It is specificallyformulated for difficult to bond APPLICATIONSR apid bonding of a wide range of metal, plastic or elastomericmaterials. Particularly suitable for bonding plastic or rubber(EPDM) parts where very fast fixturing is OF UNCURED MATERIAL TypicalValueRangeChemical TypeEthyl CyanoacrylateAppearanceClear liquidSpecific Gravity @ 25 @ 25 C, (cP) Brookfield LVF Spindle 1 @ 30 rpm2010 to 30 Flash Point (TCC), C>80 TYPICAL CURING PERFORMANCEU nder normal conditions, the surface moisture initiates thehardening process.

2 Although functional strength is developedin a relatively short time, curing continues for at least 24hours before full chemical/solvent resistance is speed vs. substrateThe rate of cure will depend on substrate used. The tablebelow shows the fixture time achieved on different materials at22 C , 50% relative humidity. This is defined as the time todevelop a shear strength of N/mm2 ( psi) tested onspecimens according to ASTM Time, secondsSteel (degreased)10 to 20 Aluminium 2 to 10 Zinc dichromate30 to 90 Neoprene<5 Nitrile rubber <5 ABS 2 to 10 PVC 2 to 10 Polycarbonate 15 to 50 Phenolic materials 5 to 15 Cure speed vs. bond gapThe rate of cure will depend on the bondline gap. High curespeed is favoured by thin bond lines. Increasing the bond gapwill slow down the rate of speed vs. activatorWhere cure speed is unacceptably long due to large gaps orlow relative humidity applying activator to the surface willimprove cure speed.

3 However , this can reduce the ultimatestrength of the bond, therefore testing is recommended toconfirm speed vs. humidityThe rate of cure will depend on the ambient relative graph below shows the tensile strength developed withtime on Buna N rubber at different levels of Time, Seconds%of Full Strength20%RH40%RH60%RHTYPICAL PROPERTIES OF CURED MATERIALP hysical PropertiesCoefficient of thermal expansion, ASTM D696, K-180 x 10-6 Coefficient of thermal conductivity, ASTM C177, transition temperature, ASTM E228, C120 Electrical PropertiesConstantLossDielectric constant & loss, 25 C, ASTM D150, measured at < < < resistivity, ASTM D257, .cm1 x 1016 Surface resistivity , ASTM D257, 1 x 1016 Dielectric strength, ASTM D149, kV/mm25 TDS 406 February 1996 loctite is a Registered Trademark of loctite Corporation, Hartford, CT 06106 PERFORMANCE OF CURED MATERIAL(After 24 hr at 22 C)TypicalValueRangeShear Strength, ASTM D1002, DIN 53283 Grit Blasted Steel, N/mm 2218 to 26(psi)(3200)(2600 to 3800) Etched Aluminium, N/mm 1511 to 19(psi)(2200)(1600 to 2800) Zinc dichromate, N/mm 106 to 14(psi)(1450)(870 to 2000) ABS, N/mm 5*4 to 6(psi)(700)(600 to 800) PVC, N/mm 5*4 to 6(psi)(700)(600 to 800) Polycarbonate, N/mm 4* to (psi)(600)(550 to 650) Phenolic, N/mm 105 to 15(psi)(1450)(730 to 2900) Neoprene rubber, N/mm 105 to 15(psi)(1450)(730 to 2200) Nitrile rubber, N/mm 105 to 15(psi)(1450)(730 to 2200)

5 Directions for useFor best performance surfaces should be clean and free ofgrease. This Product performs best in thin bond gaps,( ). Excess adhesive can be dissolved with Loctiteclean up solvents, nitromethane or shall be ideally stored in a cool, dry location inunopened containers at a temperature between 8 C to 21 C(46 F to 70 F) unless otherwise labelled. Optimal storageconditions for unopened containers of cyanoacrylate productsare achieved with refrigeration: 2 C to 8 C (36 F to 46 F).Refrigerated packages shall be allowed to return to roomtemperature prior to opening and use. To preventcontamination of unused Product , do not return any material toits original container.
