Review: Rapido envio y buen funcionamiento - todo perfecto ,muy util Review: excellent produit - Ce silicone est un excellent produit. J'ai fait des tests précis de résistance à la chaleur et d'accroche sur métal (acier et aluminium). Il résiste à 250 degrés maximum (test réalisé avec un pistolet à air chaud et une sonde de température). Au delà il commence à se liquéfier et brûler. Concernant l'accroche il est impératif de très bien nettoyer la surface du support auparavant sinon le silicone n'adhère pas. Par contre si le support est nettoyé avec de l'acétone par exemple (ou même rayé avec un papier de verre), son accroche est très bonne après lui avoir laissé le temps de bien durcir, soit 24 heures. J'ai testé sur un carter de boîte de vitesse qui était fendu. Il a parfaitement accroché et est étanche. Je ne peux pas tester ce produit dans le temps mais je suppose qu'il devrait tenir assez longtemps. ## Features - Model Number: K2-B230 - Item Package Length: 9.2913385732" - Item Package Width: 1.968503935" - Item Package Height: 1.968503935" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EW6POEA | | Best Sellers Rank | 99,552 in Automotive ( See Top 100 in Automotive ) 534 in Fillers, Adhesives & Sealants | | Brand | K2 | | Customer Reviews | 4.6 4.6 out of 5 stars (492) | | Date First Available | 19 Oct. 2015 | | Item Weight | 300 g | | Item model number | K2-B230 | | Manufacturer | K2 | | Manufacturer part number | K2-B230 | | Model | Dichtstoff | | Product Dimensions | 23 x 6.6 x 4.8 cm; 300 g | | Special Features | Waterproof | ## Images ![High Temperature Silicone Sealant Dichtsi Likon, Temperature Extremes to + 350 °C, Red, 300 g - Image 1](https://m.media-amazon.com/images/I/61CdsSrekBL.jpg) ![High Temperature Silicone Sealant Dichtsi Likon, Temperature Extremes to + 350 °C, Red, 300 g - Image 2](https://m.media-amazon.com/images/I/51i36fRGo4L.jpg) ![High Temperature Silicone Sealant Dichtsi Likon, Temperature Extremes to + 350 °C, Red, 300 g - Image 3](https://m.media-amazon.com/images/I/610kDIs5y6L.jpg) ![High Temperature Silicone Sealant Dichtsi Likon, Temperature Extremes to + 350 °C, Red, 300 g - Image 4](https://m.media-amazon.com/images/I/61BLhIWRKGL.jpg) ![High Temperature Silicone Sealant Dichtsi Likon, Temperature Extremes to + 350 °C, Red, 300 g - Image 5](https://m.media-amazon.com/images/I/717EM-47i8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Rapido envio y buen funcionamiento *by O***R on 22 January 2026* todo perfecto ,muy util ### ⭐⭐⭐⭐⭐ excellent produit *by T***R on 3 September 2020* Ce silicone est un excellent produit.
