PRODUCT DESCRIPTIONDEDT 8416 a low viscosity surface insensitive cyanoacrylateadhesive. Product 8416 is specifically formulated to rapidlybond difficult substrates and to perform in lower humiditysituations. (Mil-A-46050C Type II, Class I).TYPICAL PROPERTIESEster Base ethyl-2-cyanoacrylateAppearance Clear, colourlessFlashpoint >80°CDensity 1,05Shelf Life 12 months, unopenedViscosity (Brookfield) @ 25°C 1300-1500cP(Spindle 1, 20rpm)POLYMER PROPERTIESAppearance Clear, colourlessSoftening Point c. 125°CRefractive Index, nD20 1,45Full Cure Time 24 hoursSolubility DMF, acetonitrile, acetoneCURED SPEED VS. SUBSTRATEBalsa / Balsa <5 secondsRubber / Rubber <5 secondsNitrile / Nitrile <5 secondsNeoprene / Neoprene <5 secondsEPDM / EPDM <5 secondsSteel / Steel 10-20 secondsPVC / PVC 3-10 secondsPolycarbonate / Polycarbonate 10-40 secondsCURED SPEED VS. GAPThe rate of cure will depend on the bondline gap. Thinbondlines result in high cure speeds, increasing the bond gapwill decrease the rate of cure.CURED SPEED VS. ACTIVATORWhere cure speed is unacceptably long due to large gaps,applying activator to the surface will improve cure speed,However, this can reduce ultimate strength of the bond andtherefore testing is recommended to confirm effect.SHEAR STRENGTHGrit Blasted Steel >15 N/mm2Etched Aluminium >11 N/mm2Nitrile Rubber >10 N/mm2Polycarbonate >12 N/mm2ABS 6~18N/mm2PVC 6~18N/mm2DIRECTIONS FOR USEFor best results the surface must be clean and free fromoil ,grease, rust and other contamination. Best results withDEDT adhesive are obtained by using the minimum amount ofadhesive needed to fill the gap between the two matingsurfaces. Apply firm pressure to mated surfaces until adhesivesets.BLOOMING/CHLOROSISVapor generated by uncured liquid adhesive can be depositedon nearby surfaces leaving a white residue. The condition canbe reduced using one or more of the following methods:Clean with DEDT 755.Reduce quantity of the adhesive used.Increase the airflow.Speed the fixture/cure of the adhesive by using an accelerator.PRODUCT STORAGEStore product in the unopened container in a dry location.Optimal storage:2℃ to 8℃. Keep container tightly capped. Ifstored at low temperature, product must be allowed to returnto room temperature before use, This normally takes 8 to12hours.DISCLAIMERThe data contained within this Technical Data Sheet arefurnished for information only and are believed to be reliableat the time of issue.
