## Overview

Sikaflex-221 is a premium one-component polyurethane sealant/adhesive that cures quickly to form a durable, elastic bond. Renowned worldwide, it offers exceptional adhesion and resistance to weather, vibration, and mechanical stress. Suitable for multiple substrates including wood, metal, ceramics, and plastics, it’s NSF approved for potable water and paintable for professional-grade finishes. Ideal for automotive, RV, and industrial applications, Sikaflex-221 delivers long-lasting, reliable sealing performance.

## Description

Sikaflex-221 is a high-quality multi-purpose non-sag 1-c polyurethane sealant/adhesive that cures on exposure to atmospheric humidity to form a durable elastomer. Sikaflex-221 bonds well to a wide variety of substrates and is suitable for making permanent elastic seals of high adhesive strength. Suitable substrate materials are wood, metals, metal primers and paint coatings (2-c systems), ceramic materials and plastics.

Review: 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: Very good
