3S Silicone Spray: The Essential Barrier for Mold Making & Releasing
Maximize the life of your molds and ensure flawless casts with 3S Mould Release Silicone Spray. Specifically formulated for precision manufacturing and high-detail hobbyist projects, this aerosol acts as a vital non-stick barrier during every stage of the molding process—from the initial mold creation to the final part extraction.
Optimized for the Releasing Process
This spray is your primary tool for "demolding"—removing a finished object from its mold without damage.
- Precision Demolding: Forms an ultra-thin, lubricating film of polysiloxane that allows cured resin, rubber, or plastic to separate cleanly without tearing or warping.
- Surface Perfection: Minimizes surface imperfections and air pockets by promoting uniform material flow during the pour.
- Efficiency: Reduces cycle times in industrial injection or compression molding by speeding up the ejection of "sticky" parts.
Essential for Professional Mold Making
Beyond simple releasing, 3S Silicone Spray is indispensable when constructing complex molds.
- Two-Part Mold Separation: When creating two-part molds, this spray prevents the second pour of liquid silicone from bonding permanently to the first cured half.
- Model Protection: Safely coats master models (made of wood, clay, or 3D prints) to ensure they can be easily retrieved once the mold material has set.
- Multi-Material Compatibility: Effective on molds made of glass, metal, rubber, and various plastics.
High-Performance Features
- Thermal Stability: Operates effectively at high temperatures (up to \(150^{\circ }C\)), making it ideal for heat-cured resins and industrial applications.
- Dry-Type Barrier: Dries rapidly into a non-staining, transparent layer that doesn't leave a greasy residue on your final parts.
- Non-CFC Formula: Safe for the environment and user-friendly for indoor workshops.
How to Use for Best Results
- Clean the Surface: Ensure your mold or model is free of dust and debris.
- Shake & Spray: Shake well and hold the can 30cm away. Apply a light, even coat—avoiding "pooling" in deep crevices.
- Dry Completely: Wait a few minutes for the film to set before pouring your casting material.
- Reapply: Reapply periodically for continuous production runs to maintain mold integrity.
