On-line cure characteristics of organic strip steel coatings by infrared spectroscopy
… peaks which could be used to follow the curing reactions of the coatings. Corresponding candidate peaks were identified and quantified from specular reflectance infrared (IR) spectra of the coatings. In all instances, candidate peak heights were ratioed against reference peak heights to …

Synthesis and Characterization of Phosphine Oxide Containing Monomers and of the Flame Resistant Polymers Prepared Therefrom
… selected control systems. In addition, suitable curing schedules for epoxy networks were determined by using dielectric monitoring techniques. The curing rates varied with the structure of the monomers and were slowest for the deactivated control (4,4'aminophenyl sulfone). Epoxy networks …

Cure induced stress generation and viscoelasticity in polymer coatings.
… by free-radical polymerization and crosslinking (curing) reactions initiated with ultraviolet (UV) light do so quickly and at room temperature. Low viscosity monomer or oligiomer makes the use of volatile solvent unnecessary, decreasing energy use and making the process more environmentally …

Elevated-Temperature Oxidative Curing, Friction and Wear of Polyphenylene Sulfide (PPS) and its Composites
… of its complex processing, which involved curing reactions, and the effect of those reactions on its mechanical properties had hindered its development as a matrix for self-lubricated polymer composites. Moreover, little is known about its friction and wear behavior at high temperatures and …

Effect of Cellulose Nanocrystals on the Rheology, Curing Behavior, and Fracture Performance of Phenol-Formaldehyde Resol Resin
… could be disrupted by ultrasound treatment. The curing progressions of the resin and CNC–resin mixtures were analyzed by non-isothermal differential scanning calorimetry (DSC). The DSC curves showed two exotherms followed by an endotherm. The energy of activation for the first exotherm was …

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques
Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4-diaminodiphenylsulfone (DDS) and an ionic …

NMR investigations of cyanate resins
… many structural composites. The mechanism of the curing reactions of cyanate resins based on bisphenol-A dicyanate has been investigated both in solution and in the solidstate by NMR spectroscopy. To facilitate the study, 13C and 15N isotopic labelled cyanate resins were used. The main curing …
