LOCTITE® 401 Instant Adhesive
Features and Benefits
A surface-insensitive, fast-fixturing instant adhesive that provides high shear strength on a wide range of materials, including difficult-to-bond substrates.
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.
- 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
