Permabond TA4550 is a high-performance 2-part acrylic adhesive engineered specifically for bonding nylon and polyamide materials without requiring primers or surface treatments. This versatile structural adhesive also excels at bonding metals, plastics, composites, and various other materials. With its thixotropic formula, it applies as a non-sagging gel, making it ideal for vertical applications. The adhesive cures at room temperature, offering a quick 5-10 minute fixture time and achieves working strength within 2 hours. Its 2:1 mixing ratio and low-odor formula make it user-friendly, while its maximum gap fill of 0.2 inches provides flexibility in application. The adhesive delivers excellent temperature resistance and creates strong, durable bonds. Perfect for industrial applications, TA4550 comes with a dispensing plunger and mixing nozzle for precise application. This formula serves as the official replacement for the discontinued TA4660, maintaining the same trusted bonding capabilities for nylon materials.
