Permabond TA4631 is a versatile two-part acrylic adhesive engineered for exceptional bonding performance. This low-odor formula features a 1:1 mixing ratio and requires no primer or surface treatment, making it ideal for challenging materials like polyethylene and polypropylene. With a set time of 12-18 minutes and room temperature curing, this thin viscosity adhesive delivers outstanding impact and shear strength. It excels in bonding dissimilar materials, including metals, plastics, composites, carbon fiber, and various rubber compounds. The formula is particularly effective on low surface energy plastics and provides excellent chemical resistance. Perfect for industrial applications, this adhesive creates strong, durable bonds across a wide range of substrates, from stainless steel and aluminum to specialized materials like PTFE, nylon, and various polyolefins. Unlike its counterpart TA4630, this version contains no microbeads, making it suitable for applications with minimal gap requirements.
