Premium Spreadable Condensation Silicone for Professional Mold Making and Sealing Applications
Wacker ELASTOSIL® RT 480 is a high-quality 2-component condensation-curing (tin-cure) spreadable silicone with Shore A 55 hardness, specially developed for making spatula molds on vertical and inclined surfaces and for formed-in-place gaskets (FIPG). This professional product combines high viscosity (250,000 mPa·s) for spatula applications with excellent mechanical strength (4.5 N/mm² tensile strength) and flexible curing speed through choice of hardener.
Key Benefits
- Spreadability on vertical surfaces: High viscosity (250,000 mPa·s) prevents sagging on inclined and vertical surfaces for spatula molds and brush-on molds.
- Flexible curing speed: Choice between hardener T 37 (120 min pot life, 9 hours demolding) or T 40 (20 min pot life, 3 hours demolding) for optimal production efficiency.
- High mechanical strength: 4.5 N/mm² tensile strength and >7 N/mm tear strength for durable, long-lasting molds.
- Shore A 55 hardness: Flexible-rigid for dimensionally stable molds that retain their geometry for complex castings.
- Minimal shrinkage: 0.25% (with T 40) to 0.5% (with T 37) for dimensionally accurate reproductions.
- Wacker quality: Reliable condensation silicone from a world leader in silicone technology.
Typical Applications
- Spatula molds and brush-on molds for ornaments, statues and architectural elements on vertical surfaces
- FIPG (Formed-In-Place Gaskets): in-situ formed seals for industrial components
- Molds for art casting, sculptures and decorative objects
- Model making and prototyping where dimensionally stable, stiffer molds are required
- O-rings and seals for technical applications
- Horse hooves and veterinary impressions
Processing Instructions:
- Accurately weigh components A and B in the correct ratio
- Mix both components until a homogeneous color is achieved
- Apply with a spatula or brush to the model
- Process within the pot life and wait until fully cured before demolding
Please note – humidity dependence: Pot life and demolding time are highly dependent on the amount of component B and humidity. Higher humidity shortens processing time and demolding time.
Not suitable for: Food-safe applications (for these, use our Food-safe silicones) and skin contact/SFX (for these, use our SFX silicones).
Wacker Chemie is a world leader in silicone technologies for professional mold making, industrial sealing and technical applications with over 100 years of expertise.
