What is epoxy value?

epoxy resin (diglycidyl ether of bisphenol A, EPON 828) is about 340 g/mol, and. number of epoxy groups of the epoxy resin is 2. In accordance with the above. equations, therefore, the stoichiometric DETA/ epoxy ratio = (103/5)/(340/2) = 12/100. (w/w).

What does Epoxy mean?

Epoxy is a very strong type of glue. Epoxy is used in the construction of airplanes and cars, among other things. While epoxy can be used for a variety of substances made of a certain chemical compound, from paints to plastics, it most commonly means an industrial-strength adhesive.

Why is epoxy so strong?

Why do they bond so strongly to surfaces? The excellent adhesive properties of epoxy resins are due to the attractive forces between the epoxy resin and the surface of the substrate. On most surfaces the forces between the surface and the epoxy resin are stronger than the forces between the epoxy resin itself.

Is epoxy waterproof?

Is Epoxy Resin Waterproof? One of the many great properties of epoxy resin – aside from the adhesion and filling attributes – is its ability to seal and form a waterproof (and anti-corrosive) layer of protection.

What are the two components of epoxy?

Two component epoxies feature unique versatility in application and performance. These systems consist of a resin and a hardener that can be formulated to offer a wide range of mechanical, thermal, optical and electrical properties.
