Loctite 401 Instant(bottle)

Fast Bonding Across a Wide Range of Substrates

Loctite 401 is an ethyl cyanoacrylate adhesive a one-component, low viscosity (70–120 mPa·s) formula that cures rapidly when exposed to surface moisture. On steel, aluminium, ABS, PVC, and neoprene, fixture times are under 5 seconds. Polycarbonate bonds in 5–10 seconds, while wood and leather assemblies fix in 15–30 seconds .Full bond strength develops within 24 to 72 hours. At that point, lap shear strength on grit-blasted steel is 20 N/mm², on etched aluminium 12.4 N/mm², and on PVC 10 N/mm² strong enough for most demanding structural bonding tasks in production and assembly environments. The transparent colorless-to-straw appearance means cured adhesive is barely visible on finished assemblies an important consideration in aesthetic or consumer-facing applications.

Chemical Resistance and Thermal Stability

Despite its fast cure chemistry, Loctite 401 delivers good long-term chemical resistance. Motor oil exposure at 40°C maintains 85% bond strength after 1000 hours, while ethanol and isopropanol actually show increased strength over the same period (130% and 120% respectively). Water resistance is moderate at 75%, which is adequate for most indoor industrial applications. Thermal performance holds above 50% strength up to approximately 100°C making it suitable for applications near heated components, though not for prolonged high-temperature environments. Loctite 401 carries NSF Category P1 certification meaning it's approved for use in food processing equipment where there is no direct food contact. This expands its applicability into food manufacturing, beverage, and pharmaceutical assembly operations.
