Why Choose RTV2 Molding Silicone for Industrial Manufacturing?
General Purpose RTV2 Molding Silicone is an industrial-grade mold-making material known for its cost-effectiveness and ease of use. It represents an ideal Price/Performance solution for Vacuum Casting Services projects involving parts without excessively complex geometries or high volume requirements. It perfectly replicates surface details (such as leather textures or text) from the master model. It allows you to achieve high-quality results while protecting your budget, especially for artistic objects, simple industrial parts, and Low Volume Production.
Advantages
Economical Solution: More affordable than high-strength silicones, reducing overall project costs.
High Detail Reproduction: Its fluid nature allows it to penetrate fine surface details and capture perfect impressions.
Flexibility: With a medium hardness (Shore A), it allows for easy demolding of parts.
Fast Curing: Processing time can be optimized with appropriate catalysts, enabling rapid mold production.
Limitations
Tear Strength: Lower tear resistance compared to “High Strength” series; care must be taken with parts having deep undercuts.
Mold Life: Mold life (number of shots) may be slightly shorter than premium silicones when used with aggressive resins.
Heat Resistance: Standard curing range; not recommended for casting materials requiring very high temperatures.
Mechanical Properties
Standard RTV2 Silicone FAQ
What projects are suitable for General Purpose RTV2 Silicone?
General Purpose RTV2 Silicone is the most cost-effective option for non-complex industrial parts, souvenir prototypes, figures, and Concept Prototyping – Visual Models.
How many parts can be cast with this silicone?
Depending on part geometry and the casting material used, you can typically obtain 15-20 high-quality parts from standard RTV2 silicone molds. For higher volumes, consider our premium series.
What is the Shore A hardness of RTV2 Silicone?
Our general-purpose silicones typically range between 20-40 Shore A. This balance ensures the mold holds its shape while remaining flexible. For technical details on hardness, refer to Shore Hardness Scales – Smooth-On.
Is it suitable for Polyurethane Resin casting?
Yes. RTV2 molding silicone is compatible with all our polyurethane resin types (ABS-like, clear, etc.) and is successfully used in our Rapid Tooling and Casting processes.
How long does the mold-making process take?
After the master pattern is prepared, pouring and curing the RTV2 silicone typically takes 12-24 hours. The mold is then ready for production.
Does the silicone mold shrink?
The linear shrinkage of the general-purpose silicones we use is typically below 0.5%. This rate is well within acceptable limits for most visual and functional prototypes. Get a cost estimate via our Get Quote page.
