<p>PRODUCT DESCRIPTION</p><p>DEDT 8416 a low viscosity surface insensitive cyanoacrylate</p><p>adhesive. Product 8416 is specifically formulated to rapidly</p><p>bond difficult substrates and to perform in lower humidity</p><p>situations. (Mil-A-46050C Type II, Class I).</p><p>TYPICAL PROPERTIES</p><p>Ester Base ethyl-2-cyanoacrylate</p><p>Appearance Clear, colourless</p><p>Flashpoint >80°C</p><p>Density 1,05</p><p>Shelf Life 12 months, unopened</p><p>Viscosity (Brookfield) @ 25°C 1300-1500cP</p><p>(Spindle 1, 20rpm)</p><p>POLYMER PROPERTIES</p><p>Appearance Clear, colourless</p><p>Softening Point c. 125°C</p><p>Refractive Index, nD20 1,45</p><p>Full Cure Time 24 hours</p><p>Solubility DMF, acetonitrile, acetone</p><p>CURED SPEED VS.

GAP</p><p>The rate of cure will depend on the bondline gap. Thin</p><p>bondlines result in high cure speeds, increasing the bond gap</p><p>will decrease the rate of cure.</p><p>CURED SPEED VS. ACTIVATOR</p><p>Where cure speed is unacceptably long due to large gaps,</p><p>applying activator to the surface will improve cure speed,</p><p>However, this can reduce ultimate strength of the bond and</p><p>therefore testing is recommended to confirm effect.</p><p>SHEAR STRENGTH</p><p>Grit Blasted Steel >15 N/mm²</p><p>Etched Aluminium >11 N/mm²</p><p>Nitrile Rubber >10 N/mm²</p><p>Polycarbonate >12 N/mm²</p><p>ABS 6~18N/mm²</p><p>PVC 6~18N/mm²</p><p>DIRECTIONS FOR USE</p><p>For best results the surface must be clean and free from</p><p>oil ,grease, rust and other contamination. Best results with</p><p>DEDT adhesive are obtained by using the minimum amount of</p><p>adhesive needed to fill the gap between the two mating</p><p>surfaces. Apply firm pressure to mated surfaces until adhesive</p><p>sets.</p><p>BLOOMING/CHLOROSIS</p><p>Vapor generated by uncured liquid adhesive can be deposited</p><p>on nearby surfaces leaving a white residue. The condition can</p><p>be reduced using one or more of the following methods:</p><p>Clean with DEDT 755.</p><p>Reduce quantity of the adhesive used.</p><p>Increase the airflow.</p><p>Speed the fixture/cure of the adhesive by using an accelerator.</p><p>PRODUCT STORAGE</p><p>Store product in the unopened container in a dry location.</p><p>Optimal storage:2℃ to 8℃. Keep container tightly capped. If</p><p>stored at low temperature, product must be allowed to return</p><p>to room temperature before use, This normally takes 8 to12</p><p>hours.</p><p>DISCLAIMER</p><p>The data contained within this Technical Data Sheet are</p><p>furnished for information only and are believed to be reliable</p><p>at the time of issue.
