It offers exceptional adhesion, elasticity, and resistance to aging, weather, and both fresh and saltwater. Non-corrosive and paintable, this odorless sealant ensures durable, vibration-resistant joints in demanding environments. ## Description Resistant to fresh and salt water, as well as the strict requirements of various marine standards, Sikaflex-291i is the perfect sealant for the marine sector. Its high adhesion and elasticity make it the ideal sealant for particularly stressed joints in maritime environments. At the same time, the elastic property ensures that the joints are vibration resistant. Thanks to its unique polyurethane-based formula, the adhesive cures by humidity - at higher temperatures, this process is slightly faster, but slightly slower at lower temperatures. ## Features - Stable Einkomponentiger polyurethane sealant, the exposure to humidity, so that extending a elastomer. - Resistant to aging and weather resistant Not corrosive - Painted Over sanded odourless Wide hold - Do not conduct electricity conductive; Sea and Süwasserbeständig - Supplied as a cartridge contents: 300ml ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B006OIX414 | | Best Sellers Rank | #75,287 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #424 in Hardware Sealers | | Brand Name | SIKA | | Color | Wood | | Compatible Material | Glass | | Customer Reviews | 4.6 4.6 out of 5 stars (2,458) 4.6 out of 5 stars | | Global Trade Identification Number | 07612894819793 | | Included Components | 1 cartridge | | Item Dimensions | 48 x 48 x 230 millimeters | | Item Form | Gel | | Item Type Name | Adhesive and sealant | | Item Weight | 0.41 Kilograms | | Manufacturer | Sika | | Material Type | Polyurethane,Wood | | Model | 409648 | | Number Of Items | 1 | | Number Of Packs | 1 | | Part Number | 409648 | | Style Name | Cartridge | | Unit Count | 300 Milliliters | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** SIKA - **Item dimensions L x W x H:** 48 x 48 x 230 millimeters - **Item weight:** 0.41 Kilograms - **Material:** Polyurethane,Wood - **Style:** Cartridge ## Images ![SIKA colle-mastic Multipurpose Special Navy, 409648 - Image 1](https://m.media-amazon.com/images/I/61HEF2AEOoL.jpg) ![SIKA colle-mastic Multipurpose Special Navy, 409648 - Image 2](https://m.media-amazon.com/images/I/71jNHl55vAL.jpg) ![SIKA colle-mastic Multipurpose Special Navy, 409648 - Image 3](https://m.media-amazon.com/images/I/71uyvkI9c+L.jpg) ![SIKA colle-mastic Multipurpose Special Navy, 409648 - Image 4](https://m.media-amazon.com/images/I/71Vh-rzaZoL.jpg) ![SIKA colle-mastic Multipurpose Special Navy, 409648 - Image 5](https://m.media-amazon.com/images/I/81V8y-qcr0L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Mastic marine fiable et flexible, qualité Sikaflex garantie *by on Reviewed in France 19 June 2026* Excellent mastic marine polyuréthane Sikaflex 291i.
