WebApr 12, 2024 · It caused the cross-linking density of the resin to rise, thus reducing the fluidity of the resin. When the MTMS content exceeded 30%, the likelihood of o-Methoxyaniline (-OCH 3) in the MTMS structure fully participating in the transesterification reaction decreased as the MTMS content increased. WebPhenolic resins are the condensation products of phenol and formaldehyde and are an important class of adhesives. They are relatively inexpensive and are manufactured as liquid compositions and films. Thermosetting phenolics withstand high temperatures both under mechanical load and in severe environments with minimal deformation and creep.
