Furane

Advantages

Better chemical resistance than Epoxies or Polyesters to acids, alkalies and solvents.  Good resistance to water penetration.  Better temperature resistance than Epoxies and Polyesters.  Excellent resistance to UV radiation. Very low smoke emission. Inherent fire resistance.

Disadvantages

Poor adhesion to porous surfaces. High exotherm and higher cure shrinkage than Epoxies.  Low viscosity makes lamination difficult.  Somewhat brittle.  Cure to black-red colour, application defects are not apparent.  Attacked by bromine, iodine and conc. chromic acid.
