What is epoxy equivalent weight?
2 min read
Asked by: Jason Grimes
The epoxy equivalent weight (EEW) maybe defined as: the number of grams of epoxy resin required to give 1 mole of epoxy groups. The epoxy value is defined as the number of moles of epoxy group per 100g resin.
How is epoxy weight calculated?
Resin Weight = (resin ratio / (resin ratio + hardner ratio)) x desired weight.
- Total Weight = (Width x Height x Depth) / 1000 divide by a thousand when mesuring in millimeters.
- eg: 100mm Wide x 130mm High x 6mm Deep = 78000mm. …
- Now divide 78000/1000 to give you a capacity of 78mL, which is 78 grams.
How is equivalent weight calculated?
Thus to find out the equivalent weight, the atomic weight of the substance is divided by its valence. As an example, the equivalent weight of the oxygen will be equal to 16.0 g / 2 = 8.0 g.
What is epoxy index?
Epoxy index, a very important parameter to evaluate the quality of epoxy resins, is usually defined as moles of epoxy groups per 100 g of epoxy resins. This index can be used for calculating the amounts of cross-linking reagent needed in the epoxy resin formula and determining the curing degree of epoxy resins.
What is the density of epoxy?
Epoxy resin has modulus of 3.42 GPa, and possess density of 1100 kg/m3.
What is meant by equivalent weight?
equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction.
What is equivalent formula?
Using the formula: Eq = MW / n. Eq = equivalent weight. MW = atomic or molecular weight in g/mol, from periodic table. n = no. of equivalents.
Why is equivalent weight used?
Equivalent weight is defined as the mass of one equivalent of a given substance that will combine with or displace a fixed quantity of another substance. It’s useful in chemistry because it can be used to make chemically different molecules with different mass equal.
What is meant by 1 gram equivalent?
In chemistry, equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
