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