Epoxy Adhesives: A View of the Present and the Future

Kinetics of the epoxy–thiol click reaction initiated by a tertiary amine: Calorimetric study using monofunctional components

“…Due to their high reactivity and excellent balance of properties, multifunctional aliphatic amines are the first choice as hardeners for curing at ambient temperature [1]. As the required glass transition temperatures of the products are typically higher than the cure temperature, avoiding arrest of reaction by vitrification needs either external heating or taking advantage of the polymerization heat [1,2]. In fact, it would be desirable to design a formulation exhibiting a large induction period at ambient temperature to provide workability, followed by a fast cure reaction to gain in productivity and as an internal heating source.…”

“…The diglycidyl ether of bisphenol A (DGEBA) is the most commonly used epoxy monomer. Due to their high reactivity and excellent balance of properties, multifunctional aliphatic amines are the first choice as hardeners for curing at ambient temperature [1]. As the required glass transition temperatures of the products are typically higher than the cure temperature, avoiding arrest of reaction by vitrification needs either external heating or taking advantage of the polymerization heat [1,2].…”

Solvent Assisted Pressure-Free Surface Welding and Reprocessing of Malleable Epoxy Polymers

“…Thermosetting polymers are a group of polymers extensively used in a variety of high-temperature applications, such as coatings, adhesives, composites, electrical insulators, and car bodies . They generally exhibit better thermomechanical properties and chemical resistance than thermoplastic materials due to their chemically cross-linked nature.…”
