Choosing the Correct SILASTIC™ Moldmaking Product
Reliable mold performance starts with selecting the right silicone material. SILASTIC™ moldmaking silicones are designed to produce flexible, durable molds that capture fine details and withstand repeated use.
Used across prototyping, architectural casting, and industrial tooling, these materials support consistent results in both simple and complex mold designs.
Understanding Cure Types:
SILASTIC™ moldmaking materials are available in two primary cure systems, each suited for different applications.
Condensation Cure:
A cost-effective, versatile silicone that cures through a moisture-releasing reaction, making it more forgiving and easier to use.
- General moldmaking applications
- Good resistance to cure inhibition (more forgiving with materials)
- Flexible working and cure times
- Easy handling for standard applications
Addition Cure:
A high-performance silicone that cures without byproducts, resulting in superior accuracy, durability, and long-term dimensional stability.
- Precision and durability applications
- Minimal shrinkage after cure
- Strong chemical resistance
- Heat-accelerated cure option
- Consistent dimensional stability
Key Advantages of SILASTIC™ Moldmaking Materials
Across both cure types, these materials are built to support consistent results:
- Reproduce fine details and intricate geometries
- Maintain flexibility to reduce mold damage during demolding
- Resist tearing over multiple production cycles
- Perform across a wide temperature range
- Offer reliable release properties
SILASTIC™ silicone moldmaking materials provide a flexible solution for everything from basic reproduction to complex industrial applications. By understanding cure types, application needs, and performance requirements, you can narrow down the right product for your process.
