Smooth-On Inc.

The company introduces its “Evergreen Series” of mold rubber compounds. These rubbers contain no free isocyanates, TDI, MDI, MOCA or mercury. They were developed in response to customer requests for urethane mold rubbers that are both user and environmentally friendly. The series is currently available in Shore A hardnesses of 10, 20, 30, 40, 50 and 60. These rubbers are good for casting plaster and concrete, but are not currently recommended for wax casting.
