## Overview

Smooth-On SIL-Poxy™ is a premium 0.5 oz one-component RTV silicone adhesive designed for strong, flexible bonding of silicone to silicone and other materials. It cures to a durable, weather-resistant seal that withstands moisture, UV exposure, and heat, making it ideal for professional repairs and creative applications in moldmaking, prosthetics, special effects, and animatronics.

## Description

Sil-Poxy is a one-component adhesive designed specifically for bonding silicone rubber to itself and a variety of other surfaces. Unlike standard adhesives, Sil-Poxy forms a strong yet flexible bond that maintains its integrity even under stress, making it ideal for both repairs and creative applications. This versatile adhesive is compatible with both tin-cure and platinum-cure RTV silicones, allowing it to seamlessly integrate into mold-making workflows. It can also bond to materials such as certain plastics, plaster, ceramics, and fabrics, making it a reliable solution for multi-material projects. Once cured, Sil-Poxy resists weathering, moisture, UV exposure, and high temperatures, ensuring long-lasting performance in demanding environments. It can also be pigmented using silicone colorants for customized applications. Common uses include repairing torn silicone molds, bonding silicone components in prosthetics and animatronics, and other specialty fabrication needs. IMPORTANT: Cured Sil-Poxy is certified skin safe. Do not apply to skin in liquid form. Note: Product packaging may vary.

Review: Great product, Worked Ahmazing, TY - Bought my daughter her most expensive yet, Full silicone babydoll. She had it over a year, takes very good care of her. We had a party a bit ago and some other kids were throwing her all over, back n forth, etc playing. Not realizing that even though she was soft, she could still be "broken" or "ripped". I took her away and later we accessed the damage. She had a huge rip across her neck, under each arm and each leg. In essence, we had to make sure that we kept her limbs and head from seperating. I did some research, this silpox came highly recommended so followed the directions in two stages due to depth of the tears by the third day we had smoothed it overand let her set one more time. She is about as close to new as she can get after that, I tugged a lil on each area, no stress so far. Ty for this product! It stinks horribly when its activating with the silicone but the ending result is Ahhhmazing. So grateful. :) If you need it, dont hesitate but follow steps to a T.
Review: The Gold Standard for Silicone Repairs – Strong, Flexible Bond That Actually Works - Smooth-On SIL-Poxy is easily one of the best adhesives available for repairing silicone. If you're working with silicone props, FX pieces, or wearable silicone items, this is essentially the industry standard. I used it to repair a large tear in the mouth area of a silicone FX mask, and the bond held extremely well once cured. The repair blended nicely and restored the integrity of the material. I also used it to fix a couple of small rips in a silicone bodysuit that occurred from putting it on and taking it off, and it handled those repairs without any issues. The adhesive cures quickly, forms a strong, flexible bond, and is specifically designed for silicone-to-silicone repairs, which most standard glues simply cannot handle. It does require a bit of patience and precision during application since silicone adhesives can be messy if overapplied, but once you get the hang of it, it works incredibly well. Overall, this is the gold standard for silicone repair products. If you need to fix silicone masks, props, or wearable silicone pieces, SIL-Poxy is one of the most reliable options available.

### ⭐⭐⭐⭐⭐ Appears to have worked well
*by F***T on May 17, 2026*

The product I hoped for, at a price I could afford, available timely, in a modest quantity that I hoped for. The translucent product had a light, smooth consistency and went on easily with scant odor. A few hours after my first experience of the product, it is thus far performing about how I hoped. As applied, I estimate that it might be slightly more rigid than the thin silicone substrate I mended. The adhesive tacked up in about 5 minutes and was durable to my light handling after about 20 minutes. Subjectively, I’m not sure if you would say the adhesive dried clear, or if you would continue to call it somewhat translucent; perhaps in between. Application technique may have some impact on perception of that.
