I wanted to be able to glue pads of silicone rubber on the finger tips for better heat protection and improved grip. I have struggled finding an adhesive that bonds silicone rubber very well. Once dried the rubber just peels right off until I tried this product. The pads I glued to the gloves with this product adhered perfectly. I have to really pry and pull to get any separation. Even then the rubber tears right as it gets to the point of trying to separate. My next move was to buy the $30 Sil-Poxy. There is some debate whether that will adhere well to leather. I guess I will never know because for 1/3 the price this seems to do the trick where the other 5 or 6 attempts with various other adhesives failed. I will update if any issues with adhesion develop during use. Review: Perfect for aquarium rebuilding - This is the same product that many of the aquarium builders use. This is an adhesive, which has a much higher tinsel strength and adhesion strength than the average sealant you get at the pet store. The working time is around 12 minutes. You need to plan out your assembly and go through a dry run or two before actually attempting to put it together for real. The tube was well within date, it was only a couple months old when i got it. If you are doing a tank bigger than 5 gallons, consider the calking tube. This is not the easiest to use to lay down a long even thin bead and keep it smooth and straight. It takes a decent amount of pressure with a thinner bead, you may run into hand fatigue by the time you are finishing up. ## Features - One-part white RTV silicone sealant for filling and sealing gaps or cracks up to 1/4" wide in indoor and outdoor applications - Paste consistency allows for application on vertical or overhead surfaces - Adheres to many metals, glass, ceramic, silicone rubber, and some rigid plastics without the use of primer - Continuous service range is -75 to +400 degrees F (-60 to +204 degrees C) and intermittent service range is -75 to +500 degrees F (-60 to +260 degrees C) - Meets Military Specification MIL-A-46106 and NSF Standard 51, is FDA 21 CFR 177.2600 compliant, is USDA compliant, and has UL recognized components ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004V40B1E | | Best Sellers Rank | #62,477 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #133 in Silicone Adhesives #392 in Caulk | | Brand | Momentive | | Brand Name | Momentive | | Color | White | | Compatible Material | Ceramic, Glass | | Customer Reviews | 4.6 out of 5 stars 190 Reviews | | Global Trade Identification Number | 00779008002308 | | Item Form | Paste | | Item Type Name | RTV Silicone | | Item Weight | 0.25 Kilograms | | Manufacturer | Momentive | | Material | Silicone | | Material Type | Silicone | | Model | RTV102-300ML | | Number of Items | 1 | | Part Number | RTV102 | | Style | RTV102 | | Style Name | RTV102 | | Surface Recommendation | Tile, Window, Sink, Tub, Walls | | UPC | 077027023497 779008002308 | | Unit Count | 10.1 Ounce | | Warranty Description | warranty@mgchemicals.com | | Water Resistance Level | Water Resistant | ## Product Details - **Material:** Silicone - **Brand:** Momentive - **Style:** RTV102 - **Item Weight:** 0.25 Kilograms - **Water Resistance Level:** Water Resistant ## Images ![Momentive RTV102 One Part Silicone Sealant, 10.1 Ounce Caulker, White - Image 1](https://m.media-amazon.com/images/I/31m4uRtcwYL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: What are the expiration dates for the 12 in stock?** A: 11 are 7/19 and the last one is 3/20. 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 ### ⭐⭐⭐⭐⭐ Seems To Work Well On Silicone Rubber And Leather *by R***L on July 14, 2018* I have some leather welding gloves that don't allow me to hold hot items for very long.
