Benzene epoxy resin of 2 phenolic formaldehyde

From;  Author:Stand originally

2 phenol and formaldehyde are in benzene between a benzene that the condensation below oxalic acid catalysis becomes quality of small opposite element after colophony of 2 phenolic formaldehyde, issue reaction of as chloric as annulus oxygen propane to be made in NaOH action again a benzene 2 phenolic formaldehyde aether of 4 shrink glycerine epoxy resin. Molecular structure style is:

Homebred model is F-76 epoxy resin. Orange yellow is ropy liquid, 130~ of annulus oxygen equivalent137g/ep, annulus oxygen is worth 0.73~0.77ep. /100g, viscosity (75 ℃ ) 2.0~2.7Pa · S. . This resinous characteristic is to have taller reaction active, the hear resistance of condensate, corrosion resistance and electric performance are good (express 1-22) . Can use as high temperature resistant pouring makings, glue sticky agent, coating reachs composite material, also can use the modifier that makes other epoxy resin.
