Loctite 401

Engineered for general industrial assembly, this high-performance instant adhesive delivers rapid fixturing and high tensile and shear strength for applications requiring uniform stress distribution. As a versatile, universal solution, it bonds a wide array of similar and dissimilar substrates—including metals, rubbers, wood, cardboard, ceramics, and most plastics. It is also exceptionally well-suited for porous materials such as paper, leather, and fabric. When paired with a compatible surface primer such as Loctite SF 770, it successfully expands its capabilities to include hard-to-bond low-energy plastics like polypropylene (PP), polyethylene (PE), and polytetrafluoroethylene (PTFE).

Key Performance Specifications

Functionality: Fast-fixturing universal instant adhesive designed for high-strength, close-fitting joints.

Material Versatility: Delivers reliable bonding across metals, elastomers, ceramics, wood, paper, leather, cardboard, and standard plastics.

Porous Substrate Compatibility: Effective for absorbent and porous materials that typically challenge standard instant adhesives.

Surface Priming Compatibility: Capable of securing difficult-to-bond engineering plastics (PP, PE, PTFE) when used in conjunction with a dedicated primer.
