I am not the seller. I bought this 4 years ago and don't remember it. **Q: i just purchased rtv 108. i need a manufacturers certification and msds sheets please** 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 ### ⭐⭐⭐⭐⭐ Perfect for aquarium rebuilding *by S***W on 26 March 2014* ### ⭐⭐⭐⭐⭐ Worked perfectly *by A***R on 30 April 2024* ### ⭐⭐⭐ Excellent product, but the tube broke open on the ... *by R***R on 28 March 2016* ## Frequently Bought Together - Momentive RTV103 One Part Silicone Sealant, 2.8 Ounce Tube, Black - Prime-Line M 6053 Frameless Shower Door Top Bracket Roller Assembly, 3/4 In.
