Description: Accelerate your product development cycle with our premium RTV-2 silicone, engineered specifically for rapid prototyping and low-volume manufacturing.
Designed for vacuum casting applications, this high-performance silicone allows you to create precise, durable molds directly from 3D printed masters (SLA/SLS) or CNC models. Its distinct translucency enables visibility of the master model inside the cured rubber, ensuring accurate parting lines and precise cutting for complex geometries.
Key Features:
-
High Transparency: Translucent appearance facilitates visual inspection and precise cutting of parting lines (split molds).
-
Dimensional Stability: Near-zero shrinkage ensures that cast parts fit perfectly and meet strict engineering tolerances.
-
High Tear Strength: Withstands the stress of demolding complex undercuts and thin-walled parts without tearing.
-
Chemical Resistance: Formulated to resist attack from aggressive urethane casting resins (ABS-like, PP-like, clear resins), extending mold life.
-
Fast Cure Options: Available with fast-curing catalysts to speed up your prototyping workflow.
Applications:
-
Vacuum casting of polyurethane (PU) resins
-
Small batch production of plastic parts
-
Functional prototyping and fit testing
-
Replicating 3D printed models
