TechnicalData Sheet LOCTITE 270 (TDS fornew formulation ofLoctite270 ) November -2009 PRODUCT DESCRIPTION TYPICAL CURING PERFORMANCE LOCTITE 270 provides the following product characteristics: Cure Speed vs. Substrate Technology Acrylic The rate ofcure willdepend onthe substrate used. The graph ChemicalType Dimethacrylate ester below shows the breakaway strength developedwith time on LMS Appearance (uncured) Green liquid M10 steel nuts and bolts compared to differentmaterials and LMS Fluorescence Positive under UV light tested accordingtoISO 10964. Components One component - requires nomixing Viscosity Low 100 Cure Anaerobic Secondary Cure Activator 80 Application Threadlocking Strength High 60 This Technical Data Sheet is valid for LOCTITE 270 Zinc dichromate 40 manufactured from the dates outlined in the Manufacturing Date Referenc section . 20 Cr free, Zinc organic LOCTITE 270 is designed forthe permanent lockingand 0 sealing ofthreaded fasteners . The product cures when 1min 5min 10min 30min 1h 3h 6h 24h 72h Cure Time confinedin the absence ofair between closefitting metal surfaces and prevents looseningand leakagefrom shock and vibration .LOCTITE 270 is particularly suited forheavy duty Cure Speed vs. Bond Gap applicationssuch as studs intomotor housings, nuts ontostuds The rate ofcure willdepend on the bondlinegap. Gaps in inpump housings and other fasteners where highstrength is threaded fasteners depends on thread type, quality and size . required . LOCTITE 270 provides robust curing The followinggraph shows shear strength developedwith time onsteel pins and collarsat differentcontrolledgaps and tested performance. It not only works on active metals (e.g.brass, accordingtoISO 10123. copper)but alsoon passive substrates such as stainless steel and plated surfaces . The product offers high temperature performance and oiltolerance.It tolerates minor surface 100 contaminations from various oils,such as cutting, lubrication, anti-corrosionand protectionfluids. 75 NSF International Registered to NSF Category P1 foruse as a sealant where 50 there is no possibilty offoodcontact in and around food processing areas.
