Sil-Poxy™ is a one component adhesive made specifically forbonding Smooth-On RTV moldmaking silicone rubbers to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics, etc.
Sil-Poxy™ will work with tin- or platinum-cure silicones and provides a strong, flexible bond between silicone parts with high elongation. Can be colored with Silc-Pig™ silicone pigments. Cured adhesive resists weathering, moisture, UV and high temperatures.
Sil-Poxy™ can be used repairing torn silicone rubber molds. Other applications include bonding silicone for prosthetics and animatronics
Instructions
Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.
Store and use material at room temperature (73°F/23°C). This product has a limited shelf life and should be used as soon as possible.
A clean, dry surface is essential for successful adhesive bonding. If possible, abrade surface and follow with solvent wipe before applying.
Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
Dispensing - Squeeze tube, taking care not allow air to enter tube before replacing cap. Unused product in tube exposed to air will cure quickly.
Applying - Apply adhesive to surface and mate parts. Material will begin to cure in 15 minutes. Pieces can be handled after 1 hour. Full cure is attained after 24 hours. Warmer temperatures (and higher humidity) will result in a faster cure. Lower temperature will retard cure.
