In sealed containers at 10-25°C. Shelf life: 12 months (tin) / 6 months (platinum).
Wear nitrile gloves. Uncurred components may cause irritation. Wash with soap if contacted.
Platinum: food/medical-safe, low odor. Tin: cost-effective but may inhibit with certain materials.
Choose optically clear grades and degas thoroughly to eliminate micro-bubbles.
Yes, use ≤3% silicone-specific pigments. Excessive pigment slows curing.
Curing too fast at high temps, insufficient support shell, or premature demolding.
Design draft angles >3°, avoid undercuts, and use tear-resistant silicones (e.g., 20-30 Shore A).
Degas insufficiently, pour too high, or apply barrier coat too thickly. Pre-wet model with silicone thinner.
Only with high-heat silicones (≥250°C rating). Standard RTV-2 degrades above 180°C.
Epoxy, polyurethane, polyester resins, wax, gypsum. Avoid sulfur-containing materials.
