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).

Rust-Oleum RockSolid 1-Part Epoxy. ... which can vary from 170 to 500 sq. ft. per gallon. ... Two-part epoxies require that you mix a separate hardener/catalyst into a base material, or resin. ...
Diethylenetriamine is a common curing agent for epoxy resins in epoxy adhesives and other thermosets. [4] It is N-alkylated upon reaction with epoxide groups forming crosslinks. Structure of a triamine-cured epoxy glue. The resin's epoxide groups have all reacted with the hardener.
Methylene diphenyl diisocyanate (MDI) is an aromatic diisocyanate.Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI.
The left component is Epoxy Base Resin and the right one is Epoxy Hardener. Both are to be mixed thoroughly in equal quantity to get epoxy putty. Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application.
The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction. [2]
