TechnicalData Sheet LOCTITE 290 January -2010 PRODUCT DESCRIPTION TYPICAL PROPERTIES OF UNCURED MATERIAL Specific Gravity 25C 1.08 LOCTITE 290 provides the following product Flash Point-See MSDS characteristics: Viscosity, Brookfield -RVT , 25C, mPas (cP): Technology Acrylic LMS Spindle 1,speed 50rpm 20 to 55 Chemical Type Dimethacrylate ester LMS Appearance (uncured) Green liquid LMS Fluorescence Positive under UV light TYPICAL CURING PERFORMANCE Components One component - requires nomixing Viscosity Low Cure Speed vs. Substrate Cure Anaerobic The rate ofcure will depend onthe substrate used. The graph Secondary Cure Activator below shows the breakaway strength developed with time on Application Threadlocking M10 steel nuts andbolts compared to differentmaterials and Strength Medium to High tested according to ISO 10964. LOCTITE 290 is designed for the lockingand sealing of 100 threaded fasteners .Because of its low viscosity andcapillary action, the product wicks between engaged threads and 75 eliminates the needto disassemble prior to application . The product cures when confinedinthe absence of air between close fitting metal surfaces and prevents loosening and 50 leakage from shock and vibration . The product can also fill porosity inwelds, castings andpowdered metal parts . 25 Mil-S- 46163A 0 LOCTITE 290 is tested to the lot requirements of Military 1min 5min10min 30min1h 3h 6h 24h 72h Cure Time Specification Mil-S-46163A. Note: This is a regional approval. Please contact your local TechnicalService Center for more informationandclarification. Cure Speed vs. Bond Gap The rate of cure will depend onthe bondlinegap. Gaps in ASTM D5363 threaded fasteners depends onthread type, quality andsize . Each lot of adhesive produced inNorth America is tested to The following graph shows shear strength developed with time the general requirements definedinparagraphs 5.1.1and onsteel pins andcollars at differentcontrolled gaps andtested 5.1.2andto the Detail Requirements definedinsection 5.2. according to ISO 10123 . NSF International 100 Registered to NSF Category P1 for use as a sealant where there is no possibilty of food contact inand around food processing areas. Note: This is a regional approval. Please 75 contact your local Technical Service Center for more informationandclarification. 50 NSF International Certified to ANSI/NSFStandard 61 for use incommercial and residential potable water systems not exceeding 82 C.Note: 25 This is a regional approval.
