RTV-2 Silicone Material Selection Guide
Learn how to choose the right silicone based on hardness, viscosity, curing system, and application needs.
Choosing the right RTV-2 silicone is the most important step in mold making. The wrong hardness, viscosity, or curing system can lead to bubbles, tearing, or poor mold performance.
This guide will help you understand how to select the best silicone for your specific application, whether you are working with resin, concrete, or industrial molds.
Key Factors in Silicone Selection
Shore A Hardness
Viscosity
Cure System
Application-Based Selection
Concrete Molds
Concrete molds require higher hardness and strong tear resistance to handle weight and repeated use.
Resin Molds
Low viscosity and medium hardness silicone are commonly used for resin casting to capture fine details.
Soap Molds
Soft silicone is preferred for flexible molds and easy demolding.
