Technical Data SheetLOCTITE ® 290August-2007PRODUCT DESCRIPTIONLOCTITE ® 290 provides the following productcharacteristics:TechnologyAcrylicChemical Type Dimethacrylate esterAppearance (uncured) Green liquid LMSFluorescencePositive under UV light LMSComponentsOne component - requires no mixingViscosityLowCureAnaerobicSecondary Cure ActivatorApplicationThreadlockingStrengthMedium to HighLOCTITE ® 290 is designed for the locking and sealing ofthreaded fasteners. Because of its low viscosity and capillaryaction, the product wicks between engaged threads andeliminates the need to disassemble prior to application. Theproduct cures when confined in the absence of air betweenclose fitting metal surfaces and prevents loosening andleakage from shock and vibration. The product can also fillporosity in welds, castings and powdered metal parts.Mil-S-46163ALOCTITE ® 290 is tested to the lot requirements of MilitarySpecification Mil-S-46163A.ASTM D5363Each lot of adhesive produced in North America is tested tothe general requirements defined in paragraphs 5.1.1 and5.1.2 and to the Detail Requirements defined in section 5.2.TYPICAL PROPERTIES OF UNCURED MATERIALSpecific Gravity @ 25 °C 1.08Flash Point - See MSDSViscosity, Brookfield - RVT, 25 °C, mPa·s (cP):Spindle 1, speed 50 rpm20 to 55 LMSTYPICAL CURING PERFORMANCECure Speed vs. SubstrateThe rate of cure will depend on the substrate used.
