TechnicalData Sheet LOCTITE 454 (TDS for new formulation of Loctite 454 ) January -2012 Steel 30 to 60 PRODUCT DESCRIPTION Aluminum 2 to 10 LOCTITE 454 provides the following product Neoprene 10 to 15 characteristics: Rubber, nitrile <5 Technology Cyanoacrylate ABS <5 ChemicalType Ethyl cyanoacrylate PVC 5 to 10 LMS Appearance(uncured) Clear to slightly cloudy gel Polycarbonate 10 to 15 Components One part -requires no mixing Phenolic <5 Viscosity High, thixotropic Wood (balsa) <5 Cure Humidity Wood (oak) 30 to 60 Wood (pine) 15 to 30 Application Bonding Chipboard 5 to 10 Key Substrates Metals ,Plastics and Elastomers Fabric 10 to 20 Leather 5 to 15 This Technical Data Sheet is valid for LOCTITE 454 Paper 5 to 10 manufactured from the dates outlined in the Manufacturing Date Referenc section . Cure Speed vs. Bond Gap The rate of cure will depend on the bondline gap. Thin bond lines result inhighcure speeds, increasing the bond gapwill LOCTITE 454 is designed for the assembly of difficult- decrease the rate of cure. to-bond materials which require uniform stress distribution and strong tension and/or shear strength . The product provides Cure Speed vs. Humidity rapid bonding of a wide range of materials, including metals, The rate of cure will depend on the ambient relative plastics and elastomers . The gel consistency prevents humidity. The best results are achieved when the relative adhesive flow even on vertical surfaces . LOCTITE 454 is humidity inthe working environment is 40% to 60% at 22C. also suited for bonding porous materials such as wood, paper, Lower humidity leads to slower cure. Higher humidity accelerates it,but may impairthe finalstrength of the bond. leather and fabric. NSF International Cure Speed vs. Activator Where cure speed is unacceptably long due to large gaps, Registered to NSF Category P1 for use as a sealant where applyingactivator to the surface will improve cure speed. there is no possibilty of food contact in and around food However, this can reduce ultimate strength of the bond and processing areas. Note: This is a regional approval. Please therefore testing is recommended to confirm effect. contact your local Technical Service Center for more information and clarification. TYPICAL PROPERTIES OF UNCURED MATERIAL SpecificGravity 25 C 1.1 Flash Point -See MSDS Casson Viscosity, 25 C, mPas (cP): LMS Cone and Plate Rheometer 150 to 450 Viscosity, Brookfield -RVT , 25 C, mPas (cP): LMS SpindleTC,speed 2.5 rpm,Helipath *100,000 to 300,000 LMS SpindleTC,speed 20 rpm,Helipath *18,000 to 40,000 * Appliesto material made inN.America 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. The table below shows the fixture time achieved on different materials at 22 C / 50 % relative humidity. This is defined as the time to develop a shear strength of 0.1N/mm.
