NEW STATE-OF-THE-ART GEOPOLYMER RESINS ARE OPENING NEW APPLICATIONS AND PROCEDURES, TRANSFORMING IDEAS LONG TAKEN FOR GRANTED IN THE INDUSTRY. HIGH-TEMPERATURE TECHNIQUES ARE NO LONGER NECESSARY TO OBTAIN MATERIALS WHICH ARE CERAMIC-LIKE IN THEIR PROPERTIES. GEOPOLYMERS OF THE POLY(SIALATE-DISILOXO) TYPE (-SI-O-AL-O- SI-O-SI-O-), VERY-LOW VISCOSITY INORGANIC RESINS, HARDEN LIKE THERMOSETTING ORGANIC RESINS, BUT HAVE USE-TEMPERATURE RANGE UP TO 1000 DEGREES C (1830 DEGREES F). GEOPOLYMERS PROVIDE FAITHFUL REPRODUCTION OF MOLD OR DIE SURFACE AND ALLOW FOR PRECISION AND FINENESS. GEOPOLYMER/COMPOSITE- TOOLING AND GEOPOLYMER/CASTABLE-TOOLING OFFER DIRECT REPLICATION, ON-SITE CONSTRUCTION CAPABILITIES AND VERY SHORT CURE-CYCLE. THEY ENABLE PRODUCT DESIGNERS AND TOOL MAKERS TO ENVISAGE THE USE OF CERAMIC TYPE MATERIALS WITH THE SAME FACILITY AS ORGANIC POLYMERS.
