This topic is about finding alternatives to the Hollister Adapt 7730 adhesive spray, which is used to secure a flange but has become hard to find. If you're in need of a replacement adhesive, here are some suggestions and insights that might help:

1. Prosthetic Adhesives:
- Probond (brush-on) has been effective for some users for over a year without causing skin issues. Clear formulas tend to leave less residue than white ones, and the small brush allows for precise application, offering better control compared to the 7730 spray.

2. Medical Adhesive Sprays:
- Ten Aces Med Medical Adhesive Spray is marketed as a direct substitute for the 7730, with an identical formulation. You can find it at tenacesmed.com and medicalmonks.com.

3. Skin-Tacky Liquid Wipes/Daubers:
- Skin Tac Adhesive Barrier Liquid from Torbot Group creates a very sticky surface, which is ideal for those who wear their appliances for longer periods between changes. It comes in a 4 oz bottle and can be found on the Torbot website.

4. Peripheral Securing Tape:
- Hypafix dressing retention tape is available in a 10-yard roll for about $6 on Amazon. It can be applied around the edge of the wafer, such as on a Coloplast SenSura Mio two-piece, to prevent edge lift-up from sweat or workouts, providing 5-7 days of wear time.
