Product Description
LOCTITE® AA H3101 is a 2-part, highly thixotropic methacrylate adhesive designed for strong, resilient bonding at room temperature. Using a convenient 1:1 mix ratio, this adhesive cures rapidly and reaches fixturing strength within 20–25 minutes. It is engineered to work with little or no surface preparation, while maintaining excellent performance across a broad temperature range. With its non-sag formulation and ability to tolerate minor off-ratio mixing, LOCTITE® AA H3101 provides durable bonds in demanding industrial environments.
