Furan resins curing agent

Polyester mortars are used in oxidizing services such as nitric and chromic acid. They are, however, more expensive than furan and also exhibit a narrower range of chemical resistance. They are usually a three-component system consisting of a resin, a powder, and a curing agent.

It is important to point out that in spite of the ease of use, these resinous mortars, like many other chemical compositions, are toxic and adequate precautions must be taken to protect the health of the applicators. For example, the skin should be protected from the setting agents used in phenolic, urea, furan, and epoxy cements and adequate ventilation should be provided during the application of polyurethane and polyester cements to prevent the inhalation of volatile isocyanates and styrene respectively. However, once they are cured, these resinous cements are not hazardous. Actually, they are important energy conserving materials of construction.
