This topic is about finding a reliable adhesive solution to reinforce the wafer or flange of an ostomy appliance. The person is looking for an additional adhesive layer because their current barrier ring isn't providing enough hold. They have a supply of wafers that are nearing expiration and want to make sure they can still use them effectively.

Here are some suggestions and insights that might help:

1. Hollister 7730 Medical Adhesive
- Although discontinued by Hollister, it is still available in some places like McKesson.

2. Prosthetic-grade Liquid Adhesives
- Probond adhesive, which is marketed for prosthetics, is reported to work as well or better than Hollister 7730.
- "Prosthetic Medical Adhesive" sold by Skinister is suggested as a direct replacement for Hollister 7730.

3. Torbot Adhesive Options
- Skin-Tac liquid adhesive.
- Torbot double-sided adhesive discs that fit under the wafer.

4. Reinforcement Tapes & Strips
- Coloplast Extra Wide Brava Tape Extenders, which are half-moon shaped and wrap around the flange, are reported to reduce leaks and blowouts.
- Coloplast barrier strips are praised for staying in place until removed and for keeping the edge of the bag dry.
- Generic tape ideas include ordinary medical tape or double-sided carpet tape. SOOKWANG 2.5-inch double-sided tape can be cut to shape and used as a base layer under another adhesive.

5. Barrier Rings & Pastes
- Hollister Adapt barrier ring is effective for many, though it only seals around the stoma.
- Applying a thin layer of stoma paste can provide extra tack if needed.

6. General Cautions & Tips
- Be cautious with industrial or epoxy-based adhesives as they can irritate the skin. Test carefully and consider using plain tape if your skin is sensitive.
- Since individual skin reactions can vary, expect some trial and error to find the best combination of products for your needs.
