Furan Resin Formulations

The addition of an acid catalyst to a furan resin causes an exothermic polycondensation, which hardens the binder. Furan resins are available with different formulations, all of which are based on furfuryl alcohol ... 

This chapter is devoted to adhesives and resins prepared from totally furanic monomers or formulations in which furanic compounds are added. In this realm, only... 

Regardless of the fact that numerous investigations exist about the possibility of incorporating the furan heterocycle into wood adhesive formulations, their industrial exploitation is still modest. The first suggestion concerning the use of 1 in partial substitution of formaldehyde in phenolic resins was put forward in 1958 by Baxter and Redfern [18] who proposed that the furfural units were incorporated into the polymer skeleton following condensation reactions such as ... 

Because there are different formulations of furans, the supplier should be consulted as to the compatibility of a particular resin with the corrodents to be encoimtered. 

Phenolic thermoset resins are the oldest thermoset materials. They do not find as wide an application in the corrosion-resistant field as do the epoxies, vinyl esters, polyesters, and furans. As with other thermoset resins, they can be formulated to meet certain properties, but in general they do not have the range of corrosion resistance of the other thermosets. Table 8.6 shows their resistance to atmospheric corrosion and Table 8.7 gives their operating temperature range.
