a polyisocyanate (3–5 wt%) were added to a polychloroprene (PCP) adhesive to determine their influence on the adhesion properties of an ethylene vinyl acetate copolymer containing 12 wt% vinyl acetate (EVA12). EVA12 was treated with sulphuric acid to increase its adhesion, and improved wettability, creation of carbon ...

ACS Sustainable Chemistry & Engineering, 2020
Formaldehyde-free, water-resistant, and environmentally friendly wood adhesives were prepared from starches via a simple one-step epoxidation reaction followed by cross-linking using diethylenetriamine. This study focused on the effect of amylose/amylopectin ratio of starch (high amylose, low amylose, and amylopectin) on the epoxidation reaction and on

The type of MUF adhesive formulation has been shown to have a determinant effect in the performance of MUF adhesives for wood panels upgraded with iminoamino methylene basis of the “hexamine sulphate” type. The high performance sequential MUF formulations are upgraded little or not at all by these additives.

Soluble denture adhesives: pH and sodium content.
The European journal of prosthodontics and restorative dentistry, 1997Seventeen soluble denture adhesives available in local drug stores in Belgium were selected. The pH of aqueous adhesive solutions was determined with a glass pH electrode. Sodium determinations of normal and acidified aqueous adhesive solutions were performed by means of atomic emission spectrometry.

Abstract BACKGROUND Soy protein isolate is often used to make adhesives. Inspired by the adhesion mechanism of mussel proteins, this study developed a plant‐based adhesive composed of soy protein isolate (SPI), low‐ester pectin, tannic acid (TA), and transglutaminase (TGase) for bonding ...
