Diglycidyl ethers are chemical compounds used as a reactive diluents for epoxy resin. Other uses include treating textiles and stabilizing chlorinated organic compounds . Diglycidyl ether itself is extremely toxic, and can prove fatal or cause permanent damage if inhaled or consumed orally.
Addition of further Bisphenol A and a catalyst and heat can produce Bisphenol A glycidyl ether epoxy resins of higher molecular weight that are solid. [8] Structure of bisphenol-A diglycidyl ether epoxy resin: n denotes the number of polymerized subunits and is typically in the range from 0 to 25
Bisphenol F (BPF; 4,4′-dihydroxydiphenylmethane) is an organic compound with the chemical formula (HOC 6 H 4) 2 CH 2.It is structurally related to bisphenol A (BPA), a popular precursor for forming plastics, as both belong to the category of molecules known as bisphenols, which feature two phenol groups connected via a linking group.
BPA diglycidyl ether (BADGE) is used as an acid scavenger, particularly in PVC dispersions, such as organosols or plastisols, [59] [60] which are used as coatings for the inside of food cans, as well as embossed clothes designs produced using heat transfer vinyl or screen printing machines. [19] Derivatives used as flame retardants
Bis-GMA (bisphenol A-glycidyl methacrylate) is a resin commonly used in dental composite, dental sealants. [1] [2] and dental cement. It is the diester derived from methacrylic acid and the bisphenol A diglycidyl ether. Bearing two polymerizable groups, it is prone to form a crosslinked polymer that is used in dental restorations. [3]
Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects. [3] [6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, [7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.
Polyoxypropylene diglycidyl ether, a reactive diluent with the trade name of Diluent F, has an average molecular weight of 1000 and a functionality of 2 so the EEW is 1000/2 = 500. The epoxy value is defined as the number of moles of epoxy group per 100g resin.
An alernative structural comparison is as brominated form of bisphenol A diglycidyl ether. It is a brominated aromatic chemical used principally for giving flame retardant properties to materials. [1] It is TSCA and REACH registered and has the molecular formula C 21 H 20 Br 4 O 4.
