Stability of bisphenol A diglycidyl ether and bisphenol F diglycidyl ether in water-based food simulants
Varnishes used for the inner coatings of food cans are often based on epoxy resins or vinylic organosols. The epoxy resins can be produced from bisphenol A (BPA) and bisphenol F (BPF), and these also contain bisphenol A diglycidyl ether (BADGE) or bisphenol F diglycidyl ether (BFDGE) as stabilising components. These compounds may break down during storage and also by the influence of food simul...
متن کاملCrystal structure of the diglycidyl ether of eugenol
The diep-oxy monomer, C13H16O4 {DGE-Eu; systematic name: 2-[3-meth-oxy-4-(oxiran-2-ylmeth-oxy)benz-yl]oxirane}, was synthesized from eugenol by a three-step reaction. It consists of a 1,2,4-tris-ubstituted benzene ring substituted by diglycidyl ether, a meth-oxy group and a methyl-oxirane group. The three-membered oxirane rings are inclined to the benzene ring by 61.0 (3) and 27.9 (3)°. The met...
متن کاملSimilar dielectric behaviour of polyphenylglycidyl-ether and diglycidyl-ether of bisphenol-A at glass transition temperature
In this work, the dynamics of the primary and the Johari-Goldstein (JG) processes are studied with dielectric spectroscopy. We found the relaxations at glass transition temperature in polyphenylglycidylether and diglycidyl ether of bisphenol-A to be strongly correlated over a wide temperature T and pressure P range. Analysing the temperature and pressure behaviour of the and (JG) -processes...
متن کاملA New Flexible Soy-Based Adhesive Enhanced with Neopentyl Glycol Diglycidyl Ether: Properties and Application
Soy-based adhesives inherently possess low water resistance and brittleness, which limit their application on plywood fabrication. This investigation involves using a long chain cross-linker, neopentyl glycol diglycidyl ether (NGDE), to produce an intrinsic toughening effect to reduce the brittleness and improve the water resistance of a soybean meal–based adhesive. The solids content, viscosit...
متن کاملEffect of Zinc Oxide Nanoparticles on Mechanical Properties of Diglycidyl Ether of Bisphenol-A
This study reports on the synthesis of zinc oxide (ZnO) nanostructures and examines the performance of polymer nanocomposites fabricated using ZnO dispersed in polymer host matrices. The polymer matrix used was an epoxy based thermosetting polymer known as Diglycidyl Ether of Bisphenol-A(DGEBA). Zinc oxide nano particles were prepared by precipitation method using Poly Vinyl Alcohol as the surf...
