Epoxy Resins

Effect of Curing Temperature on Mechanical Properties of Bio-phenolic/Epoxy Polymer Blends

“…Because of their good mechanical properties, low cost, high speci c strength, good heat and solvent tolerance, and super adhesiveness, therefore epoxy-based composite materials are commonly used in load-bearing applications, such as automotive, aerospace, building, oil and gas, and marine industries. Moreover, the value of the cured resin, which includes good adhesion to many substrates, relatively high durability (especially when rubber modi ed), high electrical resistivity, good environmental resistance, low shrinkage, and so on, as well as the ease with which the curing reaction can be tailored to accommodate the fabricating process and others industrial demand [9,10] However, the drawback of using phenolic is brittleness and shrinkage, thus, not suitable to be used in advanced engineering areas [2,11] Meanwhile, the phenol and formaldehyde (PF) resin is very costly due to the high and uctuating price of petroleum-based phenol and it has been a considerable push factor in recent decades to replace the raw materials phenol and formaldehyde in the synthetic phase to other renewable bio-based raw materials [7]. Furthermore, the primary source of raw materials for industrial phenol and formaldehyde processing is currently sourcing from petroleum-based material, thus, the various effort has been made to reduce phenol's reliance on petroleum-based due to the massive amounts emitted per year, the decline of fossil fuels, and the environmental issues connected with the use of fossil resources [1,[12][13][14] Otherwise, epoxy has poor thermal and ammability properties compared to phenolic resin, despite it has high mechanical properties, hence, is not suitable to be used in applications that involve heat and ame.…”

Analysis of differential strategies to enhance detection of low‐abundance proteins in the bovine serum proteome

“…Use of acid-labile detergents that are LC-MS/MS compatible (Chang et al, 2015) to replace SDS may directly address the problem in this approach. However, this would be an incredibly expensive solution as for the quantities required for a fractionation-based approach, commercially available TA B L E 2 Percent similarity between bovine and human serum proteins (Hodd, 1989). This is the first time that proteins separated by Relisorb ™ beads have been subjected…”

A general kinetic model for epoxy polymerization

“…This scheme is more detailed than that used by Ravindranath and Gandhi 4 and takes care of the major weaknesses of their model. A study of the several reviews [5][6][7] in the open literature suggests that the scheme in Table I is fairly general, and so should be a good starting point for the study of epoxy reactors.…”

“…Indeed, very few experimental or theoretical studies are available in the open literature on the modeling of industrial epoxy reactors. [5][6][7] This work intends to fill this gap to a small extent and attempts to provide a general mathematical framework for the study of the kinetics of the reactions. Limitations posed by heat and mass transfer effects can be incorporated subsequently, in order to develop a comprehensive reactor model.…”
