Phenolic Glycidyl Ethers

They are shaped by the condensation reaction between epichlorohydrin and a phenol group. The structure of phenol-containing molecule, many phenol rings distinguish different types of epoxy resins. A showed above DGEBA (diglycidyl ether of bisphenol-A) is one of the most widely used epoxy

Modifying the ratio of epichlorohydrin to BPA during creation can generate high molecular weight resin. This HMW increases viscosity and hence these resins are solid at room temperature. Other variations in this class include hydrogenated bisphenol-A epoxy resins, brominated resins produced from tetrabromo bisphenol-A, diglycidyl ether of bisphenol-F, diglycidyl ether of bisphenol-H, diglycidyl ether of bisphenol-S etc. Brominated resins are flame retardant and mostly used in electrical uses. Further, DGEBH shows promising weather resistance and DGEBS is used to obtain thermally stable epoxy resin.

Phenol and cresol novolacs are another two types of aromatic

glycidyl ethers. They are produced by combining either phenol or cresol with formaldehyde produces a polyphenol. This polyphenol is subsequently reacted with epichlorohydrin to generate the epoxy resin with high practicality and high cured Tg.

Aromatic Glycidyl Amines

They are formed by reaction epichlorohydrin with an amine, with aromatic amines suitable temperature use. The most crucial resin in this class is tetraglycidyl methylene dianiline (TGMDA)

TGDMA resins offer excellent mechanical properties and high glass transition temperatures and suitable for advanced composited for aerospace uses.

TGPAP – Triglycidyl p-amino-phenol is another type of glycidyl amine. It exhibits low viscosity at RT and hence commonly blended with other epoxies to modify the flow or tack of the formulation without loss of Tg.

Other commercial glycidyl amines include diglycidyl aniline, tetraglycidyl meta-xylene diamine. The primary dispositive point of this class is cost which can be higher as compared to Bis-A resins.
