manufacturing process of liquid epoxy resin

Issued December 20, 1990 32

Epoxy resin was discovered in 1938 by Pierre Castan, a chemist in Switzerland. As of 1989, 137,000 tons of epoxy resin had been produced in Japan, and epoxy resin has been used in a wide range of fields, such as paints, electricity, civil engineering, and bonds. This is because epoxy resin

Epoxy Resin: Types, Uses, Properties Chemical Structure

The term epoxy, epoxy resin, or epoxide (Europe), α-epoxy, 1,2-epoxy etc. refers to a broad group of reactive compounds that are characterized by the presence of an oxirane or epoxy ring. This is represented by a three-member ring containing an oxygen atom that is bonded with two carbon atoms already united in some other way.

Epoxy Crystallization Prevention Recommendations

A liquid epoxy resin with standard bisphenol F liquid epoxy resin, will significantly decrease the tendency for the blend to crystallize. It typically takes at least a 5-10% addition of bisphenol F liquid epoxy resin to bisphenol A liquid epoxy resin (and vise versa), to have a significant impact on crystallization resistance.
