Technical Details & Test Data

Processing Data

Mix both components thoroughly for 2-3 minutes to ensure complete blending. The mix ratio is the same for all color versions of this product. This adhesive is also supplied in twin cartridges with mixing nozzles. For best results, URALANE® 5779-1 adhesives should be dispensed using manual or pneumatic dispensing equipment through a 0.25 in diameter, 20 element static mixing nozzle (Nordson EFD #7701488, or equivalent). Mix only that amount which can be processed in 5 minutes at 77°F (25°C). Material temperatures should be above 18°C (65°F) when mixing.
