TechnicalData Sheet LOCTITE 401 (TDS for new formulation of Loctite 401 ) February -2012 PRODUCT DESCRIPTION below shows the fixture time achieved on different materials at 22 C / 50% relative humidity. This is defined as the time to LOCTITE 401 provides the following product develop a shear strength of 0.1N/mm. characteristics: Fixture Time, seconds : Technology Cyanoacrylate Steel <5 ChemicalType Ethyl cyanoacrylate Aluminum <5 Appearance(uncured) Transparent, colorless to straw Neoprene <5 LMS colored liquid Rubber, nitrile <5 Components One part -requires no mixing ABS <5 Viscosity Low PVC <5 Cure Humidity Polycarbonate 5 to 10 Application Bonding Phenolic <5 Wood (balsa) <5 Key Substrates Metals ,Plastics and Elastomers Wood (oak) 15 to 30 Wood (pine) 15 to 20 This Technical Data Sheet is valid for LOCTITE 401 Chipboard <5 manufactured from the dates outlined in the Fabric 10 to 20Manufacturing Date Referenc section . Leather 15 to 30 Paper <5 LOCTITE 401 is designed for the assembly of difficult- to-bond materials which require uniform stress distribution and Cure Speed vs. Bond Gap strong tension and/or shear strength . The product provides The rate of cure will depend on the bondline gap. Thin bond rapid bonding of a wide range of materials, including metals, lines result inhighcure speeds, increasing the bond gapwill plastics and elastomers . LOCTITE 401 is also suited for decrease the rate of cure. bonding porous materials such as wood, paper,leather and fabric. Cure Speed vs. Humidity The rate of cure will depend on the ambient relative humidity. NSF International Higher relative humidity levels result in more rapid speed of Registered to NSF Category P1 for use as a sealant where cure . there is no possibilty of food contact in and around food processing areas. Note: This is a regional approval. Please contact your local Technical Service Center for more Cure Speed vs. Activator information and clarification. Where cure speed is unacceptably long due to large gaps, applyingactivator to the surface will improve cure speed. TYPICAL PROPERTIES OF UNCURED MATERIAL However, this can reduce ultimate strength of the bond and SpecificGravity 25 C 1.1 therefore testing is recommended to confirm effect. Flash Point -See MSDS Viscosity, Cone & Plate, mPas (cP): -1 LMS Temperature: 25 C, Shear Rate: 3,000s 70 to 110 Viscosity, Brookfield -LVF , 25 C, mPas (cP): Spindle1,speed 30 rpm 100 to 120 TYPICAL CURING PERFORMANCE Under normal conditions, the atmospheric moisture initiates the curing process. Although full functional strength is developed ina relatively short time, curing continues for at least 24 hours before full chemical/solvent resistance is developed. Cure Speed vs. Substrate The rate of cure will depend on the substrate used.
