The dependence of the apparent activation energy for epoxy-amine reaction on degree conversion can be obtained by applying iso-conversional methods to non-isothermal cure data using differential scanning calorimetry (DSC). application three has been utilized analysis DSC commercial high solids coatings. average fully formulated product(s) is very similar that previously reported clear coats, in...

The effect of wood flour on the cure kinetics of commercial phenol-formaldehyde resins used as oriented strandboard face and core adhesives was studied using differential scanning calorimetry. The wood flour did not change the cure mechanism of the face resin, but lowered its cure temperature and activation energy and increased its cure reaction order. For the core resin (CR), the wood flour lo...

The many uncertainties in thermoset composite laminate processing can have undesirable consequences. It is impractical to address the individually. A methodology introduced this study that ranks parameters by an influence metric give insights into how reduce variability cure time most effectively. presented example considers a range of from material, geometry, and conditions within thermochemic...

The cure of polymeric 4-4’ diphenyhnethane diisocyanate, PMDI, in wood composite manufacturing has been the subject ‘of much research. The exact .contribution of polyurethane, polyurea, and polyurete formation to PMDI/wood bonding is still debated. This study foregoes the mechanism controversy and studies the cure from a panel consolidation process. Micro-dielectric analysis, JJDEA, was ut i l ...

BACKGROUND & AIMS High cure rates are achieved in HCV genotype-1b patients treated with daclatasvir and asunaprevir, DCV/ASV. Here we analyzed early HCV kinetics in genotype-1b infected Japanese subjects treated with DCV/ASV and retrospectively projected, using mathematical modeling, whether shorter treatment durations might be effective. METHODS HCV RNA levels were measured frequently during...

The effect of zinc borate (ZB) on the cure kinetics of commercial phenol–formaldehyde oriented strandboard adhesives was studied using differential scanning calorimetry. ZB caused a separation of the addition and condensation reactions for both face and core resin (CR) systems with lowered cure temperature for the addition reaction. For the face resin, ZB did not change its nth-order curing mec...
