Epoxy resin formulations are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, insulators, printed wiring boards (PWB), and semiconductor encapsulants. Epoxy resins are excellent electrical insulators and protect electrical components from short circuiting, dust and moisture.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).

Difunctional versions tend to give flexibility and thus toughness to epoxy resin systems. [4] [5] [6] Studies have been done on the cured properties of epoxy systems using different functionality polyetheramines. [7] As epoxy curatives, they may then be further formulated into CASE applications: coatings, adhesives, sealants, and elastomers.
Synthetic resins are of several classes. Some are manufactured by esterification of organic compounds. Some are thermosetting plastics in which the term "resin" is loosely applied to the reactant(s), the product, or both. "Resin" may be applied to one of two monomers in a copolymer, the other being called a "hardener", as in epoxy resins. For ...

It is a mixture of epoxy resin, a common raw material for PCBs and BT resins. This is in turn a mixture of bismaleimide, which is also used as a raw material for PCBs and cyanate ester . Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name.
