Catalyzed Synthesis and Characterization of a Novel Lignin-Based Curing Agent for the Curing of High-Performance Epoxy Resin
In this study, lignin, an aromatic compound from the forestry industry, was used as a renewable material to synthesize a new aromatic amine curing agent for epoxy resin. Firstly, lignin was separated from black liquor and hydroxyl groups were converted to tosyl groups as leaving groups. Then, primary amination was conducted using an ammonia solution at high pressure and temperature, in the pres...
متن کاملCuring efficiency of four self-etching, self-adhesive resin cements.
OBJECTIVES To evaluate the degree of cure (%DC) of four self-etching, self-adhesive resin cements, and one conventional resin cement, in their self- and dual-curing mode. METHODS The self-etching, self-adhesive resin cements studied were RelyX Unicem (3M ESPE AG), Maxcem (Kerr Corporation), Biscem (Bisco, Inc.) and Multilink Sprint (Ivoclar Vivadent AG) and the classic resin cement was Multil...
متن کاملCompatibility between self-etching adhesive and self-curing resin by addition of anion exchange resin.
OBJECTIVE The aim was to investigate whether anion exchange resin powder in the OH(-) form, added to the amine component of self-cured resin can deprotonize acid groups of a self-etching adhesive and thus eliminate incompatibility caused by amine neutralization. METHODS Shear bond strength (SBS) of a self-cured CorePaste (COP), bonded either with all-in-one adhesive iBond (IBO) or with IBO co...
متن کاملEco-friendly Self-curing Concrete Incorporated with Polyethylene Glycol as Self-curing Agent (RESEARCH NOTE)
Today concrete is most generally utilized development material in the world due to its strength and sturdiness properties. To attain good strength, curing of concrete is important so we introduce the concept of self-curing concrete rather than immersion or sprinkle curing to avoid water scarcity. It was observed that water solvent polymers can be utilized as a self-curing agent, i.e. polyethyle...
