Figure 4® JEWEL MASTER GRYJewelry Castable

A versatile, high HDT master pattern material for jewelry silicone molds

Figure 4and high visualization detailed prototypes of complex and fine designs.

STUNNING SURFACE FINISH AND HIGH DEFINITION FOR JEWELRYPIECES PROTOTYPING AND PRODUCTION WITH RTV/SILICONE MOLDING
Figure 4 JEWEL MASTER GRY is a versatile master pattern material forhigh volume jewelry RTV/silicone molds and for prototype/fit models. The
material’s high heat deflection temperature (300 °C) ensures compatibility
with a range of silicones for creating molds used in jewelry castingproduction workflows.
This material also delivers exceptional precise surface quality for design
and functional prototyping, as well as snap-fit and stone-in-place testing.
Figure 4 JEWEL MASTER GRY meets biocompatibility standard ISO 10933-5
for cytotoxicity, making it safe for try-ons and fittings.
