Epoxy resins. I. The stability of the epoxy–trimethoxyboroxine system

Journal of Applied Polymer Science, 1979
The useful life of a material depends on its environmental exposure. The diglycidyl ether of bisphenol A (DGEBA) cured with trimethoxyboroxine (TMB) was evaluated under various aging conditions. For isothermal aging, the main factor controlling weight loss appeared to be related to the diffusion of the degradation products (Eact = 22.1 kcal/mole ...

Epoxy Resin Based Polyamides as Epoxy Curing Agents

International Journal of Polymeric Materials, 1997
Abstract Novel bis ester 1,1′-(1-methyl ethylidene) bis[4-{1-(1-imino-4-ethyl benzoate)-2-pro-panolyloxy}] benzene was prepared by the reaction of epoxy resin, diglycidyl ether of bisphenol-A (DGEBA) and 4-aminoethyl benzoate. The polyamides (PAs) were prepared by the condensation of this novel bis ester with three aliphatic diamines viz; diethylene ...

Thiol-epoxy and Amine-epoxy ‘Click’ Polymerizations

2018
Although an old reaction, the interest in the thiol-epoxy reaction, especially as a polymerization process, is only recent. The power of this chemistry lies in its efficiency and operation under ambient conditions, the commercial availability of a vast variety of thiol- and epoxide-carrying molecules that can be utilized as monomers, the long list of ...

Evaluation of Lamina Properties and Fractographic Studies on Glass/Epoxy, Carbon/Epoxy and Kevlar/Epoxy Composites

Applied Mechanics and Materials, 2015
In this study the lamina properties of glass/epoxy, carbon/epoxy and kevlar/epoxy composite along their principal coordinate axes were evaluated by performing tensile test. The laminates were prepared by hand lay-up technique and compressed using a compression molding machine at 70 oc and 80 bar pressure.

Epoxy Resin

1995
Publisher Summary This chapter focuses on a study that was conducted to test for bond strength on a representative matrix of commonly used plastics and the adhesives best suited to them. The study concentrates on epoxy resin. The block-shear (ASTM D 4501) test was chosen as the test method because it places the load on a thicker section of the test ...
