## Overview

Sika Sikaflex-221 is a white, one-component polyurethane sealant and adhesive in a 10.1 fl. oz cartridge. It bonds a wide range of materials including metals, plastics, and ceramics, cures quickly upon moisture exposure, and resists aging, seawater, and harsh chemicals. NSF-approved for use in drinking water and food production environments, it offers a durable, waterproof, and flexible seal ideal for professional-grade internal and external applications.

## Description

When you need a professional-grade elastic seal or bond, there's one name you can trust: The Sika Sikaflex-221. This multi-purpose adhesive & sealant creates permanent bonds to a wide variety of substrates to give you maximum versatility and range. It's a low-odor, non-corrosive compound that's easy and convenient to work with. For optimal performance, surfaces should be clean and free of any debris, dirt, grease, oil, or dust, then dried prior to application. Complete tooling and finishing before skin forms, typically within an hour of use.

Review: Perfect for automotive use - I used Sikaflex to adhere a roof wing to the back windshield of my car, and I’m seriously impressed with how well it worked. The bond is incredibly strong and feels permanent once cured. I let it set for about 24 hours before driving, and even after months of highway speeds and temperature changes, the wing hasn’t budged at all. The application was pretty straightforward, it has a thick, tacky consistency that gives you enough working time to position everything correctly before it starts to set. I’d recommend taping or clamping the part in place while it cures, because it does take a while to fully harden. Once cured, it’s flexible enough to handle vibration and movement, which is great for automotive use. One thing to note: this stuff is messy. It’s sticky, and once it gets on your hands or paint, it’s not easy to remove. Wear gloves, mask off surrounding areas, and have some cleaner or mineral spirits ready. Overall, Sikaflex delivered exactly what I needed, a strong, weatherproof, and vibration resistant bond that’s holding my roof wing securely in place. It’s not the cheapest adhesive, but it’s worth it for the strength and reliability.
Review: Just the product you need - Used to re-adhere the back sliding window assembly on my2015 F150. If you have the truck you know the inevitable issue where they pop off. Simply cleaned off any old adhesive and applied this and taped into position. Has been holding great ever since!
