Curing Agent

Curing agent, also known as a hardener or variable agent, is a kind of material or mixture that promotes or controls curing reaction resin curing I through condensation,closed-loop, addition or catalysis and other chemical reactions so that thermosetting resin irreversible change process. Curing is completed by adding curing (cross-linking) agent. The curing agent is an essential additive, whether as an adhesive, or coating. Castable needs to add a curing agent, otherwise, the epoxy resin can not be cured. The variety of curing agents has a great influence on the mechanical properties, heat resistance, water resistance and corrosion resistance of the cured material.

What Is Curing Agent For Epoxy Resin?

There are many kinds of epoxy curing agents, and the classification methods are not the same. According to the conditions of curing with epoxy resin, it can be divided into:

Low-temperature curing agents, such as polymercaptan curing agent, modified thiourea curing agent,especially polymercaptan curing agent at minus 10 degrees celsius can also be fast curing;

Room temperature curing agent is the most widely used, the largest amount, the most kinds of curing agent, such as organic amine, modified amine, and due to the types of organic amine and different modification methods, resulting in a wide variety of amine curing agent, curing properties strange;

High-temperature curing agent, generally refers to a temperature higher than 60 degrees Celsius to and curing of epoxy resin curing agent, such as acid anhydride, polyether polyol after this kind of curing agents and epoxy resin mixed, basic at room temperature curing. or is only a preliminary crosslinking.cannot form has certain properties, such as strength and toughness of curing.

Advantages of Curing Agent

The variety of curing agent has a great impact on the mechanical properties, heat resistance, water resistance, corrosion resistance of curing agent, such as aromatic polyamine, imidazole, anhydride curing agent epoxy resin heat resistance is higher than aliphatic polyamine, low molecular polyamide curing agent; The water resistance of aromatic anhydride cured epoxy resin is better than that of aromatic diamine and aliphatic polyamine curing agent. Sanya ethyl tetraamine curing agent has good alkali resistance, but poor acid resistance and formaldehyde resistance. Alicyclic polyamines (such as isophorone diamine) cured epoxy resin has good drug resistance. The alkali resistance of epoxy resin cured by anhydride curing agent is better than acid resistance. The proper curing agent should be selected according to different application and performance requirements.
