Product Overview
LOCTITE 401 is a fast-curing cyanoacrylate adhesive designed for demanding industrial applications. Its unique formulation enables rapid bonding of diverse materials—including metals, plastics, elastomers, and porous substrates like wood or fabric—within seconds to minutes under normal humidity. The adhesive achieves full tensile strength in 24 hours and optimal chemical resistance after 72 hours. Notably, it maintains structural integrity even when exposed to ethanol, isopropanol, and elevated temperatures, making it suitable for both indoor and outdoor use.
Advanced Features
Beyond standard performance, LOCTITE 401 offers:
Adjustable Curing Speed:
Bonds metals/alloys in <5 seconds (e.g., aluminum, steel).
Cures porous materials like oak wood in 15–30 seconds.
Activator spray accelerates curing in large gaps but may compromise peak strength.
Enhanced Durability:
Withstands up to 130% of initial strength after 1,000 hours in ethanol.
Retains ≥85% adhesion after 500 hours in motor oil at 40°C.
Safety Compliance:
Certified NSF Category P1 for non-food-contact sealing in food-processing zones (regional approval applies).
Application Scenarios
LOCTITE 401 is widely utilized in industries requiring robust, rapid bonding:
Automotive: Repairing trim, gaskets, and metal components (e.g., aluminum chassis).
Electronics: Securing plastic casings and delicate circuit board assemblies.
Industrial Manufacturing: Assembling tools, appliances, and machinery parts.
Consumer Goods: Bonding furniture, footwear, and sports equipment.
Medical: Temporary assembly in sterile environments (non-implantable applications).
