HOW TO USE: Dry and clean the surfaces designed for bonding from dust, grease and dirt Remove old loose seal. Stick masking tape on both sides of the surface tobe bonded to ensure equal edges. Apply small amount of the silicone Remove an excees of the adhesive usinng an oiled spatula. Remove the masking tape after 8 min. Remove the cured silicone with a knife or razor blade. Review: Fantastic Results! - Fearing I would have to go to the expense of having my electric oven door front replaced after one side of it became detached, I carefully removed the screws to find that it was just the rubber "seal" that had perished. I ordered a tube of this Black High Temperature Silicone Adhesive Sealant through desertcart which arrived within a couple of days. I must admit, I was a little sceptical, but after removing the old sealant and replacing it with the new, I was very pleased with the results! I use my oven on an almost daily basis and am pleased to report that I have had no further problems. I feel quite confident that if and when the seal on the other side of the door perishes in the same way, I'll be able to fix that side too! (Not bad for a woman who usually has to ask her husband to "fix" things - and whose husband was "well impressed" by my workmanship!) Brilliant results from a product that "does what it says on the tube" which, if I'd have called out an "expert" to fix, would have probably cost me an arm and a leg but cost me just a few pounds, and there's still loads left in the tube for any future "sealing" jobs that need to be done. Review: Very good silicone for loose oven door glass - The inner glass on oven door came loose,so i took the door off,Then took the screws out holding the door together.Then i removed the loose inner glass,and cleaned the glass seal and the door .Then i put the black high temperature silicone round the seal and stuck it back together.Ithen put packing between the front and inner glass to hold the glass firmly in position. Then i put the screws back in.I left it 24 hours to set then removed the packing. Then put screws back in and re fit the door. The result was as good as new. I have used the cooker for a good month,with no problems. I would highly recommend this silicone if you have a similar problem. ## Features - HIGH QUALITY BLACK SEALANT 300ºC HEAT RESISTANT HERMETIC - Creates 100% rubber which leaves flexible at temperatures - 60ºC up to up to + 300ºC - Perfectly bonds to all smooth metal surfaces, alloys and casts glass, ceramics, plastic, wood, - mineral products, marble, stone,concrete etc. Replaces different kind of gaskets resistant to - UV radiation, changing weather conditions, oils, cooling liquids, petrol, and water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006C65ZCO | | Best Sellers Rank | 72,398 in DIY & Tools ( See Top 100 in DIY & Tools ) 990 in Sealers | | Brand | Technicqll | | Colour | Black | | Compatible Material | Cardboard, Ceramic, Concrete, Glass, Marble, Metal, Paper, Plastic, Rubber, Stone, Wood | | Container Type | Tube | | Customer Reviews | 4.4 out of 5 stars 3,561 Reviews | | Full Cure Time | 24 Hours | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Volume | 70 Millilitres | | Item Weight | 0.1 Kilograms | | Item form | Liquid | | Manufacturer | Technicqll | | Manufacturer Part Number | 9Y-Q0JV-HEWV_SML | | Material | Silicone | | Model Number | S-556 | | Number of Pieces | 1 | | Other Special Features of the Product | Heat Resistant | | Special feature | Heat Resistant | | Specific Uses For Product | Motorization, Repair | | Specific uses for product | Motorization, Repair | | Unit Count | 70.0 millilitre | | Viscosity Level | Medium to High | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Technicqll - **Item form:** Liquid - **Material:** Rubber,Silicone - **Special feature:** Heat Resistant - **Specific uses for product:** Motorization, Repair ## Images ![BLACK HIGH TEMPERATURE HT SILICONE ADHESIVE SEALANT 70ml HEAT RESISTANT 300'C - Image 1](https://m.media-amazon.com/images/I/81Fiq7eZauL.jpg) ![BLACK HIGH TEMPERATURE HT SILICONE ADHESIVE SEALANT 70ml HEAT RESISTANT 300'C - Image 2](https://m.media-amazon.com/images/I/81bGYdRToeL.jpg) ## Questions & Answers **Q: Can it be used again after one use or will it just clog up** A: Yes I have used it again on a second oven, with no clogging. **Q: Would this seal a leak in steam iron?** A: This compound is black and sticky. If the leak area would come into contact with clothing etc - NOT GOOD! I have onlu used this product to stick sound deadening layer beneath the bonnet of my car - perfect! **Q: Will this stick a glass mirror so it can be heat proof above my log fire** A: Hi, According to the manufacturer description this adhesive should bond these materials very well.Best Regards **Q: I fixed my keetle gasket but im afraid the silicone is in direct contact with the boiling water. Is it safe?** A: Hello, I used mine for fixing my kitchen cupboard lights to the underside of the units, Im not sure if it would be safe in the kettle next to your drinking water, so I would check the ingredients, or contact the manufacturer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic Results! *by S***E on 23 September 2012* Fearing I would have to go to the expense of having my electric oven door front replaced after one side of it became detached, I carefully removed the screws to find that it was just the rubber "seal" that had perished.

(The top & bottom of the liner are shown in the pics; a lot of area to be bonded!) . Couldn't screw it back as I'd inadvertently damaged the threading in the clamping screw's original hole. 🙄 I've many strong adhesives, but none that could resist oven temperatures. Googled & the only thing I found was the Technicqll. Though none of the other reviewers had used it to bond a roof liner, which is more load bearing than an oven door, I ordered it from Amazon & applied it to the areas of the liner that'd touch the oven roof, clamping it against the roof with some tight-fitting pieces of wood. Left it for 24hrs. (Needed to reapply it to one corner which I'd missed & leave for another 24hrs.) Some time after the cure time had passed I removed the wooden clamps & the liner was quite firmly bonded. 👍🏾 There was a sharp smell from the adhesive, but I'd expect this and so left the over door open after applying so it'd disperse. Obviously, as I've only just applied it, I need to actually *use* the oven & see what happens, but I'm quietly confident all will be copasetic. Based on its ease of use & minimal adhesion to surfaces you DON'T want stuck (i.e. the fingers), I'd highly recommend. (... If I don't report back after I've actually used the oven, one should assume that all *was* copasetic...!) ## Frequently Bought Together - BLACK HIGH TEMPERATURE HT SILICONE ADHESIVE SEALANT 70ml HEAT RESISTANT 300'C - Visbella V363 Silicone Oven Glass Door Gasket Seal High Temperature Heat Resistant from -80ºF to 600ºF (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/48013200-black-high-temperature-ht-silicone-adhesive-sealant-70ml-heat-resistant](https://www.desertcart.jp/products/48013200-black-high-temperature-ht-silicone-adhesive-sealant-70ml-heat-resistant) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-06*
