TechnicalData Sheet LOCTITE 401 (TDS fornew formulation of Loctite 401 ) February -2012 PRODUCT DESCRIPTION before full chemical/solvent resistance is developed. LOCTITE 401 provides the following product characteristics: Cure Speed vs. Substrate Technology Cyanoacrylate The rate of cure will depend on the substrate used. The table ChemicalType Ethyl cyanoacrylate below shows the fixture time achieved on differentmaterials Appearance (uncured) Transparent, colorless to straw at 22 C / 50% relative humidity. This is defined as the time to LMS colored liquid develop a shear strength of 0.1N/mm.

Wood (balsa) <5 Wood (oak) 15 to 30 Wood (pine) 15 to 20 LOCTITE 401 is designed for the assembly of difficult- Chipboard <5 to-bond materials which requireuniform stress distribution and Fabric 10 to 20 strong tension and/or shear strength . The product provides Leather 15 to 30 rapid bonding of a wide rangeof materials, including metals, Paper <5 plastics and elastomers . LOCTITE 401 is also suited for bonding porous materials such as wood, paper, leather and fabric. Cure Speed vs. Bond Gap The rate of cure will depend on the bondline gap. Thin bond lines result inhighcure speeds, increasingthe bond gap will NSF International decrease the rate of cure. Registered to NSF Category P1 for use as a sealant where there is no possibilty of food contact in and around food processing areas. Note: This is a regionalapproval. Please Cure Speed vs. Humidity contact your local Technical Service Center for more The rate of cure will depend on the ambient relative humidity. information and clarification. Higherrelative humidity levels result in more rapid speed of cure . TYPICAL PROPERTIES OF UNCURED MATERIAL SpecificGravity 25 C 1.1 Cure Speed vs. Activator Flash Point -See SDS Where cure speed is unacceptably long due to largegaps, applying activator to the surface will improve cure speed. Viscosity, Cone & Plate, mPas (cP): However, this can reduce ultimate strength of the bond and -1 LMS Temperature: 25 C, Shear Rate: 3,000s 70 to 110 therefore testing is recommended to confirmeffect. Viscosity, Brookfield -LVF , 25 C, mPas (cP): Spindle 1,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 hours80 C 60 C TDS LOCTITE 401 , February -2012 TYPICAL PERFORMANCE OF CURED MATERIAL Heat Aging Adhesive Properties Aged at temperature indicated and tested 22 C 125 Cured for 10 seconds 22 C Tensile Strength, ISO6922: LMS 100 Buna-N N/mm 6.9 (psi) ( 1,000 ) 100 C 75 Cured for 72 hours 22 C Tensile Strength, ISO6922: 50 Buna-N N/mm 13.7 120 C (psi) ( 1,900) 25 Lap Shear Strength, ISO4587: Steel (gritblasted) N/mm 20 0 (psi) ( 2,900) 0 250 500 750 1000 Aluminum (etched) N/mm 12.4 Exposure Time, hours (psi) ( 1,800) Zinc dichromate N/mm 2.5 (psi) ( 360 ) Chemical/Solvent Resistance ABS * N/mm 7.5 Aged under conditions indicated and tested 22 C * (psi) (1,090) % of initial strength PVC * N/mm 10 Environment C 100h 500h 1000h * (psi) (1,450) Motor oil 40 115 85 85 Phenolic * N/mm 12.6 * (psi) (1,820) Unleaded gasoline 22 85 90 95 Polycarbonate * N/mm 9.6 Water 22 75 80 75 * (psi) (1,400) Water/glycol 22 85 75 65 Nitrile * N/mm 1.2 * (psi) (170) Ethanol 22 100 110 130 Neoprene * N/mm 1.1 Isopropanol 22 115 100 120 * (psi) (160 ) 98% RH 40 80 65 65 Block Shear Strength, ISO13445: Polycarbonate N/mm 11 Chemical/Solvent Resistance (psi) ( 1,600) Aged under conditions indicated and tested 22C.
