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).

[1] This is an important concept when using paint industrially to calculate the cost of painting. [1] It can be said that it is the real volume of paint. Here is the formula by which one can calculate the volume solid of paint, (Total sum by volume of each solid ingredient in paint x 100%)/ Total sum by volume of each ingredient in paint.
Most common cross-linkers are solid epoxy resins in so-called hybrid powders in mixing ratios of 50/50, 60/40 and 70/30 (polyester resin/ epoxy resin) for indoor applications and triglycidyl isocyanurate (TGIC) in a ratio of 93/7 and β-hydroxy alkylamide (HAA) hardener in 95/5 ratio for outdoor applications.
Two binary solutions of different compositions or even two pure components can be mixed with various mixing ratios by masses, moles, or volumes. The mass fraction of the resulting solution from mixing solutions with masses m 1 and m 2 and mass fractions w 1 and w 2 is given by:
In general there are two models, one for axial loading (Voigt model), [2] [4] and one for transverse loading (Reuss model). [ 2 ] [ 5 ] In general, for some material property E {\displaystyle E} (often the elastic modulus [ 1 ] ), the rule of mixtures states that the overall property in the direction parallel to the fibers may be as high as
Epoxy coatings have also been used in drinking water applications. [42] Epoxy coatings find much use to protect mild and other steels due to their excellent protective properties. [43] Change in color, known as yellowing, is a common phenomenon for epoxy materials and is often of concern in art and conservation applications.
