A: http://www.farnell.com/datasheets/1797719.pdf

**Q: Is this safe for terrariums?**
A: This is a food safe silicone sealant that many use for aquariums so it should be fine for a terrarium.  It is definitely waterproof.

**Q: Does this product have a shelf life?**
A: Any RTV product I've ever used eventually dries up if not used within a period of time but i'm not sure how long that takes. You should only buy what you think you'll need for the job. They make this in a smaller tube if the calk gun size seems too much.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great!
*by C***N on January 31, 2025*

I had some sliding shower door handlers that kept coming off. Used this, let it cure for 48 hrs and they are on solid now!

### ⭐⭐⭐⭐⭐ great adhesive silicone
*by G***G on December 6, 2024*

needed "adhesive" silicone for a shower door application. Worked well.

### ⭐⭐⭐⭐ Expensive and Hard to Find, Works Great
*by G***. on March 15, 2023*

Essential for secure mounting of sliding glass roller brackets on our tub enclosure. Common sealers do not harden and heavy glass doors will slip downward.
