Uro-Bond III Brush-On Silicone Adhesive

For anyone relying on an external catheter or male urinary sheath, a secure seal is the difference between confidence and constant worry. Uro-Bond III is a brush-on silicone adhesive built for exactly that job — a water-resistant bond that holds through activity, moisture, and hours of wear without the fuss of adhesive strips that slip or bunch. The brush applicator gives you precise control, so you coat only where you need coverage and avoid waste on the surrounding skin.

We carry Uro-Bond III in two glass-jar sizes to match how often you go through it. The 1-1/2 oz. jar (500001512) is a practical choice for occasional use or for trying it before committing to a larger supply, while the 3 oz. jar (500003) is the better value for daily wearers and caregivers managing ongoing needs. Both are silicone-based and flammable, so store them away from heat and open flame, and let the adhesive set to a tacky finish before applying the catheter for the strongest hold.

A common question is how to remove it cleanly — silicone adhesives like this are designed to release without tearing at the skin, and a compatible adhesive remover makes daily changes gentler on sensitive areas. Applying to clean, dry, oil-free skin gives the most reliable seal and the longest wear time, which is why many users prep the area thoroughly before each application.

Uro-Bond III pairs naturally with external catheters and drainage supplies, and complements skin-conditioning products such as Gold Bond for surrounding skin care between changes.
