price liquid resin epoxy resin1

TC-K44 is A kind of liquid epoxy resin produced by the reaction of epichlorohydrin and bisphenol A. It is the most widely used general liquid epoxy resin in the market at present, and also the standard bisphenol A epoxy resin. With it as the matrix resin, a variety of modified epoxy resin products can be generated. A variety of room temperature curing agents can be used with the liquid resin, the most commonly used aliphatic polyamines, polyamides, aliphatic cyclic amines and various modified amines, etc.

By curing the resin at high temperatures, certain properties such as chemical resistance and glass transition temperature can be improved. If anhydride or catalytic curing agent is used, high temperature curing is required and a long time after curing is required to obtain the best performance

Clear phenolic epoxy resin is rarely used alone, generally added to the curing agent filler and other auxiliary materials used. Tertiary amine as a curing agent is generally resin dosage of 5-15% and anhydride as a curing agent to add the amount of resin 0.1-3% , With a polyamine as a curing agent and epoxy resin for the 1: 1 molar ratio, using 703 as a curing agent can be 1:04 (weight ratio) with.
