Ultralok® 406 – 5-Minute Flexibilized Acrylic Adhesive

Description

Ultralok® 406 is a general-purpose, flexibilized 5-minute methacrylate adhesive designed for quick, structural bonding across a wide range of materials. With a working time of just 3–6 minutes and fixture strength in 7–10 minutes, it delivers rapid, reliable bonds without extensive surface preparation. This makes it a go-to adhesive for sign manufacturers, fabricators, and general assembly applications where speed, clarity, and durability are critical.
