Furane resins are produced by self-condensation of fiirfuryl alcohol with furfural. They offer possibly the best chemical resistance of any thermosetting resin in non-oxidizing conditions, and have excellent resistance to solvents. Flowever, they also require acidic catalysts that give a complication in processing. [Pg.155]

Cure of the resin plays an important part in the chemical resistance of the thermoset. Improper curing will result in a loss of corrosion resistance properties. Construction of the laminate and the t)q)e of reinforcing used also affect the corrosion resistance of the laminate. The degree and nature of the bond between the resin and the reinforcement also plays an important role. [Pg.149]

Furan thermosets are noted for their excellent resistance to solvents. They are considered to have the best overall chemical resistance of all the thermosets. They also exhibit excellent resistance to strong concentrated mineral acids, caustics, and combinations of solvents with acids and bases. [Pg.194]
