It offers fast curing, strong waterproof bonds, and a clean white finish, making it ideal for professionals seeking reliable, versatile sealing solutions 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 | #66,263 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #408 in Hardware Sealers | | Brand Name | SIKA | | Color | Wood | | Compatible Material | Glass | | Customer Reviews | 4.4 4.4 out of 5 stars (104) | | 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 | | 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. ## Frequently Bought Together - Sikaflex White 291i Multifunctional adhesive sealant for marine applications, 300ml - 10 Gauge Marine Wire 10 AWG Marine Grade Wire,10/3 Triplex Tinned Copper Boat Cable,10 Gauge Oxygen-Free Copper Cable for Automotive RV Boat Speakers Solar Outdoors - 30ft - Sika Sikaflex-221 - Black - Multi-Purpose Polyurethane sealant/Adhesive - Creates Permanent Elastic Seal - Sandable/paintable - Non-Corrosive - 10.1 fl oz --- ## 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.gr/products/409121557-sika-colle-mastic-multipurpose-special-navy-409648](https://www.desertcart.gr/products/409121557-sika-colle-mastic-multipurpose-special-navy-409648) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-05*
