Review: Perfect for SportsPal aluminum canoe repair - I bought this Sika 291 to repair an aluminum canoe. This marine urethane is basically the same thing that SportsPal sells in their repair kit. I haven't used it yet but based on other reviews it will be fine for the repair I set out to accomplish Regarding other reviewers stating they received out of date or wrong colour product, I ordered black and got black and the use by date was 9 months into the future (July 2025) beyond my purchase date Nov/2024. Review: Greatest - Great stuff ## Features - Use above and below water line - Resists salt water - Fast strength build-up - Paintable and sandable - Excellent bond.Material Type: 1-C Polyurethane ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C501KD4 | | Best Sellers Rank | #120,300 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #161 in Caulk | | Brand | SIKA | | Brand Name | SIKA | | Color | Black | | Colour | Black | | Compatible Material | Metal | | Container Type | Cartridge | | Customer Reviews | 4.4 out of 5 stars 503 Reviews | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00033886005272 | | Included Components | Sealant | | Item Form | Paste | | Item Package Quantity | 1 | | Item Type Name | Adhesive | | Item Weight | 10.1 Ounces | | Item form | Paste | | Manufacturer | SIKA | | Material | Silicone | | Material Type | Silicone | | Model | 90923 | | Number of Pieces | 1 | | Other Special Features of the Product | Water Resistant | | Part Number | 017-90923 | | Special features | Water Resistant | | Specific Uses For Product | Marine | | Specific uses for product | Marine | | UPC | 033886005272 | | Unit Count | 298.69 Milliliters | | Viscosity Level | High | | Volume | 10.1 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** SIKA - **Specific uses for product:** Marine - **Material:** 1-C polyurethane - **Item form:** Paste - **Special features:** Water Resistant ## Images ![SIKAflex-291 Black Polyurethane Adhesive 10.1 fl. oz.
