• Universal industrial instant adhesive
• Very high strength on close-fitting parts
• Reduced hazardous ingredients for improved occupational safety
• Bonds a wide range of similar or dissimilar substrates (metals, rubber, wood, cardboard, ceramics, and most plastics)
• Assembles difficult-to-bond materials using LOCTITE® SF 770 primer

Instant component bonding - your go-to fast-fixturing adhesive

A surface-insensitive, fast-fixturing instant adhesive that provides high shear strength on a wide range of materials, including difficult-to-bond substrates.

The LOCTITE® 401 is a fast-fixturing instant adhesive (industrial grade) designed for the assembly of a wide range of materials where uniform stress distribution and high tensile and/or shear strength are required. Using primer LOCTITE® SF 770, the assembly of difficult-to-bond (PP, PE, PTFE) materials is possible. In addition, it is suited for bonding porous materials such as wood, paper, leather and fabric.
