Quantum Silicones L.L.C. has launched QM 132T, a mold-making silicone that can obtain with either thixotropic or flowable properties.
The durable, two-component QM 132T is RoHS compliant and well-suited for mold-making applications, Quantum Silicones said, including prototyping and replicating architectural structures, sculptures and figurines. Polyester, polyurethane and epoxy resins are compatible casting materials with this silicone.
QM 132T has a 10 to 1 mix ratio by weight and offers three catalyst options. By using QM Cat Purple, the mixed material will have a low viscosity, the company said. This enables an easy pour and thorough flow onto the master model, which contributes to creating detailed molds from complex models. Quantum said the product is ideal for vertical surface applications, and that QM Cat Clear Thixo 2 can be used to acquire a thixotropic, brushable material.
The third compatible catalyst is QM Cat Purple SR 2, Quantum Silicones said, which results in a low viscosity, flowable material. Additionally, this catalyst offers styrene resistance, resulting in increased productivity when casting styrene based resins.
QM 132T has a work life of approximately 35 minutes before the material doubles in viscosity. Its service temperature range of -50 degrees Celsius up to 150 degrees Celsius is good for casting urethanes due to the release of heat during the curing process of some urethanes. Its fast demold time ranges from 12 to 16 hours and will contribute to quick turnaround in manufacturing processes.
