Cast polyurethane and polyester resin
Brooklyn-based Charles Hickok has developed techniques for casting polyurethane and polyester-based resins in a wide array of colors, hardnesses, and finishes.Polyurethane may be cast in hard, rubber, or gel formats, and these qualities may be combined in layers for abrasion-resistance. Polyurethane resin is water-clear and UV resistant, and is recommended for both interior and exterior applications. Polyurethane cast resin must be supported every 18 inches, with a maximum overhang of 9 inches.
Polyester resin is less expensive than polyurethane and is not UV resistant or perfectly water-clear. Polyester resin is available only as a hard, smooth surface, with a satin or glossy finish. Polyester resin is more brittle than polyurethane and is especially susceptible to thermal expansion and contraction. It must be supported every 12 inches, with a maximum overhang of 6 inches. Polyester resin is not fire rated, and is only recommended for interior applications.
